AbstractThis thesis sets forth aquifer conditions in the Catalina Basin, north of Tucson, Arizona. Historically, this area has not experienced significant urban development and no serious attempt has been made to determine either the extent of local groundwater reserves or the potential yield of the Catalina aquifer system. To address these issues, the geology of the basin fill units was defined through the construction and lithologic logging of two test holes, each 1200-feet deep. In addition, test data from three local wells were analyzed to determine that the local aquifer has a transmissivity averaging 50,000 gpd/ft and a specific yield of 15 percent. With this information, the USGS computer program MODFLOW was used to construct a transient state model of the Catalina aquifer system. The model was then employed to compute the expected drawdown throughout the area which would result from full urbanization.
