For  effective erosion control, it is needed to estimate the soil loss and to identify the key factors  using an effective and accurate method.  Thematic maps of R-factor, K-factor, L-factor, S-factor, C-factor, P- factor and population  density for two different years were prepared from the information of rainfall data, soil  analysis, contour map, landuse maps and population data respectively. Soil erosion maps,  1981 and 1993 for Kandy district, Sri Lanka were prepared with combining the all derived  information of USLE using GIS facilities. The maps showing the changes between two time  periods for erosion, rainfall, landuse and population density were developed to identify the  effects of selected parameters on soil erosion in the study area.  The results show the increment of the level of soil erosion with the time, mainly due to the  variation of rainfall and it can be reduced changing the pattern of land uses, while the other  factors such as soil and slope remain same. It can be seen a relationship between the changes  of population density and that of land uses, which are more related to erosion and a  methodology should develop to correlate these in detail.  0aGeographic information systems 0aSoil conservationzSri LankazKandy0 aApisit Eiumnoh,eChairperson1 aShivakoti, Ganesh P.,eExamination Committee0 aKaew Nualchawee,eExamination Committee2 aThe Norwegian Government (Norway),eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
