Delineation of Areas Contributing Recharge to Selected Public-Supply Wells in Glacial Valley-Fill and Wetland Settings, Rhode Island - Usgs Scientific Investigations Report 2004-5070 (Paperback)

Areas contributing recharge and sources of water to one proposed and seven present public-supply wells, screened in sand and gravel deposits and clustered in three study areas, were determined on the basis of calibrated, steady-state ground-water-flow models representing average hydrologic conditions. The area contributing recharge to a well is defined as the surface area where water recharges the ground water and then flows toward and discharges to the well.
