Estimation of precipitation recharge coefficient with a GIS-based method in Zhuanlongwan study area, China

Precipitation is the most important recharge source in arid–semiarid studied regions; the detailed effect of rainfall recharge is the main object for consideration. To calculate the precipitation recharge coefficient in region scale, the topography, geography, and climatic data, selected with remote sensing (RS), were visualized in GIS-based methods. Then, the regional precipitation recharge was simulated in the model of WetSpass. With the...
