ABSTRACT
Climate change interacts in a particular perspective with the varieties of human activities and other drivers of coastal change. The phenomena of Sea Level Rise (SLR) are major impacts of global warming. Sea level rise may impact critical infrastructures such as jetty, coastal road, and the local community. This article aims to investigate the impact of inundation due to the Sea Level Rise along the Selangor coastal using the geospatial technique. The main objectives of this study are to predict the rise in sea level in the years 2020 and 2060, thus to determine the impact on infrastructure and land use along the Selangor shoreline. The data that were used were three altimeter satellites located at the border of Malaysia-Thailand, the Penang–Perak border, and the Straits of Johor as well as the three JUPEM tide gauge data. Hydrodynamic modelling along the coastline was developed using a MIKE 21 Flow Model. This hydraulic stimulation numerical is an ideal method for coastal studies. The parameter that has been used consists of bathymetry, currents speed, current direction and tidal data. The impact of sea level rise on the whole study area had shown that water was rising from 0.051 to 0.289 in the years 2020 and 2060. The impact of inundation shown that 192-274 units of infrastructures were potential to affect in period 40 years. The cropland and settlement area have been shown to be the most impacted land use area, which is caused by inundation ranging from 14.31% to 18.42% and 3.90% to 5.19% respectively. Therefore, the finding of this study can be used as a significant tool by coastal managers for developing sustainable resource management practices for future development.
