Prioritization index of soil erosion intensity for management practices within Mountainous River using Geomatics

Abstract

Mountainous rivers are always prone to severe soil erosion. Streams runoff from steep slope carriying heavy sediment yield to the plain. In the present study an attempt has been made to prioritize the microwatershed (MWS) for management practices within a subwatershed (SWS) Priority index was made based upon the intensity of soil erosion zone in MWS. This study identified and statistically ranked the MWS in order to do further analyses for protection measures. The main elements of soil erosion intensity assessment in this study are land cover, slope and forest density.
