The Universal Soil Loss Equation (ISLE --Wischmeier and Smith, 1978) was applied to estimate the annual soil loss from the watershed in 1976 and 2002. The analysis process on land use land cover change is based on geo-processing of GIS utilizing the raster and vector analysis. The analysis result of' land use land cover change between 1976 and 2002 show that the agriculture land was expand and the forest area was decrease in the study area. A raster based Geographic Information System (GIS) was used to interactively calculated soil loss and erosion hazard map. The result shows that increase soil erosion in the agriculture land and suggests that mitigation measure should be taken for prevention of further degradation. High resolution satellite images are very effective tool for not only monitoring the land use land cover change but also estimating soil erosion in the watershed. Similarly, GIS is also an effective tool in analyzing by overlaying various vector maps related to factors affecting in land use land cover change and soil erosion 0aLand usexRemote sensingzCambodiazTonle Sap 0aSoil erosionxRemote sensingzCambodiazTonle Sap1 aSamaraKoon, Lal eChairperson1 aChen, Xiaoyong eExamination Committee1 aSusaki, Junichi eExamination Committee1 aShrestha, Rajendra Prasad eExamination Committee 2 aGovernment of Japan eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
