dc.description.abstractEnglishA Soil and Water Assessment Tool (SWAT) model was developed for the Independence Basin, a watershed of around6,992.00 km2 with significant seasonal climate in the semi-arid highland of central Mexico, Guanajuato state. This area is dominated by agricultural land cover (43.32%) and followed by pasture (25.70%). This study aims to evaluate the historical variation of water resources and the impacts of future climate change on the hydrologic regime of the Independence Basin. Thus, the Independence Basin was divided into 36 sub-basins by ArcSWAT (Version 2012) and calibrated with 2 gauging stations and 2 reservoirs data sets with the aid of the SUFI-2 algorithm assembled in SWAT-CUP. Hydrological responses to future climate change have been analyzed under conditions of RCP 4.5 emission scenario and RCP 8.5 emission scenario generated by 7 General Circulation Models (GCMs) for the mid-century period (2030-2059) and for the end of this century (2070-2099), respectively. In modeling the stream flow, results from good to very-good fit level with R2 (0.66~0.89) and Nash–Sutcliffe efficiency (NSE) (0.65~0.88) have been obtained for both the calibration and the validation periods, while the PBIAS was not as good as the former indicators but nevertheless very-good to satisfactory results were obtained. Five of those parameters: CN2, SOL_K, SOL_AWC, GWQMN and SOL_Z are sensitive in descending order in the Independence Basin model, indicating that the groundwater system plays an important role in the hydrologic regime. The historical water budget analysis of a 40-years period of 1970-2009 showed that the annual precipitation was about 495.10 mm, while PET, ET, deep aquifer recharge and surface runoff were 1670.00 mm, 471.30 mm, 39.08 mm and 33.38 mm, respectively. The estimated groundwater extraction was lower than the real case, indicating that the drawdown of aquifers has been worsened in recent years. According to the projections of 7 GCMs.es_MX
