The potential impacts of sea level rise along the coastal zone of Kanyakumari District in Tamilnadu,India

Climate change associated with sea level rise (SLR) is one of the major environmental concerns of today. This paper presents an assessment of the impacts of sea level rise on the coastal zone of Kanyakumari District in Tamilnadu, India. Digital Elevation Model (DEM) combined with overlay techniques in GIS are used in determining the inundation zones along the coastal region. The analysis evaluated the impact on coastal fishing villages, landuse, tourist spots and sensitive areas under threat. The vulnerability of the coastal areas in Kanyakumari to inundation was quantified, based on the projected sea level rise scenarios of 0.5 and 1 m. Our findings reveal that approximately 13 km² of the land area of Kanyakumari would be permanently inundated due to SLR. This would result in loss of land, alteration of the coastal zone and affects coastal ecosystem. From the study, the mitigation measures (engineering measures) and Coastal Zone Management practices that can be taken to protect human life and property from sea level rise are suggested.     

Spatial assessment of sea level rise on Martinique’s coastal zone and analysis of planning frameworks for adaptation

Accelerated sea level rise and hurricanes are increasingly influencing human coastal activities. With respect to the projected continuation of accelerated sea level rise and global warming one must count with additional expenses for adaptation strategies along the coasts. On the mountainous island Martinique the majority of settlements are situated along the coast almost at sea level. But potential rises in sea level and its impacts are not addressed in coastal management, even though saltwater intrusion and coastal erosion with increasing offshore loss of sediment are locally already a severe problem. At a sea level rise of 50 cm, one fourth of Martinique’s coastline will be affected by erosion and one fifth of the islands surface will have high probability to get flooded during coastal hazards. This is a growth of 5% of the impact area in comparison to present conditions. This article analyses potential adaptation strategies and argues that the development of a coastal zone management plan considering sea level rise and its impact area is of utmost importance. Empirical assessment models in combination with spatial analysis are useful in obtaining statements about coastal impacts concerning sea level rise. This paper sees itself as recommendation of action not only for Martinique.

Awareness of sea-level response under climate change on the coast of Ghana

In response to climate change, coastal communities are expected to experience increasing coastal impacts of sea-level rise (SLR). Strategies formulated and implemented to curb these impacts can thus be more effective if scientific findings on the response to climate change and SLR impacts on coastal communities are taken into consideration and not based merely on the need for coastal protection due to physical coastal erosion. There is also the need to determine the level of awareness of sea-level rise and responses in coastal communities to improve adaptation planning. This study assesses the impact of future erosion on the coastal land cover of Ghana. This assessment estimates approximately 2.66 km², 2.77 km², and 3.24 km² of coastal settlements, 2.10 km², 2.20 km² and 2.58 km² of lagoons, 1.39 km², 1.46 km² and 1.71 km² of wetlands to be at risk of inundation by the year 2050 based on coastal erosion estimates for the 2.6, 4.5 and 8.5 Representative Concentration Pathways (RCPs) used in the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC). This study also assesses the level of awareness of respondents to SLR on the coast of Ghana and explores the availability and level of integration of scientific knowledge of SLR into coastal adaptation strategies in Ghana. Assessment of the awareness of SLR responses to the changing climate in Ghana is made through semi-structured interviews at national, municipal/district and coastal community scales. Although settlements may be inundated based on the coastal erosion estimates, coastal dwellers interviewed cherish their proximity to the sea and are determined to maintain their occupancy close to the sea as spatial location influences their source of livelihood (fishing). Respondents lack knowledge/understanding of SLR, as the majority of household interviewees attributed the rise or fall in sea level to God. Respondents from Ngiresia alleged that the ongoing coastal sea defence project in their community has led to increased malaria cases.     

National assessment of coastal vulnerability to sea-level rise for the Chinese coast

Sea-level rise as a result of climate change increases inundation and erosion, which are affected by a complex interplay of physical environmental parameters at the coast. China’s coast is vulnerable to accelerated sea-level rise and associated coastal flooding because of physical and socio-economical factors such as its low topography, highly developed economy, and highly dense population. To identify vulnerable sections of the coast, this paper presents a national assessment of the vulnerability of the Chinese coast using 8 physical variables: sea-level rise, coastal geomorphology, elevation, slope, shoreline erosion, land use, mean tide range, and mean wave height. A coastal vulnerability index was calculated by integrating the differentially weighted rank values of the 8 variables, based on which the coastline is segmented into 4 classes. The results show that 3% of the 18,000-km-long Chinese coast is very highly vulnerable, 29% is highly vulnerable, 58% is moderately vulnerable, and 10% is in the low-vulnerable class. Findings further reveal that large amounts of land and population will be vulnerable to inundation by coastal flooding from sea level rise and storm surge. Finally, some suggestions are presented for decision makers and other concerned stakeholders to develop appropriate coastal zone management and mitigation measures.     

GIS-based risk assessment for the Nile Delta coastal zone under different sea level rise scenarios case study: Kafr EL Sheikh Governorate, Egypt

Sea level changes are caused by several natural phenomena, including mainly ocean thermal expansion, glacial melt from Greenland and Antarctica. It was estimated, in this respect, that global average sea level rose, during the 20th Century, by at least 10 cm. This trend is expected to continue and most likely accelerated during the 21st Century due to human-induced global warming. Global average sea level is expected to rise, by the year 2100, due to global warming between 0.18 and 0.59 cm. Such a rise in sea-level will significantly impact coastal areas due to the high concentration of natural and socioeconomic activities and assets located along the coast. The northern coastal zone of the Nile Delta is generally low land, and is consequently vulnerable to direct and indirect impacts of sea level rise (SLR) due to climate changes, particularly inundation. Despite the uncertainty associated with developed scenarios for climate change and expected SLR, there is a need, according to precautionary approach, to assess and analyze the impacts of SLR. Such an assessment, on one hand, can assist in formulating effective adaptation options to specific, sometimes localized, impacts of SLR. On the other hand, such an analysis can contribute significantly to the development of integrated approach to deal with the impacts of SLR. The objective of this paper is to assess and spatially analyze the risks of expected sea level rise (SLR), in particular inundation, and its implications up to the year 2100 in Kafr El Sheikh Governorate, Egypt, using GIS techniques. For that purpose, a GIS was developed for the study area and then utilized to identify the spatial extent of those areas that would be vulnerable to inundation by SLR. Moreover, various land uses/land covers susceptible to such inundation were identified. Results indicate that more than 22.59 % and 24.50 % of the total area of Kafr El Sheikh Governorate would be vulnerable to inundation under B1 and A1FI (IPCC most optimistic and pessimistic scenarios), respectively. No significant difference was noticed between the two scenarios in terms of spatial extent of SLR impacts. It was also found that a significant proportion of these areas were found to be currently either undeveloped or wetlands. Moreover, it was found that about 90.13 % of the vulnerable areas are actually less exposed to the risks of SLR due to the existence of a number of man-made features, not intended as protection measures, e.g. International Coastal Highway, that can be used to limit the areas vulnerable to inundations by SLR.     

Riding the storm: the response of Plantago lanceolata to simulated tidal flooding

Supra-tidal plant communities fulfil a vital role in coastal protection and conservation but despite an increased likelihood of salt-water inundation from storm surges, we understand remarkably little on how salinity affects habitats like coastal grasslands or their component species. We quantified the survival and growth of a common coastal grassland plant, Plantago lanceolata when exposed to short-duration (1-, 2-, 4-, or 8-h) immersion in sea water. We also calculated root:shoot ratios (R:SR) and specific leaf area (SLA) to examine how salinity stress affects above- and below-ground resource allocation patterns and likely interactions with other trophic levels. Immersion in sea water reduced Plantago survival particularly at longer durations of 4- and 8 h, and for surviving plants, growth was also much reduced. Contrary to studies with crop plants however, we found reduced allocation to root biomass (R:SR) and increased SLA. The fact that Plantago displayed opposite ecophysiological responses to those consistently reported in the literature highlights that the response of coastal grassland plants to storm surge events cannot be assumed from conventional wisdom. In order to better protect and conserve these internationally important ecosystems from the effects of anthropogenically induced sea-level rise, a systematic exploration of the effects of sea water flooding on coastal grasslands is required.     

Physical planning in the coastal region of Zeeland, the Netherlands

The Dutch province of Zeeland is situated in the southern part of the Delta region. The geographical location of the province and its history of inundation, land reclamation and dam-building, clearly illustrate the importance that water always has had and still has in The Netherlands. Coastal defence projects are of utmost importance for The Netherlands and the Delta Project is the crown project. The importance of this project does not only regard the protection against the sea; the Delta dams also contribute considerably to the regional infrastructure. They are a important contribution to the abolishment of the former isolation of the region. They control inland navigation and form important boundaries for water management. They separate salt, brackish and fresh water as well as waters with or without tidal-influence and they also influence the ecological systems in and along the waters. Through physical planning, including the coastal policy of today, land and water can be further integrated. This paper discusses the role of the Province in area planning, related to the division of labour between the various public authorities in The Netherlands: state, provinces and municipalities. Coastal and water policy at the provincial level have been largely integrated with relevant other interests. It may be concluded that regional planning and coastal policy are beginning to adopt a new view towards dealing with water.     

Ecosystem service value losses from coastal erosion in Europe: historical trends and future projections

Coastal zones experience increased rates of coastal erosion, due to rising sea levels, increased storm surge frequencies, reduced sediment delivery and anthropogenic transformations. Yet, coastal zones host ecosystems that provide associated services which, therefore, may be lost due to coastal erosion. In this paper we assess to what extent past and future coastal erosion patterns lead to losses in land cover types and associated ecosystem service values. Hence, historical (based on CORINE land cover information) and projected (based on Dynamic and Interactive Vulnerability Assessment - DIVA - simulations) coastal erosion patterns are used in combination with a benefits transfer approach. DIVA projections are based on regionalized IPCC scenarios. Relative to the period 1975–2050, a case study is provided for selected European coastal country member states. For historical (1975–2006) coastal erosion trends, we observe territory losses in coastal agricultural, water body and forest & semi-natural areas – total coastal erosion equaling over 4,500 km². Corresponding coastal ecosystem service values decrease from about €22.3 billion per year in 1975 to about €21.6 billion per year in 2006. For future (2006–2050) coastal erosion projections, total territory losses equal between ~3,700 km² and ~5,800 km² – coastal wetland areas being affected most severely. Corresponding coastal ecosystem service values decrease to between €20.1 and €19.4 billion per year by 2050. Hence, we argue that the response strategy of EU member states to deal with coastal erosion and climate change impacts should be based on the economic as well as the ecological importance of their coastal zones.     

As the world warms: rising seas, coastal archaeology, and the erosion of maritime history

The human history of coastal regions around the world has been under assault for decades, from forces that include dam building, coastal modifications, the destruction of wetlands, marine erosion, population growth and rampant development, looting, and other processes. Global warming will exacerbate the destruction of cultural resources in coastal zones through accelerated sea level rise, intensified storm cycles, and related coastal erosion. Although average global sea levels have been rising for ∼20,000 years, they slowed dramatically about 7,000 years ago. Rates of sea level rise now appear to be increasing rapidly due to growing anthropogenic emissions of carbon dioxide and other greenhouse gases. Global warming and rising seas, especially when combined with population growth and the implementation of measures designed to protect endangered coastal properties, threaten the deep maritime history of human migrations, settlement, and adaptations in coastal areas around the world. Ranging in age from the mid-Pleistocene to recent historic times, coastal archaeological sites contain invaluable data on ancient coastal societies, fisheries, and ecosystems. Archaeologists, historians, and other cultural resource managers must do more to anticipate, evaluate, and mitigate the effects of global warming, sea level rise, and coastal erosion on the long history of human maritime cultures.     

A ‘coastal-hazard GIS’ for Sri Lanka

Following the 2004 tsunami disaster in Sri Lanka, it was apparent that mapping the coast’s vulnerability was essential for future protection of the local populations. We therefore developed a prototype ‘Coastal-hazard GIS’ for Sri Lanka so as to provide an effective tool for decision makers to limit the impact of natural coastal hazards such as sea level rise, tsunamis, storm surges and coastal erosion, and thus protect the exposed assets (population, property, settlements, communications networks, etc.). The prototype was developed on a pilot site in Galle through building up homogeneous data on the land/sea interface from studies conducted on the exposure of the coastal populations, the aim being to enable an evaluation of the hazards combined with the vulnerability and thus an analysis of the risks. Coastal risk scenarios are developed so as to estimate the impacts and consequences of an event (tsunami, storm, etc.) on the assets, the principle behind this being that if, in general, the coastal hazard cannot be decreased, then a better knowledge of it through simulation should make it possible to limit the vulnerability and thus the risk. The Coastal-hazard GIS will also provide a planning tool in terms of locating new settlements, expanding urban areas, siting coastal protection works, etc.     

Coastline management in The Netherlands: human use versus natural dynamics

The boundary between land and sea in The Netherlands changes continuously. Every kilometre of the present position of the Dutch sandy coastline is the result of the interface between natural dynamics initiated by the sea and man-made action on land. Before 1990, each year ca. 20 ha of dunes disappeared through coastal retreat. In 1990 the Dutch government decided to stop any further long-term coastal recession and chose for ‘dynamic preservation’, which primarily aims, at ensuring safety against flooding and sustainable preservation of the values and interests attached to the dunes and beaches. Five years later, a first review of the benefits and bottlenecks of the new coastal defence policy could be presented. The overall conclusion is that the 1990-choice for dynamic preservation was right. The considerable losses of dunes and beaches do not occur any longer. Sand nourishment is an effective method of coastline maintenance, which also serves the functions of the beach and dune area for human society. However, serious erosion of the deeper part of the shoreface threatens the coastline of the 21st century. Nearly a doubling of the nourishment volume is necessary to prevent a renewed landward shift of the coastline. An anticipated accelerated sea level rise (ca. 60 cm/century) will increase the sand losses by another 25%. Plans are being finalized for large-scale land reclamation in front of the coastline as an answer to growing spatial problems on land. In other plans polders, now safely protected by sea dikes, will be returned to the sea in order to restore ecologically valuable salt marshes and mud flats. The position of the coastline will continue to change in the coming decades. Besides natural dynamics, human use of the coastal zone will certainly affect this process: measures to maintain the coastline at its 1990 position need to be seen in perspective: the coastline as a part of the coastalzone.     

Preserving the maritime cultural heritage of the Mediterranean,a cradle of cultures,religions and civilizations—the holy land perspective

The article presents the main ancient marine sites of the Holy Land, points the endangered sites and the needed preservation activities. The ancient cultural heritage existing on the Mediterranean shores reflect important events in the history of humanity. It represents numerous important cultures, religions and traditions. This coastal and underwater heritage is rapidly eroded due to sea level rise, global changes and rapid coastal development. Actions taken by the state of Israel to rescue, protect and preserve the marine cultural heritage include: underwater rescue surveys, coastal erosion monitoring, risk assessment surveys and pilot projects for protecting and preserving the sea front of the antique sites at Akko, Apollonia and Ashkelon. Israel proposes that the Mediterranean and European countries will establish a collaborative project aimed at mapping the cultural recourses and establishing master plans for the protection and preservation of the marine and coastal cultural heritage of the Mediterranean.     

Predicted effects of climate change,vegetation and tree cover on dune slack habitats at Ainsdale on the Sefton Coast,UK

Dune slack habitats are highly dependent on the availability of water to support flora and fauna. Typically this is provided by shallow groundwater. This paper describes the seasonal and long term variation in groundwater levels in part of the Sefton coastline between 1972 and 2007. The effects of climate change, vegetation management and coastline realignment on groundwater levels are modelled. The observed annual water table levels rise and fall with an amplitude of 1.5 m, but longer term variations and trends are apparent. A stochastic water balance model was used to describe the changes in water table levels in slack floors in the open dunes and also in areas afforested with pine trees. It was found that the pine trees evaporated 214 mm/year more than open dunes vegetation, resulting in the water table being 0.5–1.0 m lower under the trees than under the open dunes. The effects of climate change on the ground water was simulated using predictions of future climate conditions based on the UKCIP02 medium high emissions scenario. The increase in temperature and change in rainfall patterns will result in a decrease in mean ground water levels by 1.0–1.5 mm in the next 90 years. Typical patterns consist of sequences of 5–10 years of low water table levels interspersed by infrequent sequences consisting of 2–5 years of relatively high or “normal” levels. These results indicate that that flora and fauna that cannot survive a 5–10 year period of water table levels >2.5 m below ground level are unlikely to survive or persist in many slack areas and a change in the ecology of these slack may become inevitable. Other effects of climate change include sea level rise which will result in a gradual rise in water table levels. Coastal erosion will increase the water table gradient to the sea and result in a slight lowering of the ground water levels. Conversely coastal accretion will reverse this process. The spatial distribution of coastal erosion and accretion along the Sefton coastline and its likely impacts on groundwater levels are discussed. The modelling work described in this paper has identified the factors which have the largest effect on groundwater levels in temperate coastal dune systems.     

Generic framework for meso-scale assessment of climate change hazards in coastal environments

This paper presents a generic framework for assessing inherent climate change hazards in coastal environments through a combined coastal classification and hazard evaluation system. The framework is developed to be used at scales relevant for regional and national planning and aims to cover all coastal environments worldwide through a specially designed coastal classification system containing 113 generic coastal types. The framework provides information on the degree to which key climate change hazards are inherent in a particular coastal environment, and covers the hazards of ecosystem disruption, gradual inundation, salt water intrusion, erosion and flooding. The system includes a total of 565 individual hazard evaluations, each graduated into four different hazard levels based on a scientific literature review. The framework uses a simple assessment methodology with limited data and computing requirements, allowing for application in developing country settings. It is presented as a graphical tool—the Coastal Hazard Wheel—to ease its application for planning purposes.     

River inflow, estuarine salinity, and Carolina wolfberry fruit abundance: linking abiotic drivers to Whooping Crane food

The supply of freshwater to estuarine ecosystems is a critical factor in maintaining the overall health and organization of coastal marshes. Specifically along the Texas Gulf coast, the coupled effects of decreased freshwater inflows to the estuary and natural processes (e.g., precipitation, wind, and tides) can exert significant salt-stress on coastal marsh vegetation. In this project we sought to quantitatively link the inflow of freshwater to the estuary (San Antonio Bay) with Aransas National Wildlife Refuge (ANWR) coastal marsh salinity and assess the influence of salinity and inundation on Carolina wolfberry (Lycium carolinianum Walt.) phenology (leaf and fruit abundance). The Carolina wolfberry is one of the more common high marsh plant species found at ANWR and has been shown to be a key food source for endangered Whooping Cranes which inhabit the coastal marshes of the ANWR each fall/winter. Results from our study show that periods of decreased freshwater inflows to the estuary correlated with increased marsh salinity at the ANWR. Wolfberry plants at ANWR marsh sites displayed increased fruit abundance during years which had lower mean summer time salinity (June, July, and August) in San Antonio Bay; conversely, during years of increased bay salinity during the same summertime months, wolfberry plants showed decreased fruit abundance. Through the continued validation of the relationship between inflows and coastal marsh salinity, we hope to provide additional insight into how wolfberry phenology varies inter-annually across both salinity and inundation regimes and how freshwater inflows may affect food availability for the endangered Whooping Crane.     

Predicting the Impact of Sea-Level Rise on Caribbean Sea Turtle Nesting Habitat

Abstract:  The projected rise in sea level is likely to increase the vulnerability of coastal zones in the Caribbean, which are already under pressure from a combination of anthropogenic activities and natural processes. One of the major effects will be a loss of beach habitat, which provides nesting sites for endangered sea turtles. To assess the potential impacts of sea-level rise on sea turtle nesting habitat, we used beach profile measurements of turtle nesting beaches on Bonaire, Netherlands Antilles, to develop elevation models of individual beaches in a geographic information system. These models were then used to quantify areas of beach vulnerable to three different scenarios of a rise in sea level. Physical characteristics of the beaches were also recorded and related to beach vulnerability, flooding, and nesting frequency. Beaches varied in physical characteristics and therefore in their vulnerability to flooding. Up to 32% of the total current beach area could be lost with a 0.5-m rise in sea level, with lower, narrower beaches being the most vulnerable. Vulnerability varied with land use adjacent to the beach. These predictions about loss of nesting habitat have important implications for turtle populations in the region.     

Climate change adaptation in the Schleswig-Holstein sector of the Wadden Sea: an integrated state governmental strategy

Anthropogenic climate change constitutes a main challenge for the Wadden Sea. Accelerated sea level rise, increasing temperatures and changing wind climate may strongly alter present structures and functions of the ecosystem with negative consequences both for nature conservation and for coastal risk management. Being aware of these challenges, Schleswig-Holstein State Government decided to establish an integrated climate change adaptation strategy for the Schleswig-Holstein sector of the Wadden Sea. The strategy was adopted in June 2015. It aims at the long-term maintenance of present functions and structures as well as the integrity of the Wadden Sea ecosystem in a changing climate. The strategy was prepared by a project group consisting of representatives from State authorities as well as from nature conservation organisations and local institutions. First outcome of the strategy is that extra adaptation measures will not be necessary in the coming decades. However, pending on the future rate of sea level rise, shoreline erosion and sediment deficits in the Wadden Sea will increase and sooner or later drowning of tidal flats and terrestrial habitats like beaches, primary dunes and salt marshes will start. At the time when management measures to counteract the negative developments become expedient from a nature conservation viewpoint as well as for coastal risk management, adequate actions with minimized ecological interferences are possible. It is assumed that balancing the sediment deficits as the main adaptation measure may be implemented most efficiently by concentrating sediment suppletion at locations where natural forces organize redistribution in the Wadden Sea. Local technical coastal risk management measures like the strengthening of sea defences will, nevertheless, remain necessary as well.     

Climate change impacts on a large-scale erosion coast of Hai Hau district,Vietnam and the adaptation

Among the effects of global warming, sea level rise (SLR) and severe typhoons pose the greatest threat to the stability of human settlements along coastlines. Therefore, countermeasures must be developed to mitigate the influences of strong typhoons and persistent SLR for coastal protection. This study assesses climate change impacts on coastal erosion, especially in two projected SLR scenarios of RCP2.6 and RCP8.5. The results show that SLR and severe typhoons lead to the increase of coastal erosion, beach lowering and scour. Moreover, as in projected SLR scenarios, average waves in high tide can cause severe soil erosion at inner slopes and lead to dyke failure by 2060. The paper highlights the need for additional countermeasures to protect the coast of Hai Hau district against SLR and severe typhoons. Among the alternatives available for countering these threats, applying soil stabilization and soil improvement combined with geosynthetics are promising strategies for coastal structures. Hybrid structures can be used with earth reinforcement and soil improvement. Additionally, the paper emphasizes the importance of multiple protective adaptations, including geosynthetics and ecological engineering measures against climate change-induced severe erosion on the coast of Hai Hau district.     

Coastal erosion and shore protection: A brief historical analysis

Since the Neolithic, humans have gathered along coastal plains, where they had to face sea level rise and subsidence without the technology to oppose these processes. When sea level stabilized, approx. 6.000 yr. B.P., coastal colonization was allowed, but where mountain deforestation was carried out river sediment input increased tremendously: settlements were disconnected from the shore and harbour siltation occurred. Shore erosion was a limited process at the time and local solutions were adopted: clay dikes, wood piles, fascinates and rock revetments. Along the Mediterranean, in China and Japan the construction of more complex structures has been documented since the Middle Ages. Further human development, with river bed quarrying, wetland reclamation, dam construction and mountain re-afforestation, favoured a coastal erosion that nowadays threatens most world coasts. From the Venetian “Murazzi” to the recent 114-km-long concrete element defence at the Yellow river delta, shore protection structures evolved following the different needs (protect coastal communication routes, urban and industrial settlements, tourist resorts). Beach nourishment, previously performed with inland quarried materials, is now intensively carried out with marine aggregates. The vernacular solution, left to undeveloped countries, has been recently revaluated by “green engineering”. However, with Sea Level Rise, the debate of whether to defend, accommodate or retreat is open.     

Coastal inundation in the north-eastern mediterranean coastal zone due to storm surge events

Low-elevation coastal areas and their populations are at risk during and after the appearance of a storm surge event. Coastal flooding as a result of storm surge events is investigated in this paper for a number of areas around the north-eastern (NE) Mediterranean coastal zone (Adriatic, Aegean and north Levantine seas). The sea level rise (SLR) due to storm surge events is examined for the period 2000?C2004. Wind data, atmospheric pressure and wave data for this period as well as in situ sea elevation measurements (from stations around the Mediterranean coasts) were used. Potential inundation zones were then identified using a 90-m horizontal resolution digital elevation model (DEM). At these zones, the sea surface elevations were calculated for the study period, using the collected data and a 2D storm surge simulation model (1/10^o??1/10^o) output, examining the sea level alteration in specific coastal areas, where in situ measurements are absent and are characterised as ??risky?? in inundation areas, due to their topography. In order to determine the level of storm track implication on major SLR incidents, the trajectories of the respective storm events were computed. The aim of this paper is to investigate the major storm surge events that appeared during the study period, identify the major ??risky?? costal regions along the north-eastern Mediterranean coast and determine their hazard level due to inundation caused by storm surge phenomena. The combination of the risk level determination of an area and the calculation of sea level alteration is an important tool in terms of predicting and protecting the coastal area from extreme meteorological incidents.
