Water Harvesting Potential Prediction for Budelkani Watershed for design of Runoff Recycling Irrigation Pond

Water harvesting potential was simulated for Budelkani watershed of Sundargarh district, Odisha, India, predicted using water balance model. Model was simulated for 23 years (1983-2015) for short duration variety of rice (108 days). Simulation was done in two variations, firstly in seasonal basis, secondly stage wise. At 50% PE, for 50 mm PWL, SR, rainfall, SI and WHP were best fitted at 120.13 mm, 1144.1 mm, 91.96 mm and 1.52 respectively. They were best fitted by Log-pearson, pareto, EV Type III and pareto respectively. Similarly stage wise, SR also more in stage 1 than stage 2 at quantity of 66.54 and 7.55 mm, respectively and there WHP were calculated to be 1.31. At 50% PE, seasonal values of SR, WHP and SI recorded at 66.23 mm, 1.1 and 79.03 mm, for 100 mm PWL, respectively. They were best fitted by Gamma, Log-pearson and Log normal, respectively. While stage wise, SR at 50% PE were found to be 32.57 to 16.99 mm for stage 1 and stage 2 and WHP at 50% PE, found to be 1.01 in 100 mm PWL. Log-pearson, EV Type III and Log-normal (3-P) PDF were best fitted to SR, WHP and SI at seasonally for 150 mm PWL. At 50% PE, SR, WHP and SI value lies at 65.94 mm, 1.02, 67.72 mm. For 150 mm PWL, best fitted values of SR at 50% PE, for stage 1 and stage 2 were observed to be 15.3 mm, 12.32 mm and likewise, WHP found to be 1.
