This event will then lead to sedimentation problems in the river systems. Not only that, rapid development due to urbanization activities such as deforestation, sand mining and housing construction also contributed on making the soil erosion problems getting worse. This study uses computer simulation to simulate the flow pattern and changes in bed elevation. The objectives of this study are to simulate the effects of groynes on a straight channel flow behaviour and to predict the morphological bed changes due to its different alignment of groynes. The study on hydraulics and morphodynamics in a straight channel had been undertaken by using computational model of Nays2DH which was developed by International River Interface Cooperative (iRIC). Nays2DH is a two-dimensional, depth averaged, horizontal, unsteady coupled flow and sediment transport hydrodynamic model that can analyse flow, sediment and morphological change in the bed and banks of a river. The simulations were carried out for three cases which are straight river without obstacle, straight river with obstacles perpendicular to the river banks and straight river with obstacles parallel to the river banks. The findings prevailed that changes in bed elevation and velocity along the river channel and also across its sections. Comparison were made for all three cases to determine the most efficient obstacle arrangement to control sediment and flow. It is found that placing obstacles perpendicular to the river banks are the most efficient method. zulraizam UTM 66 p.
