Problems of erosion, reduction in shorelines, disappearance of beaches, and environmental influences have led to the recession of several economies around the world. To
resolve, designers have devised synthetic set ups like breakwaters and piers to handle a number of coastal problems such as shelter, angling, docking and shoreline line
recession. While these problems are solved, new ones emerge when breakwaters and jetties are created in the areas. Evidently, breakwater anatomist and related civil executive fields remain at their rudimentary level, even though these structures have been in use since time old. In the following research, the researcher bears out investigation in to the hydrodynamics of breakwaters, and their engineering aspects, with the view to get insight into their importance to civil engineering domains. The researcher seeks to explore, evaluate and analyse the impact of breakwaters on executive professions, and techniques their knowledge limits or opens up new channels for engineering technology. The email address details are compiled, and the researcher concludes that breakwater anatomist has great scope in contributing to civil anatomist knowledge, provided that its design and applications are researched further.
Chapter 1 Introduction
Background and Rationale
A seacoast is a geological system that is at the mercy of constant motion and change. Shorelines, beaches, and seaside areas in effect affect individual lives, and vice versa. The
diverse and sophisticated dynamics of the coastal system is the consequence of processes affecting waves, tides, currents and winds that affect the geological condition of the coastline in an attempt to keep a balance between land and drinking water. However, they are not the one factors that affect and condition coastlines. Real human activities for economical and communal purposes contribute towards its modifications. Natural processes, in conjunction with human intervention, contribute towards erosion, sedimentation, and accretion (Hsu, Lin, and Tseng 2007). Actually, according to French (1997), human activities create changes that effect the surroundings adversely by creating new habitat and lowering environment steadiness.
Though not absolutely all changes affect the surroundings adversely, however the natural procedures are damaged by the unnatural conditions. Coasts and estuaries are not indifferent towards real human intervention in which a range of modifications in their composition and environment can transform the geological, oceanological and marine system therein. Put into this status is the actual fact that coasts have grown to be the perfect place for human population, industrialisation, commercialisation transportation etc. Individuals has, in effect, taken over to build up coastal areas to act as shelters, plug-ins, docks, and for numerous alternative activities. The pressure for benefitting individual lives has undoubtedly changed the surroundings greatly towards degradation. To pay, a bunch of management strategies have been carried out to use, manage and preserve coastal areas, to regulate the activities and keep maintaining a balance between nature and mankind (d'Angremond and truck Roode 2004).
One of these management control methods is building of breakwaters and jetties. Jetties and just offshore breakwaters are synthetic structures made to protect seaside areas from the natural and unnatural downturn of the shoreline. Breakwaters are usually built parallel to the shore or at an angle to direct serious influx action from its dangerous effect on the shoreline. Jetties, on the other hand, are designed with the purpose to avoid erosion of the inlet or harbour area. Offshore breakwaters provide shelter as they are built based on influx refraction and diffraction (Putnam and Arthur, 1948). Likewise, groins are structures built to face seawards with an angle to slope at the same viewpoint as the normal beach. Groins are designed at an elevation above datum to do something as the stabilising composition and to raise the width of the beach by arresting the shoreline drift in part or all together (Paige 1950).
Apart from these, seaside areas are subjected to geological problems such as natural procedures including seaside erosion, deposition, sedimentation, tsunami, tidal
waves etc. These require real human intervention to safeguard and conserve human and natural habitat. For these purposes, an engineering field called seaside engineering has been launched in the academics arena for enhancing the data and skills of experts to develop coastal areas with reduced damage to the natural and man made environment.
Coastal engineering involves developing and protecting existing coastal safeguard use the view to anticipate future natural coastal processes. Comprehending the nature and value of coastal processes, enables technical engineers to devise programs and ways of protect these processes better. Moreover, knowledge of the coastal condition helps experts in the field to create, facilitate and do better breakwater structure. Breakwater construction is a field that is straight related with seaside engineering.
However, it also offers close relations with other anatomist fields like geology, construction, environment and computer executive. It is through this framework, that the
researcher shall be investigating the importance of breakwater anatomist and the ways it affects the engineering field.

Chapter 2 Literature Review
Breakwaters and similar coastal structures are individuals interventions, which face strong waves, currents and other marine processes. The structure of such
structures must be long lasting, as well as appropriate, with the environment. The look and building of breakwaters and interrelated buildings indicate that
knowledge of pure engineering together is not practical. In fact, it requires thought for various empirical and theoretical knowledge for its design. Towards the level of this
knowledge, the researcher is of the view that civil executive associated with large size hydraulic structures has developed considerably. Regarding to d'Angremond and van
Roode (2004), coastal problems of erosion, tides and currents have been around since the starting of civilisation. However, the management of the actions and problems have gained sizeable attention today because of the commercialization and populace of coastal areas about the world. Therefore, problems such as sea level rise, tidal asymmetry, sedimentation budget etc. need to be tackled. These are carried out through careful coastal defence and management tactics, and executive skills, which will be discussed in the next sections.
Ocean waves are produced by breeze and propagated from the ocean to the shoreline. The orbital motions of wave kinematics influence the depths and levels of the ocean bed. Near shore ocean mattresses are greatly influenced by the velocities and the influx strengths. As a result, sediment beds often change in topography due to ongoing impact of the substance causes of waves. Sedimentation response or impact is negligible, but, in effect, compound the situation of sediment transportation to and away from the neighborhood beach. The size, depth, and degree of the influence of the waves on the beach may and might not result in coastal degradation. For these reasons, detailed analysis on the continental shelves, fluid dynamics, near shore motion and variation of sea topography are needed in order to monitor and maintain the natural barrier to land. When the problems of natural erosion and sedimentation become too great to manage, measures like construction of obstacles, submerged shoals, breakwaters and manufactured headlands are carried out to sustain the surroundings (Birbena et al 2006). Building of this nature is induced by defence planning, storm handling and overflow prevention. In fact, coastal defence system and management require formation of construction for jobs to be prepared, investigated and implemented to meet the needs of the surroundings and its own people. They are the civil areas of coastal engineering (French 1997).
Not only this; constructions like breakwaters also require constant monitoring and security work to anticipate future performance. This is completed through coastal
engineering functions such as modelling to estimate the changing environment and angle of repose of shorelines, site exploration to study the cycles of hydrographic and marine life status, as well as finalizing these to create a profile for the shorelines on which breakwaters are made. For example, in Iskander et al's research (2007), the authors researched and developed a monitoring model for studying coastal structure along the El Agami part of Egypt. The analysis shows that where breakwaters exist, shoreline fluctuates, marine life is impacted, as well as influx hydraulics. Coastal engineers need to track record and study the progressive change that occurs because of the occurrence of breakwaters. Issues involving wave distribution, shoreline sand composition, coastal calibration, marine survey, and effect on the harbours' people are taken into account. Aside from these, breakwaters also have an impact on the coastal composition such as villages, plug-ins, or other such individual activities (Iskander et al 2007).
Furthermore, coastal engineers also need to ensure that the development of breakwaters and estuaries will not adversely affect individual activities as a result of design problem of these set ups. For example, in Donnell et al's article (2006), the writers show that the breakwaters on Tedious Creek estuary on the shoreline of Chesapeake
Bay in Dorchester County, MD caused significant harm to local vessels than the benefits it provided for its shelters. The set up of breakwaters is targeted at protecting the fishing boat dock and public piers from storms, but, in reality, the project's design fault has led to under performance, both in efficiency and composition to gain the locals. It is in cases such as these that coastal engineers have to be ascertained of the necessity and importance for breakwater buildings. Likewise, breakwaters can also bring about beach morphology that effectively negates the safety aim when breakwaters are constructed of limited knowledge applied associated with practical engineering. Accurate review of the shoreline area through combination shore distribution, long shore sedimentation travel rates and performance of breakwaters in advance, as well as using model calibration and validation, hydrodynamic component, influx modules etc. could favorably impact the performance of the set ups. Therefore, coastal engineers are accountable for studying the wave conditions, down drift aspect, expected erosion and current patterns behind submerged breakwater, to assess occurrence waves. These mechanisms, relating to Ranasinghe and Sato (2007), can relatively impact the function and utility of breakwaters' function. Thus, seaside anatomist is greatly affected by the sort and design of breakwaters constructions.
Breakwaters and such seaside structure construction incorporate design and functionality with the view to protect the coastal area. The design process is similar to structural design of buildings as it includes watching functional requirements, limits of the talk about of the structure, exposure, construction stages and event of
natural conditions. Breakwaters also require considerations for knowledge of development materials including quarry rock, concrete blocks, caissons and similar types of materials to use to its development. Tools for both floating and rolling breakwaters too have to be analyzed and related to the specificity of the breakwaters' site, function and design. The development of breakwaters also requires practical and structural monitoring of performance, with long lasting characteristics. According to Camfield and Holmes (1995), coastal constructions like breakwaters and jetties are influenced by very long periods of drinking water level changes. They have to be built parallel to the entrances, so that they can stabilise entrances and safe navigation. Building along the shoreline should be carried out with the way of the route in mind, to prevent migration of channel thalweg, quick shoaling and erosion of the coastline (Morang 1992 qt. Camfield and Holmes 1995). It is because engineering of jetties and breakwaters often creates a new equilibrium for the tidal system. For this purpose, studies of adjacent shorelines, natural bypass and the material that could ebb tidal activities need to be completed for effective construction of the buildings aligned with the local energetic and hydraulic operations. Construction engineering way such as cross sectional relationship of inlet and tidal prism, as well as depths of the jetties and breakwaters, and drinking water flows are researched before finding the ideal balance between performance, flow conditions, and natural marine activities.
Knowledge of construction material, as mentioned earlier, is critical for choosing and developing breakwaters to check the necessity of the local panorama and environment. Since breakwaters are made of rubble mounds or caissons or are concrete crammed, knowledge of structure material adds to the skills necessary for developing constructions for dispersing influx currents to minimise impact, as well as preserve energy from wave hydraulics where possible (World and Filianoti 2007). Not only this; new construction material knowledge also provides an edge over the design and planning of the breakwater armour unit. Reedijk et al (2008), for example, signify that the development of Xbloc by Delta Marine Consultants in 2001 has innovated armour principles in terms of designs, exams and prototypes. Xbloc are concrete blocks designed to armour shore protection and are being found in breakwater construction positively by engineers today. Muttray et al (2003), in their review of the suitability of Xbloc in breakwater engineering, point out that Xbloc are molded to suit the severe environmental conditions of waves, and such hydraulic activities. When positioned interlocked with each other, Xblocs not only reduce concrete amounts, but also achieve the stability required for achieving breakwaters impact from influx loads and harm (Muttray et al 2003; Reedijk et al (2008). Added to this fact is the expense of layering breakwaters with Xbloc, which is significantly reduced as compared to other armour blocks.
Furthermore, coastal coverage design and building require development and use of probabilistic design tools to assess uncertainties, prediction of influx impact, as
well as framework stability. One of the primary concerns for construction engineers is that the structures can sustain its operation for coastal safeguard, whatever the wave conditions and transformations of normal water bodies. The essential premise is that wave transformation in foreshores and just offshore areas can't be relied after through model designs. Actually, it requires structure engineers to know about coastal shores by using prediction models for wave transformation to review the effect of wave elevation, setup and circulation before making the breakwater and jetty buildings (Muttray et al 2001; Coduto 1999). Consideration for these aspects would help design set ups to attain its long term goals, as well as retain beach composition from long shore transfer processes.
Breakwaters are built based on executive approaches and functions that exploit the type of wave guidelines and hydraulics. Corresponding to Huizinga (2003), breakwater engineering often fails after 5 to a decade therefore of poor design. Technicians fail to understanding the concept of breakwater designs and modelling, which uses propagation of normal water around of breakwater with the assumptions that drinking water is the ideal fluid and incompressible. Waves are small in amplitude and can be analysed using the linear wave theory. Their movement is usually rotational, which can be analysed through Laplace equations. Breakwater's depth is regular and its dynamics are determined by diffraction, refraction or reflection (Huizinga 2003).
Diffraction analysis considers of this inflatable water elevation, and the connections of breakwater and waves. The influx energy is assumed to disperse as the waves touch breakwater structures, which could be recognized using linear diffraction theory. In this context, a rubble mound breakwater is a diametric form, with certain
density and diameter designed to disperse wave motion. The velocity of the waves is retarded by its action, in touch with the breakwater. The change in direction of the wave influences the sediment source, composition, influx properties, topography, and breakwater properties. Therefore, the factors in the breakwater relationship change in respond to the caisson. The fundamental assumption established is usually that the physical motion of breakwater is associated with the influx action, the permeability of the breakwater surface, seabed structure and response of the breakwater over an extended time frame (Huizinga 2003; Twu and Chieu 2000).
Alternatively, wave representation and wave run up is the model for analysing breakwater by using a cross section and slopes. In this method of engineering, wave reflection is determined by the 3 guage method. Wave conditions include relative depth, height, steepness, and breaker index. Dimension of influx conditions is accomplished by analysing its reflection at the seaward direction when the influx surface makes contact with the framework and foreshore. The water surface makes connection with the breakwater as a toe and an anti knot. The influx run up and run down impact the breakwater's wave resistance. When technicians analyse the efficacy and efficiency of breakwater, they analyze the position of the occurrence wave, as well as its reflection coefficient, to look for the impact of regular wave action. The analysis is crucial for gauging the significance of wave run up and run down on breakwater floors, and inevitably its longevity. That is achieved by using the bigger order influx theory for assimilating waves and horizontal seabed asymmetry. Furthermore, influx reflection measurement depends upon its dynamics such as local influx height, influx pressure, influx energy dissipation and wave penetration into the framework (Muttray and Oumeraci 2002). How waves break or non respite would depend on the breakwater slope and the representation placed for critical influx occurrence impact (Clyne and Mullarkey 2008).
These analytical solutions are various forms of analytical engineering, which are engaged to judge the durability, longevity, efficiency and efficiency of the breakwater features. Alternatives in analytical anatomist, therefore, help building of the breakwaters far better, as they create the baseline for stabilisation potential, as well as increase the life pattern of the structure (Wiegel 1962).
Breakwaters and jetties are engineering answers to resolve the condition of erosion and sedimentation of shorelines. These are constructed with the view to sustain
the shoreline, and subsequently benefit the neighborhood human communities. Just as breakwaters and jetties influence the hydraulic system of the areas, in addition they produce long and short term effects on marine life. Hydrodynamic conditions, sedimentation habits, wave motion, physical and chemical type factors tend to alter the composition and dynamics of the habitat. Not only this; the habitat will change in its characteristics and life cycle because of the change induced by the existence of breakwaters. No doubt, there is an imperative relationship between natural life form and breakwater set ups. Even though breakwaters are developed with the objective to provide shelter to marine life, as well as harbour for individuals activities, the type of alleviation, shoaling and usage of aquatic floral and faunal also gets impacted when breakwaters are designed without careful monitoring of quality, structure and sea lifecycle. In fact, building of breakwaters for creating inlets often ends in floral and faunal morphology of marine life due to the quality of sand, water chemical properties and the wave action. Water temperature, with variant through seasonal change, significantly affects the fish population, as well as other marine life forms. For example, the the different parts of macrozoobenthos, algaes and polychaetous worms' densities change (increase/cut down) based on the increasing or decreasing drinking water depth. Thus, building of breakwater tends to adversely impact the micro constituents of marine biology ("Biological effects of breakwater engineering" 1985).
At times, colonisation of fishes within the vicinity is influenced due to the increased turbidity's and suspended solids concentrates near the breakwater. Moreover, maintenance of the depth of access to the area, and subjection of the same, can transform the sustenance degree of fish populations. By streamlining the natural sand bypass, the morphological performance can be better to simulate waves, currents and sediment transport, which corresponds with the marine life techniques (Broker et al 2007). The reliability of the result of breakwater calibration process ensures that the constructed structure does not impede marine life forms. For this function, marine engineering knowledge, combined with breakwater development understand how, can help local engineers to establish active coastal structures to fit within the parameters of the environment.
Risks and failures
While it is clear that breakwaters have their own functionality and utility for which they are being used to support beach brand sustainability and continuity, also, they are risky. The tool and operation of breakwaters and jetties depend on the model, materials and simulation after that they have been established. Measurement for his or her horizontal and
vertical liquid velocities, breakwater structure (porous or non porous), energy dissipation rate and adjustment intensity, all contribute towards its impenetrable aspect. However, any variant and standard deviation in the look such as surface elevation, velocity variance, calibration, and framework permeability can bring about its wear and damage. Relating to Kobayashi et al (2007), breakwater permeability can affect its situation in the beach zone, effectiveness in getting rid of serious influx impact and structural longevity. In fact, breakwater transformation because of this of wave weight, pressure and speed can lead to shattering. This is dependent on the design of the breakwater and its own awareness and test against breaker proportion. Steepness of seaward slope, influx breaking motion, and wave variables greatly influence the framework, to the scope of predicting its strength (Kobayashi et al 2007).
In simple fact, Oumeraci et al (2006) are of the view that analysis of saturation scheduled to liquefaction phenomena in fine sand gravity structure tends to increase the risk of structural failure. Vertical breakwaters, especially, are vulnerable to permanent deformation of the subsoil, which brings about irreversible strains at the top stress level. Because of this,
breakwaters' structures can give way to wave load induced by the fluctuation in pressure along the seabed and the pore pressure in the concrete itself. Inability of such monumental character affects the stability, composition, and cyclic freedom.
Failure is also the consequence of the nature of the breakwater structure, whether it's designed for just offshore or onshore coastal defence. It is greatly influenced by the depth,
and dynamics of the fine sand composition within the seabed upon which the breakwater is made. The relative density of the fine sand, pressure of the liquid, as well as storm produce, all contribute towards its endurance (Oumeraci et al. 2001).
Apart from these physical dangers and failures, breakwaters are also prone in terms of their effect on marine life varieties. Changing chemical composition due to
displacement of fauna colonisation, as well a toxicity of the structures over the sediment bankers, can lead to breakwater biota fluctuations. While the human being benefits of
breakwaters last for 5 to a decade, the permanent ramifications of marine life cycle and fishery can transform the nature of the seacoast totally if careful engineering approaches aren't performed for the construction of breakwaters ("Biological ramifications of breakwater building" 1985).
The above debate has been completed with the view to provide an overview of the relationship between breakwater development and its effect on engineering areas. While engineering is a huge discipline, in this research the researcher has included executive fields related to the building of breakwaters and their maintenance. The discourse signifies that breakwater buildings are not simply coastal engineering monuments, but have multidimensional effect on the physical, biological and human
life. For this function, engineering and designing of these set ups have to be analysed, planned and implemented with care, because of its impact.
Chapter 3 Research Methodology
The aspect of research problem establishes the decision of its methods. Before one selects the research method, its aims, audience and underlying assumptions should be justified. The methodologies are then weighed and assessed to justify for its choice. The theoretical point of view of the study should provide the background certainty, as well as the constituent for increasing reader's knowledge. Within these dimensions epistemology is "concerned with providing a philosophical grounding for deciding what sorts of knowledge are possible and how we can ensure they are both satisfactory and legitimate" (Crotty 1998). The epistemology, therefore, allows the researcher to decide the application form and the underlying academic literature that's needed is for adding knowledge to the "existing consciousness. " Generally, there are two options objectivism and constructionism. The objectivistic way entails the investigation of existing knowledge and spanning it to increase its consciousness. The goal is to uncover the objective truth. On the other hand, the constructionist methodology entails the research which requires connection with the globe, and finding the truth along the way.
Underlying the constructionist procedure is the idea that research endeavours need to explore views from multiple sides before making a decision on the objective truth. This process is grounded in the qualitative strategy (Crotty 1998 qt. Levy 2006). Alternatively, research workers in the applied field usually carry out research predicated on quantitative methods that entail action research and assessments for studying particular aspects and issues. The premise for choosing action research is to endeavour to fully capture the reality with certain amount of control on the phenomena under research. Although, the nature of the coastal executive field mandates that research activities be at the mercy of quantitative empirical methods whereby experts carry out extensive action research strategies and processes.
However, in this case, the researcher has chosen the qualitative strategy as it complements the type and topic under discussion. Whereas the analysis of breakwater is pragmatic, the exploration of its connection and effect on the executive field is qualitative in aspect. Furthermore, to comprehend the implications of breakwaters and
their effect on civil engineering occupation, investigation into the subjective views of experts within the field is necessary, rather than engaging in empirical research to achieve its conclusions.
Having said that, the researcher is also aware that qualitative research requires a paradigm for basing the enquiry. Regarding to Gummesson (2000), "a paradigm is a very
general conception of the nature of scientific endeavours within which a given enquiry is performed" (p. 18). It really is a world view that allows the researcher to basic his/her
research outcomes and understanding. Research paradigms can be split into positivist, which is characterised by the planet as the exterior dimension and must be investigated through facts and fundamental regulations, and by learning concepts through sampling. Alternatively, the phenomenological paradigm requires the social building of the topic, and characterised by the knowledge of the totality of the situation by investigating the problem through founded phenomena. For the existing analysis, the researcher shall adopt the phenomenological paradigm for analysing the effect of breakwaters on the anatomist field. The rationale is based on the premise that even though through the course of discussion some complex and practical aspects shall be discussed, the analysis shall consider the ideology, decision logic and energy behind breakwaters and their link with civil anatomist fields. While the researcher appreciates that the phenomenological paradigm is not suited for engineering and technological research, he/she also offers the knowing that research of this qualitative characteristics requires interpretive understanding, somewhat than rational and objective conclusions derived from empirical and detached tests. For this function, the research shall study the behavioural (aspects?), as well as the knowledge behind the building of breakwaters as coastal defence systems. It'll attempt to rationalise through instances how breakwaters entail multidimensional of human being knowledge and anatomist skills because of their structure, as well as their maintenance.
The researcher shall count on principal and secondary resources for learning various aspects of the issue. Main resources such as literature, journals, and standard publications shall be reviewed, while secondary sources shall include periodicals, notes, the web, and other publications. Blended, these resources shall form the foundation for conversation in the books review. Once the literature review is completed, it will be evaluated predicated on different anatomist perspectives to provide conclusive results.
Chapter 4 Results and Discussion
Problems of erosion in tidal areas on earth often cause deep shorelines, climb in sea level, as well as negative sediment finances. These cannot be counteracted once the harm has been done. Theoretically, in effect, the adjustment of such coastal erosions can achieve the desired recovery status of the shoreline. The construction of barriers, submerged shoals, breakwaters, headlands and islands are some examples which can help coastal specialists to manage their coastal systems. However, these so called simple measures entail skills and understanding of executive to plan and defend the coastal area minus the implication of destroying the coast's aesthetic, biological and environmental structure. Actually, from the above conversation, one realizes that breakwaters engineering requires planning, exploration and execution of strategies that would profit both, the individuals and natural environment. The balance between your two factors is crucial as it determines if the breakwater has achieved its desired defence aim, or not.
To understand the critical aspect of breakwater related with engineering fields, at the beginning of the analysis, the researcher has layed out the following targets. After the
discussion above, the researcher shall now analyse these goals with the results of the literature reviewed.
a. Id of the many civil engineering areas that breakwaters affect
Breakwater engineering is a multi dimensional anatomist activity that inevitably effects man and fauna equally. Executive design and application concerning breakwaters are varied, and multi dimensional. As mentioned in the Literature Review, coastal engineering the over encompassing field that's needed is for the building of breakwater right from its design, planning and execution. Areas involving oceanography, sediment mattresses, sand composition, beach environment etc. , each is taken into account for measuring the range, depth and scope of the influence of breakwaters on the surroundings. Construction of structures of obstacles and headlands can
influence the outcome of the same. For these reasons, various areas of its impact such as ecosystem, coastal defence and management of the task are imperative because of its success. Executive skills in coastal field, therefore, include analysis and evaluation of coastal need, compatibility, and hindrance all contributing towards its execution. The installation of breakwaters aspires to protect people and fauna alike, therefore its design also needs to match the functional needs. Anatomist applications such as shoreline profile, coastal constructions, and knowledge of wave action, and mechanisms greatly influence breakwater function.
Conjunction with coastal anatomist, is construction anatomist, which performs a essential role for providing breakwater to life from concrete to framework formation. Without doubt, the design process is necessary for gauging the operation requirements, but its constraints, exposure, construction phases and publicity are also determined before breakwaters are designed. Moreover, breakwaters open up new sizes for insights into monitoring and morphology anatomist of these structures to ensure its durability and cost success. From the discussion, one understands that designers of breakwaters need to find out material knowledge to be able to compare (breakwater) power and functionality in conjunction with the intended construction. Discovery and understanding of material development, as well as its utilization, not only permits technical engineers to make superior quality decisions, but also add towards its endurance.
When it comes to the core development and analysis of the structures, there is absolutely no other way to measure its function, power and performance beforehand, except through simulation. For this purpose, analytical executive skills are needed to design and model the propagation of influx action, and exactly how it makes an impact on breakwaters. The dynamics of diffraction, refraction and representation analytics are critical for studying the physical morphology of sea currents and their impact on the breakwater, or even the coastline, to look for the depth and breadth of breakwaters.
b. Evaluation of how breakwaters impact civil engineering professionals; and
Having said that, the researcher realises that breakwater executive and structure greatly gives value to civil engineering specialists. Like other civil executive specialty areas like streets, dams and waterways, breakwater engineering is a speciality, which requires engineers to grasp not only the concept of breakwater designs and modelling, but also its effect on individuals life, other buildings and the surroundings.
No doubt, debate of breakwaters is focussed holistically on sedimentation, influx motion and impact; in addition they entail the analysis of rubble, concrete blocs, materials composition, and physical movement around and surrounding breakwaters. Civil engineers with understanding of breakwaters can simply transfer this knowledge to applications in other engineering fields such as bridge building, just offshore set ups and onshore set ups. The knowledge that engineers gain through breakwater building such as influx run up and run down impact, slope, reflection, wave incident and its penetration can be taken forward to be employed in progressive building engineering of waterways, underwater monuments etc. Hence, there is absolutely no doubt that the data gained is invaluable.
Despite these facts, the researcher cannot help but notice that breakwater engineering is still at the rudimentary level, in comparison with other engineering areas. The risk of failure is clearly inherent in the limited knowledge and exploration in this field. There is excellent need for discovering the depths of coastal engineering, specifically breakwaters and similar constructions to avoid them from being designed with limited life-span. Experts are of the view that breakwaters, though costly, usually previous 5 to a decade. Inevitably, they succumb to the wave oscillation motion and break down. The main element to its permanency perhaps lies in finding and research in progressive material, development design and anatomist feats that could harness wave impact and its own destructive character. It is only hence, that the efficacy and success of breakwaters can be materialised.
c. Study of the way the knowledge of breakwater construction adds to skill knowledge of engineers
Regardless of the failures and risks identified in the aforementioned section, the researcher is of the view that breakwater construction and engineering add to the engineers' skill
pool. There is excellent significance in the knowledge that breakwaters will be the initial stages of harnessing hydraulics anatomist. There is absolutely no question that future research and
investigation could lead to more innovative means of water construction. To this end, know how of engineering options, anatomist applications and architectural designs could lead to the development of a better environment for both, man and marine life. However, the furtherance of breakwater engineering and construction is limited to the
scope and extent of its function. So long as individual commercialisation and human population dominate seaside areas, breakwaters and their engineering shall be popular. This demand shall cave in to better options if people discover new options for his or her survival, regardless of the consequences of marine life. Evidence of deep sea air pollution, coastal degradation and industrialisation are some cases where one knows the devaluation of coastlines. Breakwaters, therefore, are just an option for people to harness the natural resources at sea. To ensure that they continue steadily to contribute towards real human development, breakwater executive skills have to be developed and researched. It is only through this approach that perhaps it'll enrich executive skills for the future.
Chapter 5 Conclusions
i. Breakwaters are the result of executive of varied disciplines including seaside, environment, building and analytical. It could add further knowledge to the anatomist field if and when scaled for new skills and techniques by specialists.
ii. Breakwaters are buildings that add towards betterment of both individuals and marine life circuit. However, currently, it is bound in its scope in extending its lifespan credited to limited software of marine life and material knowledge in engineering.
iii. Because of this, there's a great need for technicians to explore and exploit new dimensions to breakwaters if they want to put up with this system of planning and defending seaside areas. Taking into consideration the duration and depths of the world's coastlines, it is an important field to explore.
iv. Executive knowledge contributes towards breakwater efficacy and efficiency in building, but it's the understanding of the features and impact of breakwaters in the neighborhood environment that motivate designers to discover new avenues for its applications. For instance, the discovery of its failing due to sand liquefaction, sediment budgets and marine life dangers lead engineers to discover new approach, and perhaps new kind of structures to resolve problems of coastal erosion and sedimentation.
v. Clearly, breakwater anatomist is a fresh field that should be explored more comprehensively to find and resolve seaside engineering fields. Inevitably, it leads to
the betterment of civil anatomist perspectives as it contributes towards betterment of the civil world.
Overall, the aforementioned study demonstrates that breakwaters have been implemented, by coastal government bodies, with executive knowledge that is limiting to say minimal.
Attempts have to be taken to further this field, to be able to ensure that the continuing future of coastal, structure and biological engineering areas related to breakwaters, are anchored. Future analysts perhaps can shed light to areas such as ways to suppress liquefaction, fine sand resolving sediment budgets, and so on. Undoubtedly, knowledge gained from future research shall add value to civil engineering fields that deal with coastal set ups and their construction.
