Geoinformatics Based Natural Disaster Management- A Case Study from Yercaud Hills, Tamilnadu, India

Soil erosion is the serious environmental problems in hilly terrains. An attempt has been made to delineate the soil erosion prone areas in Yercaud hills using Geoinformatics tools (Remote sensing and GIS). The study area, Yercaud is the hill station in the Servarayan range of hills in Eastern Ghats of Taminadu. The parameters considered for identifying the soil erosion prone zone are Soil, Geology, landuse/land cover, drainage, rainfall and Geomorphology. There are 4 drainage patterns observed, the hill region is majorly covered by Charnockite rock type. Comparing all these parameters the soil prone areas have been observed in the south eastern part of the region.
