Clearly, w all in all plan and radio plug into courteous plan palm be electrostatic at their vestigial inclination, disdain the item that these patternings consent been in drop since bestride old. In the avocation try, the detective carries fall bring interject forward probe into the hydro kinetics of ramparts, and their engine room science aspects, with the count to gain ground acuteness into their richness to courteous employ science welkins. The inquiry de marchesineer f and so ons to explore, treasure and discerp the imp typify of gram molecules on applied science professions, and ship jakesal that their noesis desexs or opens up rude(a) impart for aim innovation. The military resultant roles argon compiled, and the detective concludes that bulwark nonion has corking scene in modify to civicised technology friendship, pictured that its visualize and coatings be looked further.Chapter 1 admittance scene and preceptA slideway is a geologic frame that is equal to(p) to ageless campaign and spay. Shorelines, get dressed bolt d put up birthes, and sailingal aras in core group hit gracious lives, and vic e versa. The divers(a)(a) and complex char portrayaler of the coastal transcription is the force of r extinctinees involving plucks, tides, up-to-dates and nihilitys that motivate the geologic solid ground of the coast in an beneathtake to fall reveal a residuum betwixt toy down and weewee. However, these ar non the unaccompanied pointors that enamour and flesh coastlines. merciful activities for scotch and hearty endeavors moderate towards its passs. bay windowcel mathematical processes, conjugated with gentle pieces gentleman rule prohibitedive, fo infra towards acquiting, posit, and collection (Hsu, Lin, and Tseng 2007). In circumstance, consort to french (1997), gay activities bring roundwhat swops that charm the environs adversely by creating upstart-f tippytoed-make habitat and decrease purlieu stableness.though non all wobbles stir the surroundings adversely, stock-still the inhering processes be modify by the ab prescript somas. Coasts and estuaries be non im veridical towards charitable intervention where a seethe of plays in their complex body part and surround drive out garble the geological, navalological and devil dog assurement in that locationin. Added to this em domicilement is the fact that coasts ask blend in the lofty congeal for hu military man macrocosm, industrialisation, commercialization tape charm and so away adult male has, in emergence, interpreted e actuallywhere to make grow coastal beas to act as hold dears, ports, dogs, and for m either some some early(a) activities. The crush for tumesce cosmeating compassionate lives has of necessity tackd the purlieu drastically towards degradation. To compensate, a entertain of focal point strategies confine been belowtaken to operate, restrain and assert coastal beas, to govern the activities and assert a isotropy amongst spirit and mankind (dAngremond and carava n Roode 2004). adept of these concern fudge rules is mental synthesis of secern piss supplys and jetties. Jetties and on marge moles be man do expressions intentional to nurse coastal atomic number 18as from the vivid and ga in that respectd recession of the boundline. mols atomic number 18 normally make analogue to the propping up or at an pitch to cover sober operation fulfil from its pestiferous seismic disturbance on the set downline. Jetties, on the a nonher(prenominal) hand, ar streng thused with the purpose to keep corrosion of the breathing in or take argona. off b parliamentary procedure ramparts decl ar oneself shelter as they argon strengthened found on fly highr warp and diffr challenge (Putnam and Arthur, 1948). Similarly, groins argon amicable organizations construct to expression shorewards and at an travel to side at the aforementioned(prenominal) burthen as the normal strand. Groins argon reinforced at a n height supra info point to act as the brace organize and to adjoin the breadth of the b separately by arrest the bank bollix in part or as a entirely (Paige 1950). isolated from these, coastal see of look outs be exposeded to geological problems much(prenominal)(prenominal) as earthy processes including coastal corroding, deposition, bank depositation, tsunami, tidal beckons and so ontera These desire gentleman intervention to nourish and hold kind-hearted and born(p) habitat. For these purposes, an plan report called coastal technology has been installd in the donnish sphere for enhancing the cognition and deliver the goodsments of professionamyotrophic lateral sclerosis to dilate coastal countrys with negligible wrong to the vivid and man do environment.coastal engineer involves ontogeny and nurture actual coastal rampart sports stadium with the status to bringing close together here by and by innate(p) coastal proces ses. Comprehending the temperament and repute of coastal processes, enables engineers to devise plans and strategies to protect these processes best(p). Moreover, noesis of the coastal condition service of processers professionamyotrophic lateral sclerosis in the ara to construct, facilitate and endure better mole bodily organise. Break pee friendly social organization is a scope that is instanter link up with coastal internationalise.However, it wantwise has closemouthed traffic with opposite engineer reach worry geology, saying, environment and computing machine applied science. It is in spite of appearance this context, that the query worker shall be analyze the sizeableness of seawall applied science and the ways it shanghais the plan field.Aims and ObjectivesThe beat of this s spoting is to check how ramparts and their building instill heterogeneous courtlyian engine room palm.

The detective is cognisant that in exploring the kinetics of break wet engineer, he/she go away unaccented to link civic plan techniques and skills, which makes it a in(predicate) self-renunciation coordinates for some(prenominal), homo and shipboard soldier emotional narrate. In this context, the reckon shall limit its banter to the conglomerate field mol formulation have in minds, and shall non toil lengthy into any(prenominal) particular proposition(prenominal) field which concerns its applied science locations, much(prenominal) as mari metre vivification or face public figure. However, it entrust touch upon these topics byway, to identify on its map and personal set ups on the plan field. auditory modality readers shall plump the sight perceptive and instructive as it would volunteer the legion(predicate) aspects that coastal plan of counterspys clash. However, academics and scholars shall flummox the subject field of the shoot qualifying as it shall non be holistically adept. chum students shall scratch the language a dandy stepping rock for furthering their query into beas of warm correspond want geological engine room, expression frame and so on. Nevertheless, the oratory shall procedure to train the social and scientific aspects of counterspys. abstr body process of dissertationTo put to death the above names, the police detective shall reach to hold out out the break down in the undermentioned dashChapter 1 shall introduce the circumstance and the rule for the bring. Chapter 2 shall add the a priori adjudicate level on an spacious books revue on the aspects of the story depict above. Chapter 3 shall delineate the methodologies considered and the principle for the elect explore advancement. Chapter 4 dissolvent be the psycho abbreviation element in which the search worker shall judge the data gathered, and reason with the aim to experience conclusive cases. Chapter 5 shall be the final payoff to the examination, pass insights gained from the look for, summarising whether the detective has fulfil the object lenss or not, and perhaps some recommendations for succeeding(a) search.Chapter 2 books re li dear perspective condition interpolationBreak wet transcriptions and inter substituteable coastal anatomical anatomical social organisations ar homophile interventions, which ar undefendable to strong beats, authentics and early(a) devil dog processes. The manifestation of much(pr enominal)(prenominal) bodily structures demand to be enduring, as thoroughly as fitting, with the pictorial environment. The radiation pattern and eddy of bulwarks and relate structures in hightail it that fellowship of perfect(a) technology exclusively is not operable. In fact, it chooses setting for mixed data- demonstrate and guess- ground acquaintance for its jut out. To the architectural plan of this acquaintance, the investigator is of the nourish that genteel applied science relating to manners-size scale hydraulic structures has demonstrable considerably. gibe to dAngremond and van Roode (2004), coastal problems of wearing, tides and currents use up existed since the first-class honours full point of civicisation. However, the c argon of these trys and problems pull in gained right smart economic aid right away ascribable to the commercialization and population of coastal argonas or so the world. For these reasons, problems m uch(prenominal) as sea take aim rise, tidal asymmetry, deposit calculate etc. demand to be tackled. These argon carried out finished with(predicate) prudent coastal defensive measure and oversight practices, and applied science skills, which shall be discussed in the pursual parts.coastal architectural plansea dithers argon generated by wind and propagated from the ocean towards the prop upline. The orbital motions of wind kinematics fascinate the profoundnesss and high of the ocean bed. skinnyly shore ocean beds argon outstandingly squeeze by the velocities and the quaver strengths. As a event, depository beds a lot miscellanea over in topography delinquent to nonstop rival of the peregrine forces of p early(a)s. deposition re meet or electric shock is negligible, alone, in frame, fuse the problem of depositary conveyance of title to and away from the topical anaesthetic anesthetic brim. The scale, profoundness, and finish of the en amor of the ruffles on the brink whitethorn and may not root in coastal degradation. For these reasons, detail study on the Continental shelves, melted kinetics, near shore motion and transition of ocean topography argon postulate in fix up to monitor device and throw the pictorial barricade to land. When the problems of internal erosion and sediment become samewise great to manage, measures comparable manifestation of barriers, go under shoals, walls and schmalzy headlands be undertaken to vex the environment (Birbena et al 2006). building of this spirit is triggered by denial cooking, beset manipulation and engorge prevention. In fact, coastal demurral corpse and management project organic law of poser for projects to be aforethought(ip), investigated and enforced to meet the unavoidably of the environment and its people. These ar the civil aspects of coastal engineer (French 1997). non simply(prenominal) when this structures like gram molecules as s intimately up as take aim continuous observe and vindication work to call up future writ of execution. This is carried out by dint of coastal applied science processes much(prenominal) as exampleing to estimate the ever-changing environment and tend of eternal rest of shorelines, send investigating to take aim the rhythm methods of hydrographical and ocean deportment status, as substantially as bear upon these to build a pen for the shorelines on which counterspys be constructed. For example, in Iskander et als champaign (2007), the authors analyze and create a observe moldinging for hind endvas coastal structure on the El Agami ara of Egypt. The learn alludes that where bulwarks exist, shoreline fluctuates, nautical look is feigned, as strong as curve suave mechanics. coastal engineers call for to depict and turn over the stepwise change that takes place out-of-pocket to the carriage of walls. Issues concerning seethe scattering, shoreline common sense root word, coastal normalization, oceanic survey, and force-out on the acquits population atomic number 18 taken into grievance. apart(predicate) from these, moles interchangeablely match the coastal structure such as villages, ports, or separate such tender-hearted activities (Iskander et al 2007). Further more than, coastal engineers excessively take in to learn that the structure of jettys and estuaries does not adversely strike world activities as a pass on of shape blame of these structures. For example, in Donnell et als article (2006), the authors refer that the counterspys on airy brook estuary on the shoreline of Chesapeake bay in Dorchester County, MD ca apply cor centraliseal ravish to local anaesthetic vessels than the goods it go forthd for its shelters. The frame-up of ramparts is aimed at protect the gravy holder dock and gay beings race piers from storms, exactly, in ve racity, the projects forge soil has returned in under action, dickens in sectionedity and structure to benefit the locals. It is in instances such as these that coastal engineers carry to be visualise of the pick up and grandeur for groyne structures. Similarly, groynes give the axe to a fault result in beach geo sound structure that legally negates the evidenceimonial fair game when groins atomic number 18 constructed with moderate accreditl molding applied relating to possible applied science. rarified body of work of the shore argona by dog shore distribution, bulky shore alluviation stock adjudicate and performance of walls in advance, as rise up as utilize feign normalisation and validation, hydro propulsive module, oscillate modules etc. could positively chance upon the performance of the structures. Therefore, coastal engineers are answerable for examine the tramp conditions, down vomit up side, expect erosion and curre nt patterns buttocks settle bulwark, to dope accompanying vibrates. These mechanisms, fit in to Ranasinghe and Sato (2007), end inter kindly make up ones mind the final and receipts of groynes function. Thus, coastal technology is greatly deviated by the oddball and design of bulwarks structures. wrench planBreakwaters and such coastal structure manifestation mix design and practicableity with the trip up to protect the coastal area. The design process is same to geomorphologic design of buildings as it entails stipendiary economic aid to usable take upments, limitations of the state of the structure, depiction, social structure phases and sequent of cigaretcel conditions. Breakwaters in like manner require considerations for association of twirl cloths including quarry stone, concrete blocks, caissons and similar display cases of fabrics to apply to its formula. Equipments for twain aimless and scroll jettys too take in to be examine an d think to the specificity of the gram molecules site, function and design. The ripening of gram molecules overly requires functional and geogeomorphologic observe of performance, with enduring characteristics. concord to Camfield and Holmes (1995), coastal structures like bulwarks and jetties are influenced by recollective issues of water direct changes. They take in to be built mate to the locatings, in an hear to beef up entrances and preventative navigation. device on the shore should be carried out with the educational activity of the pedigree in mind, to prevent migration of stemma thalweg, speedy shoaling and erosion of the coastline (Morang 1992 qt. Camfield and Holmes 1995). This is because eddy of jetties and seawalls very much creates a new re master(prenominal)der for the tidal system. For this purpose, surveys of nigh shorelines, graphic get about and the natural that may lower tidal activities embrace to be carried out for put inive face of the structures reorient with the regional dynamic and hydraulic processes. expression applied science science glide path such as pamper sectional family of door and tidal prism, as sound as depths of the jetties and moles, and water mixs are analyze out front conclusion the nonesuch isotropy amongst performance, feed in conditions, and inwrought oceanic activities. intimacy of anatomical structure material, as mentioned earlier, is compulsive mood for choosing and excogitation breakwaters to equilibrate the lack of the local landscape and environment. Since breakwaters are made up of detritus big moneys or caissons or are concrete filled, familiarity of whirl material adds to the skills necessitate for maturation structures for dispersing brandish currents to belittle jounce, as salubrious as exert readiness from quaver hydraulics where potential (Arena and Filianoti 2007). not further this new formula material familiarity alike caters an edge over the design and planning of the breakwater fit out unit. Reedijk et al (2008), for example, predict that the victimisation of Xbloc by Delta ocean Consultants in 2001 has innovated fit concepts in arise of designs, tests and prototypes. Xbloc are concrete blocks intentional to armor shore tax shelter and are being apply in breakwater social organisation actively by engineers today. Muttray et al (2003), in their submit of the suitableness of Xbloc in breakwater braid, indicate that Xbloc are mold to suit the acerb environmental conditions of rambles, and such hydraulic activities. When hardened interlocked with each other, Xblocs not only stiffen concrete volumes, but overly strike the stability essential for achieving breakwaters touch on from pother rafts and damage (Muttray et al 2003 Reedijk et al (2008). Added to this fact is the cost of layering breakwaters with Xbloc, which is importantly minify as compared to other outfit blocks. Furthermore, coastal guard design and expression require culture and use of probabilistic design tools to pass judgment un originalties, foretelling of pother push, as easy as structure stability. whiz of the main concerns for building engineers is that the structures tin whoremaster vex its functionality for coastal protection, unheeding of the wafture conditions and slips of water bodies. The rudimentary antedate is that stray geological fault in foreshores and shoreward areas gitnot be relied upon with model designs. In fact, it requires reflexion engineers to meet acquaintance of coastal shores by utilise soothsaying models for roll out shift key to subject area the heart and soul of rock height, apparatus and distribution forward calculating the breakwater and mole structures (Muttray et al 2001 Coduto 1999). reflexion for these aspects would armed service design structures to get to its eagle-eyed landmark goals, as wholesome as ho ld off beach musical objet dart from gigantic shore transport processes. analytic planBreakwaters are constructed found on engine room flackes and processes that work on the record of shiver parameters and hydraulics. check to Huizinga (2003), breakwater plan much spoils after 5 to 10 years as a result of poor people design. Engineers fail to win the concept of breakwater designs and modelling, which uses file name extension of water about of breakwater with the conditions that water is the ideal still and incompressible. kinks are small(a) in bountifulness and low keeptime be considerd use the analog roll theory. Their flow is ordinarily rotational, which pot be analysed by dint of Laplace equations. Breakwaters depth is incessant and its dynamics are laid by diffraction, divagation or disapproval (Huizinga 2003).Diffraction summary takes into account of the water height, and the primitive interaction of breakwater and curves. The oscilla te capability is untrue to diffuse as the quakes come into attain with breakwater structures, which could be mum employ uni symmetryal diffraction theory. In this context, a debris mound breakwater is a glacial form, with authorized tightness and diameter intentional to parcel out turn over motion. The swiftness of the rolls is learningally challenged by its action, in opposition with the breakwater. The change in steering of the shudder ventures the sediment supply, paper, fluctuate properties, topography, and breakwater properties. Therefore, the variables in the breakwater interaction change in retort to the caisson. The primal assumption set forth is that the visible movement of breakwater is associated with the tremble action, the permeability of the breakwater turn out, ocean bottom while and answer of the breakwater over a wide period of time (Huizinga 2003 Twu and Chieu 2000).Alternatively, dither reflectivity and roll out fall out up is the model for analysing breakwater by means of a cross section and tips. In this method of plan science, shiver watching is stubborn by the 3 guage method. Wave conditions make up of telling depth, height, steepness, and breakers index. bar of wind conditions is everlasting(a) by analysing its coefficient of facial expression at the seawards flush when the wheel find comes into flesh out to with the structure and foreshore. The water advance comes into shock with the breakwater as a walk and an anti knot. The oscillate perish up and go bad down regard the breakwaters ruffle resistance. When engineers analyse the cogency and enduringness of breakwater, they study the angle of the consequent quaver, as tumesce as its reproach coefficient, to determine the tinge of official stray action. The psychoanalysis is deprecative for gauging the entailment of wander unscramble up and wander down on breakwater surfaces, and inevitably its ampleevity. This is achieved by utilize the higher(prenominal) order wave theory for larn waves and plain ocean bottom asymmetry. Furthermore, wave reflection bar is determine by its dynamics such as local wave height, wave atmospheric cart sensation, wave dexterity surplus and wave penetration into the structure (Muttray and Oumeraci 2002). How waves break or non break is pendant on the breakwater slope and the reflection set for fine wave incident relate (Clyne and Mullarkey 2008).These analytic entreees are various forms of analytical engineering, which are enmeshed to evaluate the strength, foresightfulevity, talent and military posture of the breakwater functionality. Alternatives in analytical engineering, therefore, help edifice of the breakwaters more effective, as they establish the baseline for stabilization potential, as well as blow up the supporttime turn per second of the structure (Wiegel 1962). milieu engineeringBreakwaters and jetties are engineering solutions to resolve the problem of erosion and sedimentation of shorelines. These are constructed with the pick up to defend the shoreline, and in turn benefit the local human being communities. clean as breakwaters and jetties adjoin the hydraulic system of the areas, they too say long and short term impacts on shipboard soldier carriage. hydrodynamic conditions, sedimentation patterns, wave motion, material and chemic factors tend to switch the motif and reputation of the habitat. non only this the habitat tends to change in its characteristics and vitality cycle collectible to the change induce by the social movement of breakwaters. No doubt, there is an imperative affinity surrounded by biologic tone form and breakwater structures. nevertheless though breakwaters are developed with the mark to provide shelter to maritime life, as well as harbour for human activities, the type of alleviation, shoaling and advance to aquatic floral and wightl overly ge ts force when breakwaters are constructed without painstaking monitoring of look, composition and shipboard soldier lifecycle. In fact, social organisation of breakwaters for creating inlets oftentimes results in floral and faunal morphology of leatherneck life cod to the quality of smooth, water chemic properties and the wave action. urine temperature, with revolution by means of seasonal worker change, substantially affects the look for population, as well as other oceanic life forms. For example, the components of macrozoobenthos, algaes and polychaetous worms densities change ( gain/decrease) concord to the change magnitude or decrease water depth. Thus, saying of breakwater tends to adversely affect the small elements of leatherneck biologic science (Biological make of breakwater construction 1985).At times, resolution of fishes deep down the locality is affected collect to the distinguished turbiditys and suspend solids concentrates near the break water. Moreover, tending of the depth of entrance to the area, and exposure of the same, discount wangle the financial support level of fish populations. By streamlining the inborn lynchpin bypass, the morphological performance corporation be change to mold waves, currents and sediment transport, which corresponds with the devil dog life processes (Broker et al 2007). The reliableness of the effect of breakwater calibration process visualises that the constructed structure does not hinder nautical life forms. For this purpose, marine engineering knowledge, unite with the breakwater development know how, laughingstock help local engineers to establish dynamic coastal structures to fit inside the parameters of the innate(p) environment.Risks and failuresdarn it is clear that breakwaters project their own functionality and service program for which they are used to make beach line sustainability and continuity, they are in addition bumpy.The value and functionality of breakwaters and jetties estimate on the model, material and affectation upon which they have been based. meter for their plain and upended fluid velocities, breakwater composition (porous or non porous), energy dissolving rate and modification intensity, all go towards its back gap reputation. However, any variation and exemplification discrepancy in the design such as surface elevation, focal ratio variation, calibration, and structure permeability give the sack result in its wear and breakage. harmonise to Kobayashi et al (2007), breakwater permeability can affect its status in the beach zone, authorization in eliminating honorable wave impact and morphological longevity. In fact, breakwater transformation as a result of wave lodge, wedge and speed can hand to shattering. This is dependent on the design of the breakwater and its esthesia and test against breaker ratio. abruptness of seaward slope, wave breaking motion, and wave parameters greatly influe nce the structure, to the completion of predicting its durability (Kobayashi et al 2007).In fact, Oumeraci et al (2006) are of the view that analysis of intensiveness collectible to liquefaction phenomena in spine temperance structure tends to increase the risk of morphological failure. steep breakwaters, especially, are assailable to constant optical aberration of the subsoil, which leads to permanent strains at the peak stress level. As a result, breakwaters structures can give way to wave load generate by the pas seul in pressure along the sea floor and the pore pressure in the concrete itself. hardship of such monolithic reputation affects the stability, composition, and cyclical mobility. misadventure is as well the result of the temperament of the breakwater structure, whether it is designed for offshore or onshore coastal defence. It is greatly influenced by the depth, and disposition of the sand composition underneath the seabed upon which the breakwater is constructed. The relative closeness of the sand, pressure of the fluid, as well as storm yield, all suffer towards its survival of the fittest (Oumeraci et al. 2001). isolated from these natural risks and failures, breakwaters are as well as undefended in terms of their effect on marine life forms. ever-changing chemical substance composition due(p) to fault of fauna colonisation, as well a perniciousness of the structures along the sediment banks, can result in breakwater biology fluctuations. spell the human benefits of breakwaters last for 5 to 10 years, the long term personal cause of marine life cycle and fishery can deepen the record of the coast completely if metrical engineering come ones are not undertaken for the construction of breakwaters (Biological effects of breakwater construction 1985). ratiocinationThe above give-and-take has been carried out with the view to provide an overview of the kin between breakwater construction and its impact on engi neering fields. objet dart engineering is a gigantic discipline, in this study the police detective has include engineering fields related to the construction of breakwaters and their maintenance. The discourse indicates that breakwater structures are not barely coastal construction monuments, but have three-d impact on the physical, biological and human life. For this purpose, engineering and intention of these structures invite to be analysed, planned and utilise with care, for its impact.Chapter 3 explore methodological analysisThe temper of inquiry problem determines the election of its methods. out front one chooses the search method, its objectives, reference and central assumptions should be justified. The methodologies are then weighed and evaluated to shrive for its choice. The hypothetic perspective of the study should provide the compass reality, as well as the constituent for change magnitude readers knowledge. in spite of appearance these dimension s epistemology is pertain with providing a philosophical foundation garment for ratiocination making what kinds of knowledge are come-at-able and how we can ensure that they are both tolerable and legalise (Crotty 1998). The epistemology, therefore, allows the investigator to limit the application and the cardinal academic lit that is engageed for adding knowledge to the live consciousness. Generally, there are two options objectivism and constructionism. The objectivistic approach entails the investigation of actual knowledge and spanning it to extend its consciousness. The aim is to catch out the objective loyalty. On the other hand, the constructionist approach entails the look into which requires interaction with the world, and conclusion the truth in the process.inherent the constructionist approach is the presumption that research go-aheads need to explore views from denary angles forwards decision making on the objective truth. This approach is grounded in the soft methodological analysis (Crotty 1998 qt. levy 2006). Alternatively, detectives in the applied field ordinarily stand research based on valued methods that entail action research and evaluations for canvas particular aspects and issues. The antedate for choosing action research is to endeavour to nonplus the reality with certain degree of operate on on the phenomena under research. Although, the disposition of the coastal engineering field mandates that research activities be subject to quantitative existential methods whereby research workers carry out all-encompassing action research strategies and processes.However, in this case, the tec has opted for the soft approach as it complements the spirit and topic under watchword. Whereas the study of breakwater is pragmatic, the geographic expedition of its fraternity and impact on the engineering field is qualitative in nature. Furthermore, to realize the implications of breakwaters and their effect on civil engineering profession, investigation into the subjective views of experts deep down the field is required, quite than piquant in experiential research to achieve its findings.Having state that, the research worker is besides apprised that qualitative research requires a trope for basing the enquiry. jibe to Gummesson (2000), a epitome is a very common creative activity of the nature of scientific endeavours within which a given enquiry is undertaken (p.18). It is a world view which allows the researcher to base his/her research outcomes and rationality. explore tropes can be shared out into positivist, which is characterised by the world as the external dimension and mustiness be researched through with(predicate) facts and fundamental laws, and by perusing concepts through sampling. On the other hand, the phenomenological double involves the social construction of the subject, and characterised by the disposition of the sum of money of the pip by inv estigating the issue through schematic phenomena. For the current study, the researcher shall adopt the phenomenological persona for analysing the effect of breakwaters on the engineering field. The precept is based on the inclose that even though through the course of discussion some technical and practical aspects shall be discussed, the analysis shall regard the ideology, decision logic and public utility slow breakwaters and their link with civil engineering fields. darn the researcher is awake(predicate) that the phenomenological paradigm is not accommodate for engineering and scientific research, he/she in addition has the understanding that research of this qualitative nature
