In the context of the various problems attributed by climate changes, river basin management is vital in ‘achieving the protection, improvement and sustainable use of the water environment’. This article discusses how hydraulic simulation could be used as a supporting tool in planning and developing a framework for river management such as Integrated Flood Management for a river basin. It also demonstrates how a hydraulic model for the Sarawak River Basin was run using InfoWorks River Simulation software. The model was used as a tool to provide necessary decision parameters in developing the logical framework which could act as a guide for planning involving various stakeholders’ participation. The figure on the upper section of the cover (Figure 7, pp. 56) shows the simulation of the January 2004 flood event with the flood bypass channel in the lower Sarawak River. The lower image on the cover (Figure 2, pp. 49) is a technical drawing of the flood bypass structure superimposed on a satellite image. The flood bypass would include an 8 km long, 250 m base width, 10 m depth earth-dug (nature-like) rectangular channel (Jurutera Jasa Consulting Engineers) which is expected to be completed by 2015.
