To understand the effects of projected increased demands on ground water to supply water, a finite-difference, steady-state, nine-layer, groundwater flow model was used to simulate groundwater flow in the Coastal Plain sediments of southern New Castle County, Delaware. Results are published in DGS RI77

The Delaware DataMIL collects, maps, and serves Delaware's Spatial Data Framework, or basic map datasets, on which state agencies, local and county governments, academic GIS users, and the private sector can use for their own needs. DataMIL also provides access for Delaware topographic maps that replace the old USGS 7.5-minute topographic maps for the State.
