Abstract: Bertam river (Sg. Bertam) is one of the main rivers in Cameron Highlands, Pahang. The downstream river has changed as a result of water storage and regulation in the Ringlet reservoir. The changes include a reduction in discharge volume and water level downstream the reservoir. This study deals with the impacts of Ringlet reservoir to downstream hydraulic capacity of Bertam river. In order to study the impact, the hydraulic simulation of river was carried out using the 1-D hydrodynamic software of XP-SWMM. The software is capable to model the difference of water level before and after the reservoir as well as to estimate the fluctuation of water level along the river. Eighteen river cross stations were surveyed on August 2008 along the Sg. Bertam. The distance between each cross section was approximately I km. This study was found that the reservoir had given significant impacts to the downstream hydraulic capacity in Bertam river. This includes decreasing in river discharge, reduction in bankfull width and the characteristics of the downstream flood scenario.
