Abstract:

Abstract. Coastal defences have long been employed to halt or slow coastal erosion, and their impact on local sediment flux and ecology has been studied in detail through field research and numerical simulation. The non-local impact of a modified sediment flux regime on mesoscale erosion and accretion has received less attention. Morphological changes at this scale due to defending structures can be difficult to quantify or identify with field data. Engineering-scale numerical models, often applied to assess the design of modern defences on local coastal erosion, tend not to cover large stretches of coast and are rarely applied to assess the impact of older structures. We extend previous work to explore the influences of sea walls on the evolution and morphological sensitivity of a pinned, soft-cliff, sandy coastline under a changing wave climate. The Holderness coast of East Yorkshire, UK, is used as a case study to explore model scenarios where the coast is both defended with major sea walls and allowed to evolve naturally were there are no sea defences. Using a mesoscale numerical coastal evolution model, observed wave-climate data are perturbed linearly to assess the sensitivity of the coastal morphology to changing wave climate for both the defended and undefended scenarios. Comparative analysis of the simulated output suggests that sea walls in the south of the region have a greater impact on sediment flux due to increased sediment availability along this part of the coast. Multiple defence structures, including those separated by several kilometres, were found to interact with each other, producing complex changes in coastal morphology under a changing wave climate. Although spatially and temporally heterogeneous, sea walls generally slowed coastal recession and accumulated sediment on their up-drift side.

Abstract:

Saltmarshes are considered as natural coastal defences. However, owing to the large context dependency, there is much discussion over their effectiveness in providing coastal protection and the necessity of additional coastal defence interventions. The macro-tidal Taf Estuary in south-west Wales was chosen as the case study in this paper to investigate the effects of anthropogenic coastal defence interventions such as construction of hard defences, managed realignment, and altering land use of the saltmarshes on the complex hydrodynamics of the estuary. A coupled flow–wave–vegetation model, developed using the Delft3D coastal modelling software, was used. The wave and current attenuation role of saltmarshes during two contrasting storm conditions was modelled, with and without saltmarsh management interventions. The study reveals that certain saltmarsh management interventions can have widespread impacts on the hydrodynamics of the estuary. Altering the land use by allowing extensive grazing of saltmarsh by livestock was found to have the largest impact on wave attenuation, where wave heights on the marsh almost doubled when compared with the no-intervention scenario. On the other hand, managed realignment has a significant impact on tidal currents, where tidal currents reached 0.5 m/s at certain locations. Changes in estuarine hydrodynamics can lead to undesired impacts on flooding and erosion, which stresses the importance of understanding the effects of localized anthropogenic coastal management interventions on the entire estuarine system.

Abstract:

The promontory site of Le Yaudet, on the north coast of Brittany, was occupied from the Bronze Age to the present day, at various stages during this period sharing in maritime exchange systems linking Brittany to Britain. In the Late Iron Age the site, of some 6ha, was surrounded by stone and rubble defences the main cross-promontory defence being of murus gallicus type. The defences are of at least two phases, the later probably dating to the time of Caesar. Occupation continued and in the late third century AD a new wall was built around the defensive circuit at a time when similar coastal sites on both sides of the Channel were being defended. On one site, agricultural activity of the early medieval period was followed by village development in the eleventh century. The present village is a shrunken remnant of the earlier, more extensive settlement.

Abstract:

A master plan to strengthen the weak links in the coastal defence line in the Belgium is established based on coastal flooding risk calculations. This plan takes into account an average climate change scenario to be expected in the coming decades until 2050, namely an increase of surge levels of 30 cm. More long term climate change scenarios were also investigated. A worst credible extreme scenario for the 21st century change of the hydrometeorological North Sea climate was defined, with a mean sea level rise of 2 m combined with a 8% increase of extreme wind speeds. Alternative measures to manage coastal flooding risks under such climate scenario were studied to find robust measures to adapt coastal protection to climate change until 2100. The Belgian coastal zone is low-lying, highly populated and it is very vulnerable to increased coastal flooding risks by climate change. The methodology for the coastal flooding risk calculations is based on a chain of numerical models describing characteristics of storm surges with different return periods approaching the coastal defences, the failure behaviour of these defences, the hydraulics of flooding in case of failure by breaching, overflow or overtopping of the defences and finally a GIS-based damage and casualties module adopted for use within Flanders region based on available detailed GIS-data on people and assets. The rate of increase of coastal flooding risks for different climate change scenarios is quantified using a simplified version of the chain of models described above. This generalised model chain was validated by comparing with the results of the detailed model chain for the anno 2000 case. However, flooding paths via the coastal harbours as well as local risks on top of the sea dikes in the coastal towns were disregarded in the simplified model. As a consequence the results on climate change sensitivity are limited in scope to the risks associated with breaching of the sea dikes and dunes. The calculation results show a dramatic increase of the coastal flooding risks due to breaches during 21st century. For an average climate change scenario, with an increase of surge levels by 0.8 m, the risks increase by a factor 10. For the worst credible climate change scenario, with an increase of surge levels by 2.4 m, the risks increase by a factor 100. Existing coastal defences in the Belgian coastal zone are relatively low-crested compared with surge levels. This fact increases the vulnerability of this coastal zone to climate change, as was shown by the coastal flood risk calculation results. Different adaptation measures to manage these increasing risks were compared. Based on their effectiveness to reduce risks as well as estimates of costs for implementation it was concluded that efficient adaptation measures consist of heightening and/or widening the existing dunes, sea dikes and beaches. Future research will investigate which adaptation measures can be developed in the coastal harbours for maintaining safety against flooding under climate change.

Abstract:

Terms such as 'nature-based', 'living shoreline', 'green infrastructure' and 'ecological engineering' are increasingly being used to reflect biomimicry-based engineering measures in coastal defences. Innovative interventions for nature-based sea defences have included the retrofitting of man-made water filled depressions or 'vertipools' to existing seawalls (Hall et al., 2019; Naylor et al., 2017) and the addition of artificial drill-cored rock pools to intertidal breakwaters (Evans et al., 2016). Through their capacity to retain water, such measures serve to enhance biodiversity in the built environment (Browne and Chapman, 2014). Evans et al. (2016) for example, experimentally demonstrated that the introduction of artificial rock pools to an intertidal granite breakwater enhanced the levels of species richness compared to those observed on plain surfaces of the breakwater. Notwithstanding these biological benefits, the impetus for incorporation of ecologically friendly measures to existing defences remains low (Salauddin et al., 2020a). This situation could potentially change should it be shown that the addition of 'green' measures to sea defences could enhance wave attenuation and reduce wave overtopping as well as wave pressures on the coastal defence structures. This paper describes small-scale physical modelling investigations of seawalls and explores reductions in wave overtopping that could be realised by retrofitting sea defences with 'green' features (such as 'vertipools'). Surface protrusions of varying scale and density are used in the physical modelling to mimic 'green' features and the results from measurements of overtopping are benchmarked to reference conditions determined from tests on a plain seawall.

Abstract:

Sea level rise and an increase in typhoon intensity are two of the expected consequences from future climate change. In the present work a methodology to change the intensity of tropical cyclones in Japan was developed, which can be used to assess the inundation risk to different areas of the country. An example of how this would affect one of the worst typhoons to hit the Tokyo Bay area in the 20th century was thus developed, highlighting the considerable dangers associated with this event, and how current sea defences could be under danger of failing by the end of the 21st century.

Abstract:

Wind effects on wave overtopping over fully impermeable vertical sea defence is studied in a shallow water flume based on a physical model for the Livermeade defence system. The investigation is mainly focused on impulse type wave interaction with the sea defence, when the overshooting jet is high during overtopping. We are able to identify distinct types of overtopping flows where moderate wind speed is not found to be affecting uniformly in all cases. We try to find explanation of this behaviours by studying the standing waves at the defence and complementary CFD simulations.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/byRz_N9zoXk

Abstract. This paper provides a comparison of the causes, effects and aftermaths of the coastal flooding that occurred on the east coast of England in 1953 and the west coast of France in 2010 that resulted in 307 and 47 deaths respectively. The causes of both events are strikingly similar. Both were caused by a combination of high tides, low atmospheric pressure, high winds and the failure of poorly maintained flood defences. In both cases the number of deaths was related to the vulnerability of the buildings and people. Buildings in the flood zones were often single storey bungalows and the people who died were mostly over 60 yr of age. Both tragedies were national disasters. The 1953 flood in England acted as a catalyst for an acceleration in flood risk management policy and practice. It resulted in: the development of a Storm Tide Warning System for the east coast of England; the setting of new design standards for coastal flood defences; increased investment in improving coastal defences; and a substantial new research effort into coastal processes, protection and forecasting. In France there has also been an episodic shift in flood risk management policy with the focus falling on: control of urban developments in areas at risk of flooding; improved coastal forecasting and warning; strengthening of flood defences; and developing a "culture of risk awareness". This paper outlines the lessons that can be learnt from the two events and provides recommendations concerning how future loss of life as a result of coastal flooding can be reduced.

Sustainability of coastal areas requires the development of a standard procedure for the selection of equitable defence solutions and the design optimization of existing defences in order to minimize the impact on the environment and maximize positive effects such as species biodiversity and structure colonization. The aim of this paper is to propose a combined method, based on numerical simulations and on collection of ecological data in the field, to provide indications for an environmental friendly construction of breakwaters. This method is applied and tested against the case study of Elmer, UK, where information on existing species and their abundance related to hydrodynamic effects induced by the breakwaters

Abstract:

SUMMARYRealization that hard coastal infrastructures support lower biodiversity than natural habitats has prompted a wealth of research seeking to identify design enhancements offering ecological benefits. Some studies showed that artificial structures could be modified to increase levels of diversity. Most studies, however, only considered the short-term ecological effects of such modifications, even though reliance on results from short-term studies may lead to serious misjudgements in conservation. In this study, a seven-year experiment examined how the addition of small pits to otherwise featureless seawalls may enhance the stocks of a highly-exploited limpet. Modified areas of the seawall supported enhanced stocks of limpets seven years after the addition of pits. Modified areas of the seawall also supported a community that differed in the abundance of littorinids, barnacles and macroalgae compared to the controls. Responses to different treatments (numbers and size of pits) were species-specific and, while some species responded directly to differences among treatments, others might have responded indirectly via changes in the distribution of competing species. This type of habitat enhancement can have positive long-lasting effects on the ecology of urban seascapes. Understanding of species interactions could be used to develop a rule-based approach to enhance biodiversity.

Abstract:

Coastal defences are proliferating in response to anticipated climate change and there is increasing need for ecologically sensitive design in their construction. Typically, these structures support lower biodiversity than natural rocky shores. Although several studies have tested habitat enhancement interventions that incorporate novel water-retaining features into coastal defences, there remains a need for additional long-term, fully replicated trials to identify alternative cost-effective designs. We created artificial rock pools of two depths (12cm, 5cm) by drill-coring into a shore-parallel intertidal granite breakwater, to investigate their potential as an intervention for delivering ecological enhancement. After 18 months the artificial rock pools supported greater species richness than adjacent granite rock surfaces on the breakwater, and similar species richness to natural rock pools on nearby rocky shores. Community composition was, however, different between artificial and natural pools. The depth of artificial rock pools did not affect richness or community structure. Although the novel habitats did not support the same communities as natural rock pools, they clearly provided important habitat for several species that were otherwise absent at mid-shore height on the breakwater. These findings reveal the potential of drill-cored rock pools as an affordable and easily replicated means of enhancing biodiversity on a variety of coastal defence structures, both at the design stage and retrospectively.

Abstract:

The aim of this research is to analyze of DIY coastal landscape with visual preference analysis for suistanble coastal tourism development and management. The unit of analysis that used is coastal typology. The guideline in deciding the classification of coastal typology is using the Response-Process System with relief/slope, main constructing material, genesis process and dominate process happened in the meantime such as tide, wave and river flow. This response-process system divide the coastal typology into seven classes including coastal typology of land erosion coast, sub aerial deposition coast, volcanic coast, structurally shaped coast, wave erosion coast, marine deposition coast and coast built by organism. The method of SBE (Scenic Beauty Estimation) is used for visual preference analysis, and the method used to compose the policy of costal tourism development is SWOT method. Result shows that all seven coastal typology are found in the coastal area. Land erosion coast and coast built by organism dominate in Gunungkidul coastal area and then in Bantul and Kulon Progo coastal area are dominated by marine deposition coast and sub aerial deposition coast. Volcanic coast, structurally shaped coast, wave erosion coast can only be found in a small area of Gunungkidul coast. Each of this coastal typology has a special land characteristic which can be used to develop its potential. Coast built by organism is very suitable for tourism activity proved by the high score of SBE from the respondents. Recommendation for developing coastal area in area of interest is by developing the coastal natural resources suitable to its physical typology, because this will make the management of coastal area for continuous development easier. Recommendations for coastal management in Gunungkidul including mapping and classification of protected karst area and mineable karst area to secure the run of coastal area management, for coastal management in Bantul using Managed realignment which plans for retreat and adopts engineering solutions that recognise natural processes of adjustment, and identifying a new line of defence where to construct new defences and move seaword model by constructing new defenses seaward the original ones. Last, for Kulon Progo coastal area using hold the line model whereby seawalls are constructed around the coastlines.

Abstract:

The Dutch government is in the process of revising its flood safety policy. The current safety standards for flood defences in the Netherlands are largely based on the outcomes of cost-benefit analyses. Loss of life has not been considered separately in the choice for current standards. This article presents the results of a research project that evaluated the potential roles of two risk metrics, individual and societal risk, to support decision-making about new flood safety standards. These risk metrics are already used in the Dutch major hazards policy for the evaluation of risks to the public. Individual risk concerns the annual probability of death of a person. Societal risk concerns the probability of an event with many fatalities. Technical aspects of the use of individual and societal risk metrics in flood risk assessments as well as policy implications are discussed. Preliminary estimates of nationwide levels of societal risk are presented. Societal risk levels appear relatively high in the South Western part of the country where densely populated dike rings are threatened by a combination of river and coastal floods. Options for the application of the individual and societal risk in the new flood safety policy are presented and discussed.

Abstract:

Coastlines are drastically altered globally due to urbanisation and climate-related issues. As a response, communities build coastal defence structures to protect people and property. Although these infrastructures fulfil engineering demands of coastal defences, the trade-off to nature includes a decrease in biodiversity able to live on these structures because of the lack of topographic complexity. Several studies have tried to increase the surface complexity on coastal defence structures through eco-engineering habitat enhancements that mimic nature. However, few of these studies have been conducted in tropical regions where effects are more pronounce due to desiccation and extreme heat. In this study, water-retaining structures (in the form of rock-pools at depths 12 cm, and 5 cm) were drill-cored into coastal defence structures (i.e. granite rock revetments) on reclaimed coastlines in Penang Island, Malaysia. We found greater species richness and an increase in community structure in the drill-cored rock pools regardless of the depth of these artificial rock-pools. Positive habitat selection also occurred within micro-habitats of this scale. The drill-cored artificial rock pools in these tidal exposed revetments also provided niche-spaces for marine organisms found in low-tide or sub-tidal areas. These findings demonstrate the potential of this eco-engineered habitat enhancement as a means of promoting biodiversity on granite rock revetments, which can be applied either during design phase of a coastal development or retrospectively.

Abstract:

In order to quantify the risk of flooding, an integrated risk analysis is being performed within the German ‘XtremRisK’ project (Extreme storm surges at open coasts and estuarine areas: risk assessment and mitigation under climate change aspects) wherein one task is to analyze the reliability and breaching of flood defences. In this paper, the methods and results of the reliability analysis and the breach modelling of sea and estuary dikes and coastal dunes are discussed and applied to examples of the pilot sites of Hamburg (Elbe Estuary) and the Island of Sylt (North Sea). These results are put in context of an integrated flood risk analysis approach used in XtremRisK.

Abstract:

Introduction The German Federal State Lower Saxony borders on its northern side the southern North Sea. The coastal low¬lands of Lower Saxony represent an important eco¬nomical, agricultural, cultural and ecological area. About 6,600 km² with 1.2 million inhabitants are flood prone by storm surges. The main coastal defence elements on the mainland coast are main dikes and storm surge barriers. In case of main dikes, on significant stretches of the coastline additional protection elements such as dike forelands and sec¬ond¬ary dike lines are present. Aspects of flooding due to failure of coastal defences and the consequences are investigated by the Lower Saxony Water Management, Coastal Defence and Nature Conservation Agency (NLWKN) within two research projects SAFECOAST and HoRisK (Flood Risk Management for Coastal Areas) in order to facilitate technical aspects of the EU Flood Risk Management Directive’s implementation. Objectives and methods Within subproject HoRisK-C ‘Consequences of Flooding at the North Sea Coast’ led by NLWKN, hydrodynamic flooding simulations are performed for selected boundary conditions and failure scenarios of the coastal defence system. Aims of the investigations are damage and risk assessments as well as methods to reduce damages and risks. In order to estimate the damages the Source-Pathway-Receptor approach is adopted. The sub¬project HoRisK-C focuses mainly on the latter aspects. A hydro¬dynamic model and a geo¬graphical information system (GIS) are used to determine flood pro¬pagation, water depth and resulting damages. The results of the investigations conducted in SAFECOAST delivered significant influences of topo¬graphical elements such as drainage systems, positive break lines and small variations of elevation on the simulated inundation. Taking these findings into account, main objectives of HoRisK-C are investigations regarding the con¬se¬quences of failure for coastal lowlands protected by different coastal defence systems. Therein included are the influence of specific defence elements and topography on flood propagation and extension. In a further phase of the project the findings will be integrated in options to reduce exposure of receptors and risks in flood prone coastal areas. First results For the pilot site ‘Norden’ hydrodynamic simulations of a dike failure scenario using a 50x50 m terrain model, a uniform 150 m breach width and a drainage system yield flood extension and maximum water depth. Calculations are conducted for the existing coastal defence system consisting only of a main dike as well as for two modified systems based on this existing. One modified system represents a theoretical foreland whereas the other is a combination of the theoretical foreland and a summer dike, i.e. a small dike with crest height of NN + 3.0 m in front of the main dike line. The simulations confirmed the former findings concerning numerical implementation of drainage systems and breach scenarios. Conclusions The hydrodynamic simulations show, that in comparison of a coastal defence system ‘dike without foreland’ a system ‘with foreland’ or ‘with foreland and summer dike’ will reduce the inflow volume as well as the flooded area, significantly. The foreland in front of dikes is subject of the Lower Saxony Dike Law and the Lower Saxony Master Plan Coastal Defence. There its functionality to protect the dike by reduction of the loads, e.g. currents, is addressed. The effect of reducing the inflow volume through a breach in case of a failure of the coastal defence system was shown for selected synthetic and real cases. As a consequence a foreland of sufficient height and width can reduce the consequences for the hinterland and should be taken into account for flooding calculations.

Abstract:

Artificial coast protection is required where coasts are subjected to erosion. Where the country is low it will be necessary to build sea-walls where natural protection by dunes is not adequate or is completely lacking. In both cases it may also be necessary to protect the country from further advance of the sea by the construction of groynes and breakwaters where lateral currents cause displacement of granular shore material. From the study of the history of coast lines and the development of their protection it is apparent .that apart from the necessity of construction the governing factors of the constructions are safety and economy, or as the British "Departmental Committee on Coastal Flooding" states in its Terms of Reference, it has "to consider what margin of safety for sea defences would be reasonable and practicable having regard on the one hand to the estimated risks involved and on the other to the cost of protective measures". New methods of approach and execution of technical problems such as improved methods of observations and measurements, the use of laboratory experiments, availability of modern equipment and new materials open a wide scope for more economic construction. On the other hand, however, development in this field has been comparatively slow because the consequences of failures oblige the responsible engineer only to alter the traditional design step by step in accordance with progress made in the scientific analysis of the destructive forces of waves and of the properties of the new building materials. The need for investigation is sometimes accentuated by a disaster such as was recently caused by the storm surge of January/February 1953 when on the East Coast of England the observed height of the water-level reached a record of 6 ft. or more than the predicted height according to the astronomical conditions for a continuous period of 15 hours as against 5 hours for former surges. In Holland a water level of 75 cm« above the highest ever recorded level was reached on some sea-walls, causing overtopping of waves. Reports by the "Delta Commissie" in Holland and the "Waverley Committee" in England as well as Papers read on the North Sea Floods for The Institution of Civil Engineers, London, and the Koninklijk Instituut van Ingenieurs, The Hague, deal with the subject adequately. In dealing with coast defence schemes it should be borne in mind that for low lying countries designs should not only be limited to artificial works for direct protection of beacheis, sea walls and dunes. Consideration should also be given to works for reducing areas liable to flooding by overtopping of or breaches in sea-walls or by damage to dunes. In such instances a "second line defence" can be usefully suggested with cross banks to divide the areas in bays or compartments. If these cross banks carry access roads,connecting the inland centres with the sea defence works, they will certainly facilitate communications before and during storms and operations for restoring conditions after storms. In all these works bitumen can be applied to advantage for the protection of beaches, sea walls, dunes and banks as well as for road construction and maintenance works. The use of bitumen in coastal engineering is, of course, also based on practice and theory gained from other civil engineering fields, such as road construction and the building industry. The properties of bitumen and bituminous compounds have first been gradually developed to their present standards in these fields and this knowledge has facilitated the scientific and practical approach of the application of bitumen in sea defence works. In this paper the problem is only described from a practical point of view. After dealing with various aspects of the design of coastal works pertaining to the use of bitumen, a short review is given of the most important types, methods of application and properties of bituminous constructions and finally a number of representative examples of each of the types of application is given.

Abstract:

Climate change impacts, sea level rise, and changes to the frequency and intensity of storms, in particular, are projected to increase the coastal land and assets exposed to coastal erosion. The selection of appropriate adaptation strategies requires an understanding of the costs and how such costs will vary by the magnitude and timing of climate change impacts. By drawing comparisons between past events and climate change projections, it is possible to use experience of the way societies have responded to changes to coastal erosion to inform the costs and selection of adaptation strategies at the coastal settlement scale. The experience of implementing a coastal protection strategy for the Gold Coast’s southern beaches between 1964 and 1999 is compiled into a database of the timing, units, and cost of coastal protection works. Records of the change to shoreline position and characteristics of local beaches are analysed through the Bruun model to determine the implied sea level rise at the time each of the projects was completed. Finally, an economic model updates the project costs for the point in the future based on the projected timing of sea level rise and calculates a net present value (NPV) for implementing a protection strategy, per km, of sandy beach shoreline against each of the four representative concentration pathways (RCP) of the Intergovernmental Panel on Climate Change (IPCC) to 2100. A key finding of our study is the significant step-up in expected costs of implementing coastal protection between RCP 2.6 and RCP 8.5—from $573,792/km to $1.7 million/km, or a factor of nearly 3, using a social discount rate of 3%. This step-up is by a factor of more than 6 at a social discount rate of 1%. This step-up in projected costs should be of particular interest to agencies responsible for funding and building coastal defences.
