GSFLOW model to evaluate the effect of groundwater pumpage and climate stresses on the integrated hydrologic system of the Yucaipa subbasin, Yucaipa Valley watershed, San Bernardino and Riverside Counties, California.
A three-dimensional, GSFLOW model was developed to simulate and quantify the hydrologic 
system of the Yucaipa subbasin. The model was calibrated to conditions from 1970 to 2014, the 
period for which data are most complete and reliable. The model was used to (1) quantify the 
effects of historical and potential …
