Title: Coastal Floods in View of Projection Sea Level Rise in Klang, Malaysia: Assessing Damage Costs and Adaptation Measures

Coastal zones are the location of many villages, town and cities. In the state of Selangor, in which Klang and Kuala Langat districts are located, about 21 percent of its population are in the coastal zone. Selangor has also one of the highest population growth rates in Malaysia and this rate is expected to continue. Global climate change is predicted to cause an increase in sea level rise, impacting the coastal zone. Other related impacts are increase in the frequency and intensity of storms and storm surges, shoreline erosion, inundation of land, flood damage and saltwater intrusion into freshwater land aquifers. Preliminary assessment of these hazards is important for vulnerability of coastal areas to ensure the sustainability of our coastlines. In this study, it will assess coastal floods due to the impact of the sea level rise. In year 2100, at study area is it projected that a total of 19,676.11 hectares of land will be affected by the sea level rise. More housing and industrial property will be affected if the coastal floods spread further inland. Putting figure to loss from impact of sea level rise is a complicated task. There are direct and indirect loss, tangible and intangible loss to be considered. Flood has been a devastating natural disaster in Malaysia and its increase in frequency and magnitude had caused substantial financial losses apart from the intangible losses. Coastal flooding due to sea level rise will become more rapid in the coming years. The output of this study will prepare coastal and estuary future land use zoning guidance and other mitigating measures to reduce impact of climate change on sea level rise on a Mukim Kapar, Mukim Klang and Mukim Jugra. This assessment will benefit various implementation government agencies, Non-Government Organisations (NGO) and local stakeholders, especially as a tool in adaptation planning and development at Malaysian coastal areas in the forthcoming future.
