| Summary: | River is important to humans and other organisms on earth as they are essential resources for living. Erosion, transport and deposition are among the number of processes that influence the sedimentary content and quality of river water.This research discusses the sediment transport of Sarawak Kanan River. It describes a total of 16 sediment data obtained from October 2014 until December 2014 at Sarawak Kanan River Catchment in the river sediment collection and analysis project. The objective of the study are to determine the sediment yields throughout the period, the factors and correlation that influencing the sediment mobility and to identify and evaluate sediment equations that best predict sediment transport rate for Sarawak Kanan River. Data collection including suspended load, bed load, bed material and flow discharge have been carried out at the selected site. The correlation value,R2 of flow discharge with suspended sediment concentration, water level, bed load, suspended sediment load are varies between 0.6387 to 0.9642 which indicates that they are each most directly proportional with each other. The sediment transport equation assessments have been carried out using Einstein,Einsten-Brown, Meyer-Peter-Muller,Shields,Yang, Engelund & Hansen, Ackers & White and Graf equations. In this study, Engelund & Hansen equation gives the highest value of accuracy which is 87.5% and followed by Yang and Graf equation with accuracy of 12.5% from the total data. Therefore, it is necessary to establish effective sediment and river management strategies that are economically, environmentally, and socially sustainable without compromising the needs of future generations. |
