Modeling coastal vulnerability index to sea level rise for the east coast of Penisular Malaysia

Abstract

Sea level rise is a global phenomenon that all littoral states, including Malaysia, need to plan for. Thus far sea level rise scenarios have been using global data and scenarios that only depict inundation areas without taking into account socio economic and quality of life. Malaysia is vulnerable to sea level rise particularly areas located on the East Coast of Peninsular Malaysia facing the South China Sea where the waves are larger, especially during the monsoon season. It is also our study site covering over 675 km and fifteen districts located along the coast. Models of sea level rise were performed using three sea level rise scenarios: an increase of every 1, 2 and 3 m in areas that have been selected, including major town, industrial areas and estuaries.
