Potential for Saltwater Intrusion in the Potomac Aquifers of the York-James211 Peninsula, Virginia

摘要

The Chloride Project is a cooperative program of the U.S. Geological Survey211u001e(USGS) and the Hampton Roads Planning District Commission (HRPDC) that began in 211u001e1995. The first objective of the Chloride were evaluated with the aid of a two-211u001edimensional, density-dependent, ground-water flow and solute-transport model. The 211u001eUSGS solute-transport model SUTRA (Voss, 1984) was used to represent a simplified 211u001evertical section of the Potomac aquifers and the hydraulic properties of the 211u001eaquifers and associated confining units near Lee Hall, Va. The Lee Hall section 211u001ewas selected because more information about the aquifers and confining units was 211u001eavailable there than elsewhere and because data collected during the prior to the 211u001eChloride Project indicated that saltwater could be moving in the Lower Potomac 211u001eaquifer, but not in the shallower aquifers, near Lee Hall.
