The ground-water budget of the unconsolidated deposits in the upper Wabash River basin was modeled. An electrical-simulation network was used to determine an integrated storage coefficient of 0.003 for the basin. Two practical problems were investigated: a municipal pumping problem and the change in flow regime due to the addition of surface-water reservoirs to the basin. Because these are demonstration exercises, the information presented is not intended to be used for construction justification. The network is available and can be used to determine the effect on basin hydrology due to local development of the ground-water resource.
