Analytic Hierarchy Process (AHP) Based Soil Erosion Susceptibility Mapping in Northwestern Himalayas: A Case Study of Central Kashmir Province
نویسندگان
چکیده
The Kashmir Valley is immensely susceptible to soil erosion due its diverse topography and unstable geological formations in the Himalayan region. present study helps assessing spatial distribution prioritizing zones Central region covering Sindh Dachigam catchments. implemented GIS-based analytic hierarchy process (AHP) weighted sum method (WSM) using datasets of precipitation, map, satellite imagery derived eleven factors (topographical derivatives, LULC, soil, drainage, rainfall, lithology, wetness index greenness an area). ratings weightage were proven be unbiased reliable based on observed value consistency ratio (CR) (i.e., 0.07). depicts 41% total area extremely vulnerable erosion. slope varies from 0–62° with mean 22.12°, indicating 467.99 km2 (26%) 281.12 (15%) under high very zones, respectively. NDVI NDWI maps indicate severity 40% 38%, respectively, highly zones. High drainage density curvature 18.33% 22.64% area, will assist planning implementation conservation measures.
