Résumé partiel
The water availability is limited but the demand of water is increasing fast due to growing population, rapid industrialization, rapid urbanization, and economic development. Therefore, available water resources need to be managed properly to meet increasing demands of water. In the present study, different hydrological processes were modeled to assess the water availability in the Bada khera ravinous watershed located in South-Eastern Rajasthan in order to develop a proper water utilization plan. The daily surface runoff was estimated using NRCS-CN (table) method, NRCS-CN (optimized) method, NAPI method and IHACRES model. The performance of all these methods was evaluated on the basis of statistical parameters like Root Mean Square Error (RMSE), Coefficient of Determination (R2 ), Relative Bias (RB) and Nash-Sutcliffe Modeling Efficiency (E). The daily potential and actual groundwater recharge in the watershed were estimated using unsaturated flow model HYDRUS 1D and Water Table Fluctuation (WTF) method respectively. The daily potential groundwater recharge, volumetric water balance components and water availability in the farm pond was assessed using Dynamic Potential Groundwater Recharge Simulation (DPGRS) model. The results revealed that for the estimation of surface runoff the IHACRES model was found better than other methods.
