Abstract

Sarawak River had experienced several terrible flood events over the past 50 years, with the worst being in 1963, followed by February 2003, January 2004 and January 2009 flood. After the incident, a flood bypass channel proposed as a flood mitigation measure to reduce the flooding condition along the Sarawak River. The proposed flood bypass channel is 8 km long with 250 m base width man-made channel starting from Kampong Paroh to divert flood waters from Sarawak River away from Kuching city to Batang Salak. The main purpose of this project was to review the flooding problems in flood-prone areas of Sarawak River basin and analysis the operation flood diversion barrage in conjunction with the downstream barrage during the king tidal event. Sarawak River and its floodplains were modeled using one-dimensional hydrodynamic modeling approach, by develop the Wallingford Software model - InfoWorks River Simulation (RS), with the GIS applications, to obtain the flood hydrographs of the river and its floodplains in extreme flooding condition of flood event of 2009. The simulated results of January 2009 flood obtained showed that the operation of flood diversion barrage and downstream barrage had been diverting significant portion of flood waters from Sarawak River. Results taken from Kuala Maong showed a total average water level reduction of 6.5%. It is showed that the operation of flood diversion change in conjunction with downstream barrage be able to reduce the flood condition of Sarawak river.
