GEOSPATIAL ASSESSMENT OF SOIL EROSION ON TIME SERIES USING EROSION POTENTIAL MODEL AND GEOSPATIAL TECHNOLOGIES

The present study aims to estimate average erosion and investigate spatial distribution of soil loss as well as the calculation of the amount of removed soil in the period between 2000 and 2018. In order to be achieved soil erosion potential and sediment yield in Mitrovica region (Kosova), Erosion Potential Model (EPM) also known as Gavrilovic method has been implemented, as the most used model in our region. The EPM is a quantitative method of estimation soil loss. An approach of Geographic Information System (GIS) and Remote Sensing (RS) have been presented and demonstrated in the present study. The model was implemented in two time series, annually. The input data such as climate parameters (precipitation and temperature) as well as other parameters (geology, topography, land cover) have been collected and recorded from different local and freely available datasets. Unaviable or unreliable data necessary for the model are calculated within the software procedure. Because of the lack of input data according the requirements of the model, the necessary data have been computed. The combination of GIS and RS have enabled to develop the reliable model. The performed results on this study will be m3/km2/year. The spatial-temporal distribution of erosion intensity maps and soil loss map in two time series were generated as thematic maps of 20m spatial resolution.
