- The Manikpur coalfield is 300 km2 and is in the Korba district of the Indian state of Chhattisgarh. In India, one of the most severe issues is soil erosion. Calculating exact soil erosion over a specific time is extremely difficult. Huge quantities of mining waste are typically released as over burden dump (OBD) materials by opencast mines. They impact agriculture since they are prone to soil erosion, sedimentation, and poor water quality. An empirical equation of the Revised Universal Soil Loss Equation (RUSLE) and the Sediment Delivery Distributed Model (SEDD) were employed to quantify soil erosion and sediment yield. The findings of these equations were contrasted to those of direct field measurements obtained around the opencast region utilizing an appropriate suspended sediment sampler. The maximum soil erosion value obtained is 79.2 tons/ha/year, and the maximum sediment yield is 57.92 tons/ha/year, according to the findings of this study. The sediment load values from these two models follow the same trend. These models were evaluated for performance and found to be effective, with values of simulated and observed sediment yields R2 = 0.81 and RRMSE = 0.66. The observations revealed that most of the area has a low slope gradient. The opencast mine and overburden dump area have a slight erosion potential due to the higher slope inclination. According to the study, GIS is an effective tool for modelling soil erosion potential and sediment output.
