Event-based rainfall-runoff modelling of the Kelantan River Basin

Abstract

Kelantan River basin is one of the major basins in Malaysia. It is located at the North Eastern part of Peninsular Malaysia at latitudes 4 40' to 6 12' North and longitude 101 20' to102 20' East .The maximum length and breadth of the catchment are 150 km and 140 km respectively. The river is about 248 km long and drains an area of 13,100 km2, occupying more than 85% of the State of Kelantan. There are six sub-basins in Kelantan River basin namely Galas, Nenggiri, Pergau, Guillemard Bridge, Kuala Krai and Lebir. The entire basin contains large areas of tropical forested mountains, lowland forest and limestone hills. Currently, there are many activities involving land use changes from lowland forest to vegetation and urban area.
