Abstract

Soil erosion is one of the serious issues threatening the environment. It is a growing problem especially in areas of agricultural activity where soil erosion not only leads to decreased agricultural productivity but also reduces water availability. This leads to drastic degradation of the agricultural lands. . Uncontrolled land use, deforestation, over cultivation, overgrazing and exploitation of biomass for firewood, construction and other household uses due to increasing population ultimately lead to severe soil erosion. So there is a need to take up conservation and management measures which can be applied to check further soil erosion. Revised Universal Soil Loss Equation (RUSLE) is the most popular empirically based model used globally for erosion prediction and control. In the present study, RUSLE model has been adopted to estimate the soil erosion in the Palayakottai watershed of Tamil Nadu, India. This model involves calculation of parameters including runoff-rainfall erosivity factor (R), soil erodability Factor (K), topographic factor (LS), cropping management factor (C), and support practice factor (P). Layer wise thematic maps of each of these factors were generated using GIS platform using various data sources and data preparation methods. The results of the study indicate that the annual average soil loss within the watershed is about t/ha/yr (metric ton per hectare per year).
