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.
