COVER FEATURE SEA LEVEL RISE IN MALAYSIA By Nor Aslinda Awang, Mohd Radzi Abdul Hamid, E. M. Yahaya, N. & Shaaban, A. J., National Hydraulic Research Institute of Malaysia (NAHRIM) S ea level rise (SLR) is attributed to ocean thermal expansion, melting Greenland and Antarctic glaciers and decrease in terrestrial storage (Dasgupta et al, 2007). SLR can have a high economic impact especially on low lying areas, such as the destruction of assets and disruption to economic sectors, loss of human lives, mental health effects, or loss of plants, animals, and ecosystems. The severity depends on their extremes, exposure and vulnerability (IPCC, 2012; McLean, 2009). SLR may reduce the size of an island or a state and its’ infrastructure such as, airports, roads, and capital cities, which tend to be situated in coastal areas. Inundation, erosion, and other coastal hazards; threaten vital infrastructure, settlements, and facilities; and thus compromise the socio-economic well-being of island communities and states (Handmer et al., 2012). SLR varies spatially hence coastal nations need to ascertain the likely extent of local impact. The Malaysian Study on the Impact of Climate Change on Sea Level Rise (NAHRIM, 2010) was conducted with the purpose of first assessing the rates of SLR by analyzing the observed tide gauge and satellite altimeter data around the Malaysian coast, then determining the projection of the sea level rise along the coast. Due to financial constraints, the SLR Study was conducted in several phases:- 15
