Abstract: Kulim River catchment is located in the southern part of the state of Kedah in the northwestern corner of Peninsular Malaysia. Kulim River slopes are steep and the channel elevation drops from 100m down to 18m average mean sea level at the central area of the Kulim River catchment. Currently, the catchment area is undergoing rapid urban development with oil palm and rubber plantation being replaced by rapid urbanization and this will result in discharge and bed erosion increment or scouring and deposition. Frequently floods that occur in Kulim River Catchment has caused extensive damage and inconvenience to the community especially floods event in October 2003 which exceeds 100 year ARI. Hence, previous studies for Kulim River (DID 1996, Yahaya 1999, Lee 2001, Ibrahim 2002, Koey 2003) were conducted to determine the river behavior and the effectiveness of the flood mitigation projects due to the rapid urbanization development. However, previous results of sediment data and river cross section based on the observed data are up to the year 1999. Thus, this paper describes the analyses and evaluation on sediment transport for Kulim River catchment by using newly observed data in 2004.
