【 摘 要 】

Nowadays, the mining of sand resources from rivers areas especially in Perak state is a common practice and may lead to destruction of public assets as well as impacts or increase stress on commercial and noncommercial living resources that utilize these areas. This study was carried out to determine possible river sand removal capacity and their consequences towards Sungai Perak. Acoustic Doppler Current Profiler (ADCP) is utilized to make river profiler in term of velocity meshes and river bed depth. It also could measure the total discharge of a particular cross-section. In this study, 8 locations of the river were chosen to analyze the river discharge profile either symmetrical or non-symmetrical. From the result and analysis, only one out of eight location showed symmetrical profile. This result showed that the flow of water in the river was not in a good condition and river sand mining in a controlled condition need to be conducted to improve the quality of the river. Other than that, the average flow of Sg. Perak at Pendiat (7770 km2) is 220 m3/s which is same magnitude that was reported by Department of Irrigation and Drainage. Based on this result, it is possible to mine sand island and this activity will reduce local scouring.
