Coastal Damage

The coastal areas of both Jayapura Municipality and Regency which is directly opposite to the Pacific Ocean with the multifunctional use is a vulnerable area to disasters. The coastal vulnerability is determined by considering some influential factors, that is geomorphology and elevation to minimize the coastal damage impacts. The purpose of this study is to determine the coastal vulnerability index of Jayapura City and Regency focusing on the coastal geomorphology and elevation. The study area covers a coastal area of 241.86 km along the coastlines of Jayapura Municipality and Regency. The study method includes data collection on the coastal geomorphology and elevation characteristics. The value of coastal vulnerability index of each parameter is determined by dividing into five categories of coastal vulnerability. The result shows territorial division as follows: 145.88 km (61.18%) was not vulnerable, 33.14 km (13.90%) was less vulnerable, 29.03 km (12.17%) was a moderate vulnerability, 12.12 km (5.08%) was vulnerable, and the remaining 18.29 km (7.67%) was very vulnerable. The coastal vulnerability of Jayapura City coastal areas categorized into three classes, i.e. not vulnerable, moderate vulnerable and vulnerable, while the Jayapura Regency coastal areas felt into the following classes: not vulnerable and moderate vulnerable. The most vulnerable areas were of Abepura District, South Jayapura District and Muaratami District, all in the Jayapura Municipality administration. Those areas with high elevation level were not vulnerable at all.

Many coastal areas and infrastructure suffered from unprecedented hazards such as storms, flooding, and erosion. Thus, it is increasing the vulnerability of urban coastal areas aggravated with the absence of coastal green infrastructure. Given the state of coastal environments, there is a genuine need to appraise the vulnerability of coastal cities on the basis of the latest projected climate scenarios and existing condition. Hence, to asses, the vulnerability level of Mataram coastal, the Coastal Vulnerability Index (CVI) accompanied by pre-assessment of readiness to climate disruption. The CVI used to map coastal into five classes of using GIS. As a case study, this approach applied to Mataram City: one of the tourism destinations in Lombok. Two of sub-districts in Mataram City, Ampenan and Sekarbela, laying in the shorelines have undergone coastal flooding and erosion. One of them, Ampenan sub-district, experienced flooding due to river-discharge and became the most severe location during inundation. Results indicated that along ±9000 meters of Mataram coast possess vulnerability level in moderate to very high-risk level. The assessment also showed that sea-level rise is not the only critical issue but also geomorphology and shoreline changes, the existence of green infrastructure, also human activity parameters took important part to be assessed.

Kerentanan pantai adalah kondisi yang menggambarkan keadaan mudah terkena dari suatu sistem alami serta keadaan sosial pantai. Kerentanan pantai yang diakibatkan erosi merupakan ancaman yang dapat menimbulkan kerugian yang besar bila tidak ditangani dengan tepat. Perlu dilakukan sebuah upaya mitigasi bencana erosi pantai berupa tahap awal dengan penilaian indeks kerentanan pantai. Upaya mitigasi bencana dapat dimulai dengan membuat pemetaan indeks kerentanan pantai yang berdasarkan penilaian lima variabel, yaitu:  geomorfologi pantai, tipologi pantai, kemiringan pantai, vegetasi mangrove, dan penggunaan lahan pesisir. Metode yang digunakan dalam penelitian ini adalah metode spasial yang digunakan untuk menyusun peta tingkat kerentanan pantai yang diawali dengan input data ataupun peta berdasarkan pada variable yang ditentukan, dilanjutkan dengan metode kuantitatif yang digunakan untuk menganalisa data yang tersaji dalam bentuk angka dengan menggunakan sistem skoring, dilanjutkan dengan metode deskriptif yang digunakan dalam mendeskripsikan sejumlah variabel yang berkenaan dengan penelitian. Penelitian ini dilakukan pada bula Mei-Agustus 2017, lokasi penelitian berada di kawasan pesisir pantai Kabupaten Rembang pada 6 Kecamatan Pesisir dan 40 desa. Hasil dari penelitian ini berdasarkan penilaian Indeks Kerentanan Pantai di Kabupaten Rembang didapatkan tingkat kerentanan sangat tinggi (400-450) berada di Kecamatan Kaliori, kerentanan tinggi (360-400) berada di Kecamatan Sarang, Kragan, dan Lasem, kerentanan sedang (290-360) berada di Kecamatan Sluke, dan kerentanan rendah (240-290) berada di Kecamatan Rembang. Dari lima variabel, yang sangat berpengaruh terhadap kerentanan bencana erosi pantai adalah tipologi pantai. Coastal vulnerability is a condition which describes the State of a system of easily affected by natural and social circumstances of the beach.Coastal vulnerability arising from erosion is a threat that can cause great harm if not handled appropriately.Need a coastal erosion hazard mitigation efforts in the form of an early stage with an assessment of the vulnerability index beach.Disaster mitigation efforts can be initiated by creating a mapping coastal vulnerability index based on the assessment of the five variables, namely: coastal geomorphology, typology, the slope of the Beach Coast, mangrove vegetation, and land use. The methods used in this research are spatial methods used to draw up a map of the level of vulnerability of beach, begins with the input data or map based on variable is specified, followed by a quantitative method used to analyze the data that is presented in the form of numbers by using the scoring system, followed by a descriptive method used in describing a number of variables related to the research.This research was conducted in  May-August 2017, the location of the research lies in the coast of Rembang in 6 sub-districts and 40 villager.

Tourism development in Greece has led to increasing pressure on coastal areas, which makes the study of sensitive coastal areas essential, in order to find appropriate solutions for their shielding. The aim of this study is an estimation of the effects of an anticipated sea level rise for the touristically developed part of Pieria Prefecture, which includes the settlements Paralia, Skala of Katerini, Olympic Beach, Korinos Beach and extends north to the area of the Kitrous saltworks and south to the mouth of Mavroneri river. Therefore the Coastal Vulnerability Index (CVI) is applied, in an attempt to determine the susceptible parts to the potential sea level rise. CVI depends on the following parameters: (a) coastal geomorphology, (b) coastal slope, (c) shoreline erosion/accretion rate, (d) relative sea-level rise fluctuations, (e) mean tidal range and (f) mean significant wave height. The classification of the coast, which is of particular socio-economic significance since it hosts urbanized areas, into five CVI classes (from very low vulnerability to very high vulnerability), showed that 43.6% of the entire coastline is of very high vulnerability.

Climate change has brought about many threats to the ecosystem by inducing natural hazards, particularly sea level rise. Coastal areas then are subjected to many adverse effects of sea level rise, hence posing a risk to the safety of the coastal population, resources and assets. As part of the mitigation and adaptation measures against these effects, the Coastal Vulnerability Index (CVI) was implemented by many coastal regions. The CVI is an index-based tool to map the risks related to coastal changes. In Malaysia, the practice of CVI is still in its initial stages. Whereby, the Department of Irrigation and Drainage (DID) Malaysia had earlier carried out two pilot projects on CVI. The first is located at Tanjung Piai and the second at the west coast of Pulau Langkawi. This paper reviews the definition and concept of CVI. An alternative implementation approach of CVI in Malaysia is also discussed.

Mapping Vulnerability

Binh Thuan coastal zone, nearly 192,9 km shoreline, is well known for residential, recreational areas and minor industries. Shoreline is vulnerable to accelerated sea level rise (SLR) due to its low topography and its high ecological. The present study has been carried out with a view to assess the coastal vulnerability of SLR. Coastal vulnerability map has been built to the calculating results of the place vulnerability index (PVI). The PVI is derived by summing the CVI (coastal vulnerability index) and CSoVl (coastal social vulnerability index) scores. CVI is calculated from nine variables: Geology, geomorphology, coastal slope(%), shoreline change rate (m/yr), mean elevation (m), shoreline direction, mean tidal range (m), wave height (m) and SLR (mm/yr). We use two socioeconomic variables for CSoVI which are socioeconomic variable and relative distance to coast. Results of the vulnerable areas analysis indicate that 120,73 km2 is at very high vulnerable, 84,96 km2 high, 109,23 km2 moderate, 113,99 km2 low and 232,20 km2 very low. The method in this study which combine CVI, CSoVI and PVI together is new protocol of coastal vulnerability assessment for Vietnam coastal zone due to future SLR.
