Abstract The Ogallala aquifer in the Oklahoma Panhandle is in need of better management because of increased groundwater demand which has caused declines in static water levels at an alarming rate. A groundwater management computer model developed for the Ogallala aquifer in the Texas Panhandle treats the aquifer as a homogeneous system. In this study, the computer model has been modified in order to evaluate the effect of vertical layering on semi-static water level changes which occur during the dewatering of a single unconfined aquifer. The modified model was applied to a study area near Guymon, Oklahoma, using both the homogeneous and the multi-layered cases. The aquifer is characterized by a saturated thickness of 400 feet.
