ABSTRACT: Kota Tinggi located in the southern state of Malaysia, i.e. Johor Baru, experienced severe floods in December 2006 and January 2007, which was due to prolonged and intense rainfall. Johor River was inadequate to accommodate the water and at the same time the flow unable to escape the swolen river, hence water inundated the town. One of the river characteristics that may contribute in flooding is the meandering shape. Therefore it was proposed to do a hydraulic model that simulated some alternate channels that straightened some parts of the river. The model used one dimensional steady state approach using HEC-RAS software. The simulation result of the existing condition estimated that January 2007 flood event had a return period of 100 years. From the hydraulic model, it can be concluded that the choice of location and the length of the alternate channel had an effect on how much water level reduced.
