Identification of Soil Erosion Susceptible Areas in Hinglo River Basin, Eastern India Based on Geo-Statistics
Journal Title: Universal Journal of Environmental Research and Technology - Year 2015, Vol 5, Issue 3
Abstract
Reliable databases are the prime requirement for identifying vulnerable erosion zone in order to execute alleviation measures. Geo-morphometric characterizations of a watershed are commonly used and scientific approach in this connection. In the present paper un-gauged 5th order Hinglo River Basin draining through the Rarh regions of Eastern India as a tributary of the river Ajay having 444.308 sq. km. area have been selected for detection of erosion susceptible areas. A total of 15 (7 relief and 8 drainage) geomorphometric parameters have been considered for the study with the aid of Remote Sensing (RS) and Geographical Information System (GIS). Principle Component Analysis (PCA) based Average Weighted Composite Score (AWCS) method is used to assimilate the erosion driving variables and thereby to fabricate spatial soil erosion vulnerable map. According to the result, high to severe erosion susceptibility zone counts about 34.85% (154.84 sq.km.) of the basin area, mainly concentrated in the upper catchment due to excessive drainage conditions, steep slope, high dissection and ruggedness index, surplus drainage density and stream frequency. These erosion hotspot areas of the river basin needs special attention to take up mechanical soil conservation measures, gully control structures and grass erection to protect nutrient rich topsoil loss this agriculturally conquered region.
