| dc.description | Land use activities within basin area are one of the factors contributing to deterioration of river water quality affected to erosion from disturbed soil. Sediment yield in the form of suspended solid in the river water body affected from soil erosion is transported to the ocean and will give negative impacts especially in the coastal area. The aim of the study was to determine potential soil loss using the Revised Universal Soil Loss Equation (RUSLE) model and the sediment yield (SY) in the sub catchments of Pahang River using Geographical Information Systems (GIS). The potential soil loss model (A) was determined using integration of RUSLE model, satellite data and GIS by utilizing information on rainfall erosivity factor (R) resulting from interpolation of rainfall data, soil erodibility factor (K) by field measurements and soil map, vegetation caver factor (C) using satellite images, topography factor (LS) using Digital Elevation Model (DEM) and conservation practice factor (P) using satellite images. The sediment yield (SY) was analysed by the multiplication of the potential soil loss (A) and sediment delivery ratio (SDR). The analysis results showed that the rate of potential soil loss in the sub catchments of Pahang River ranged from very low (0.01 tonnes/ha/yr) to extremely high (95.47 tonnes/ha/yr). The area covered by very low to low potential soil loss was about 99%, while the moderate to extremely high potential soil loss was covered only 1%. The validated results showed the maximum erosion potential recorded was 36.35 tonnes/ha/yr, while most of the sampling area ranged from 0 tonnes/ha/yr to 19.06 tonnes/ha/yr. The dominant factors contributed the occurrence of high potential soil loss in the study area were LS and K factors and distributed at the western towards the eastern of sub catchments area. While, the sediment yield obtained only 1% from the potential soil loss in the sub catchments. The sediment yield value in Pahang River become higher when approaching to the river mouth because of the topographic character, climate, vegetation type and density and land use across the sub catchments. Over all, the potential soil erosion gave small impact to the sediment yield in the water body. The integration of GIS and RUSLE gave results of analysis more significant in determination of potential soil loss and sedimentation particularly in wide area with various types of land use, topography and density of the plant cover.,Master/Sarjana | |
