摘要

Monsoon and flash flood have been dominating the entire urban areas in Peninsular Malaysia, such as in Penang, upper Kinta Valley, Malacca Basin, East Coast of Kelantan, Terengganu, Pahang and Johor. From the larger scale view, global warming causes uncertainties of receiving rainfall amount in Malaysia. Improper urban development planning and increased number of impervious area causes hazardous impact towards urbanized land use properties within basin. Complexities of constructed buildings, road networks and urban landscape makes difficulties for flood mitigation and rehabilitation planning towards reducing flood disaster. Thus require of a new dimension representing urban flood modelling realistically. Concepts of urban runoff process need to be reviewed in order to sustain the existing environmental condition.
