Identification of potential zones on the estimation of direct runoff and soil erosion for an ungauged watershed based on remote sensing and GIS techniques

An investigation of soil and water resources is essential to determine the future scenario management attain food security. The improper watersheds results in a huge amount sediment loss surface runoff. Therefore, present study was carried out estimate runoff erosion using Soil Conservation Service Curve Number (SCS-CN) method RUSLE approach, respectively. These have been estimated geospatial technologies for ungauged Mandri river watershed from Kanker district Chhattisgarh State India. potential zones, which are defined by area's impermeable surfaces given quantity precipitation were identified based on curve numbers at sub-watershed levels. land use data collected LISS IV images 2009. showed that average volume generated throughout 16 years (2000-2015) 14.37 million cubic meters (mM3). While annual found be 17.23 tons/ha/year. Most eroded area around major stream drainage system River higher slopes terrain watershed. This revealed primary issues, adversely affected this suitable harvesting sites structures can constructed zone severity conserve
