| Abstract | Point estimates are among the most widely used methods in estimation of the amount of recharge of groundwater. However, for precise quantification of the spatiotemporal variability of groundwater, a flexible and reliable method was needed. This study aimed to estimate the water balance components in the Hashtgerd plain using WetSpass water balance model, which is spatially distributed. Relevant input data for the model (e.g., rainfall, air temperature, soil, groundwater level, and slope) were gathered and transformed into digitized maps. In this research, an overview of the use of WetSpass model on the quantification of groundwater recharge has been presented. The obtained results from simulations have shown that the average runoff produced in Hashtgerd basin equals to 37.7 mm/year. Also, the maximum amount of runoff, produced by the areas with bare soil plus plants coverage and residential areas in cities and villages. Annually estimated evapotranspiration (ET) amount was equal to 352 mm/year. Moreover, annual recharge during warm and cold seasons was equal to 1% and 99% of the total yearly recharge in this basin, respectively. Finally, the results showed that the WetSpass could model all parts of groundwater components. Moreover, it can be an excellent tool to determinate the areas that there is recharge groundwater potential over there. |
