GIS BASED SOIL EROSION MODELLING

The loss of top soil in the World has brought about low harvest yield, diminishment of store limit, cost increment of water treatment, and hindering consequences for oceanic life and natural life territories. The loss of soil from farmland may be reflected in reduced crop production potential, lower surface water quality and damaged drainage networks. An increasing awareness by scientists, governments and the general public realized that soil erosion is an important problem in the whole world. In connection to water, models are a method for foreseeing the conduct of water proceeding onward scenes for various issues confronting society in the past and today. The reason for this survey is to quickly examine a few models on soil erosion on scenes to give data about them to help and serve in an appropriate way keeping in mind the end goal to talk about specific issues identified with hydrology and soil erosion forms. The outcomes from soil erosion models reenactment of procedures have been the essential information for land use planning in the catchment, particularly to better seeing how the hydrological cycle, soils and vegetation interface between themselves. In this paper we have discussed three models RUSLE, WEPP and AGNP. We can use the latest technology models for accurate measurement of soil erosion and deposition.
