dc.description.abstract To date, Kerteh is under rapid development via expansion of the industrialization area as well as the increase in population. Thus, the study of sediment yield was conducted in Kerteh River catchment area. The methodology of this study is divided into two parts which is the ground sampling and using GIS technology (A VSWA n to create a watershed model to predict the sediment yield in the study area. For the ground sampling, the water samples from the station 1 and station 2 were collected to determine the suspended sediment concentration (SSC) from the study area by using SSC method. Furthermore, the actual land use activity of the study area was recorded which the latter was used in the A VSWA T. The digital elevation model, land cover data, stream network data, soil data, weather data, and precipitation data were loaded into AVSWAT to simulate the suspended sediment yield in the study area. The simulation of the sediment yield must be compare with the SSC to make the A VS WAT to simulate an accurate data of sediment yield in the study area. The correlation coefficient is use in this study to determine the relationship between SSC and the simulation of suspended sediment load by the A VS WAT in the station 1 and station 2. The correlation coefficient has shows a very strong relation between the SSC and simulation data by the A VSWA T. This is due to the R value of the station 1 is 0.926 and station 2 is 0.864. The prediction of the sediment yield in the Kerteh River catchment area from year 2015 until year 2040 is in the ranges 731700 metric tonne until 1782000 metric tonne. Thus, it can concluded that, the study of the sediment yield in a catchment area can be using GIS technology (A VSW AT) to create a watershed model to predict the sediment yield. Since, it is easier and economic if compare to do the ground sampling. en_US
