摘要: This research was conducted to develop relationships among evapotranspiration (ET), percolation (PERC), groundwater discharge the stream (GWQ), and water table fluctuations through a modeling approach. The Soil Water Assessment Tool (SWAT) hydrologic crop models were applied in Big Sunflower River watershed (BSRW; 7660 km(2) ) within Yazoo Basin of Lower Mississippi alluvial plain. Results this study showed good very model performances with coefficient determination (R(2) Nash-Sutcliffe efficiency (NSE) index from 0.4 0.9, respectively, during both calibration validation. An empirical relationship between ET, PERC, GWQ, able predict 64% variation plain study. Thematic maps developed identify areas overuse groundwater, which can help managers resource programs.
