Abstract

Mathematical models have been developed to resolve many problems that are related to water profile evaluation. The flow through weir can be solved using numerical methods and computer techniques. Storage in channel and river could be utilized by installing weir at strategic locations along the river. This approach might be benefited in flood control to the downstream area, but it could also cause flooding in the upstream due to the backwater effect. The problem is whether by the installation of those weirs will produce backwater at the upstream area. By using numerical equation the effective application of hydraulic structures such as weir can be determined. The computer program such as FEWMS Fst2dh is numerical program has ability to simulate the flow in structure hydraulics. The effectiveness of weirs at the upstream Sungai Plentong can be determined by using FESWMS Fst2dh modelling that is enable Surface Water Modelling System (SMS) software. The simulated water surface elevation will be used to identify which areas that are have problem with backwater. The result observed data shows that the existing weir in the channel at the upstream of Sungai Plentong can reduce to 80% of the channel water depth. The simulated of water level results shows that the weir did not producing significant increase effect of water level due a backwater.
