Kuantan is one of the flood prone areas that identified in Pahang. The main river basin is Kuantan River. This basin is responsible to drain water from the correspond catchment area to the South China Sea . Due to heavy local rainfall is often occur in the Kuantan area , Kuantan River as main river basin is cannot longer support the volume of the rainfall will causing the flood to the areas surrounding. It is getting worse year by year with heavy rainfall especially at low level area cause of clog drain, design failing, wrong estimation and other natural causes.
