Monthly P values came from the PRISM dataset, while monthly ET values were derived from linear transformations of the MODIS daytime land-surface temperature values into pixel ET rates with the help of ancillary atmospheric data (air temperature, humidity, and global radiation). The study area receives about 73mm of recharge (with an error bound of ±73mm) annually, which is about 14 ± 14% of the regional mean annual P value of 533mm. The largest recharge rates (about 200 ± 85mm or 30 ± 12% of P) occur in the south-eastern part of the Sand Hills due to smoother terrain and more abundant precipitation (around 700mm), while recharge is the smallest (about 40 ± 59mm or 10 ± 14% of P) in the western part, where annual precipitation is only about 420mm. Typically, lakes, wetlands, wet inter-dunal valleys, rivers, irrigated crops (except in the south-eastern region) and certain parts of afforested areas in the south-central portion of the study area act as discharge areas for groundwater.
