Time series geospatial assessment of potential erosion risk using Gavrilovic method and open-access geospatial data
Session
Civil Engineering, Infrastructure and Environment
Description
One of the worldwide environmental concern is the soil loss or soil erosion. The present study aims to investigate spatial-temporal distribution of intensity or density of erosion processes in last 18 years (2000– 2018). The most used model in our region known as Gavrilovic model has been implemented. The model was implemented in two time series, annually. The input data such as geology, topography (DEM), land cover, stream network catchment have been collected and recorded from different local and freely geoportals and organizations. The validation of results was made through the regular field checks and observations. In the year 2000, the most of study was observed in the “High” (31%) and “Very High” (27%) category of erosion risk, whereas in the year 2018 the most of study area was observed as “Moderate” (40%) and “High” (27%) erosion risk category. Furthermore the present study demonstrates the potential of GIS in conjunction with open- access geospatial data in order to investigate the environmental degradation.
