Urbanization and Recharge in the Vicinity of East Meadow Brook, Nassau County,New York, Part 3. Ground-Water Levels and Flow Conditions, 1988-93

摘要

This report describes ground-water levels and flow conditions in the East MeadowBrook headwaters study area before construction of the stormflow-detention basin and during the first year thereafter. It describes (1) the stratigraphy of the upper glacial aquifer at the headwaters study area, (2) ground-water levels and ground-water flow conditions during a dry period and a wet period before stream-channel modification, and (3) the effects of basin construction on water levels and flow conditions. The report includes stratigraphic and hydrologic sections, and regional and local water-level maps.
