Integrated Method of Smartline Approach And CVI (Coastal Vulnerability Index) In Assessing Pangandaran West Coast Vulnerability

Abstract

Pangandaran West Coast is the famous tourism site besides many tourisms offer in Pangandaran Regency. These white sand beaches provide beautiful sightseeing, water sports, tourism facilities, culinary and many other interesting things. In contrary, there were many erosion evidences found and building damage during the field research, in this area that may harm the nature its self and the population as well. The aim of this research is to map the coastal vulnerability in Pangandaran West Coast by integrating Smartline Mapping approach and CVI (Coastal Vulnerability Index). Thus, we map vulnerability parameters in two directions, along and cross the coastline, that consist of 10 parameters such as beach material, wave exposure, hinterland relief, berm feature, grain size, berm height, beach face feature, significant wave height, coastline changes, and residential area density. Finally, after the mapped parameters were scored and calculated using CVI formula, the result showed that vulnerability index in Pangandaran West Cost ranged from 16.43 to 129.9 which divided into 5 vulnerability classes; 1) Very low, 2) Low, 3) Moderate, 4) High, and 5) Very High.
