Development of Topographic Factor Modeling for Application in Soil Erosion Models

摘要: The fast changes in soil use and higher vegetal resource demands favor the triggering of water erosion that needs to have its rates expressed space time for proper adaptation control practices resources agricultural planning. physical processes disaggre‐ gation, transport deposition define erosive process are hydrologically directed movement on undergoes interference topography, climate, class land use, so studies regarding theme based intense experimentation effects variations these factors sediment production. estimate topographic variables, although benefitted by automatic generation spatial distribution made possible Geographical Information Systems (GIS’s), is target controversy related formulation algorithms this end, threedimensional calculation not a current procedure geoprocessing programs [1].
