【 摘 要 】

This study evaluates the climate change impact to the depth of inundation due to dam breaks during a heavy rainfall through Hydrological Engineering Centre-River Analysis System (HEC-RAS). Increasing of intensity rainfall is an evidence of climate change exists and it explicitly informs that possibility of higher inflow rates will be also getting bigger. This fact become main concern in connection with raising probability of dam breaks with higher magnitude of flooding. This current study determines the flood inundation depth due to Chereh Dam failure by including the Climate Change Factor (CCF). The result of analysis point out that the depth and level of flood due dam break creates a significant impact and risk to the Kuantan City such as inundated of transportation networks and also various public facilities.
