Coastal vulnerability assessment for Peninsular Malaysia coastline

摘要

The main objective of the present study is to develop a coastal vulnerability index (CVI) for the Peninsular Malaysia coastline. This study incorporated six variables to assess the CVI for the study area. These six variables consist of geomorphology, shoreline change rate, maximum current speed, maximum tidal range, significant wave height and sea level rise. The ranking is on a linear scale from 1 to 5 in order of increasing vulnerability; value 1 represents the lowest risk ranking assigned to the coastline whereas value 5 ranks the coastline with the highest risk. A total of 1,633 km of coastline was evaluated and of this, 3.3% of the mapped shoreline is classified as being extreme vulnerability, 11% of Peninsular Malaysia shoreline is classified as very high vulnerability and 40 % as high vulnerability.
