Comparison of vertical discretization techniques in finite-difference models of ground-water flow; example from a hypothetical New England setting Comparison of vertical discretization techniques in finite-difference models of ground-water flow; example from a hypothetical New England setting
Proper discretization of a ground-water-flow field is necessary for the accurate simulation of ground-water flow by models. Although discretiza- tion guidelines are available to ensure numerical stability, current guidelines arc flexible enough (particularly in vertical discretization) to allow for some ambiguity of model results. Testing of two common types of vertical-discretization...

Geohydrology of, and simulation of ground-water flow in, the Milford-Souhegan glacial-drift aquifer, Milford, New Hampshire Geohydrology of, and simulation of ground-water flow in, the Milford-Souhegan glacial-drift aquifer, Milford, New Hampshire
Hydrogeologic data collected since 1990 were assessed and a ground-water-flow model was refined in this study of the Milford-Souhegan glacial-drift aquifer in Milford, New Hampshire. The hydrogeologic data collected were used to refine estimates of hydraulic conductivity and saturated thickness of the aquifer, which were previously calculated during 1988-90. In October 1990, water levels...

Description and results of test-drilling program at Picatinny Arsenal, New Jersey, 1982-84 Description and results of test-drilling program at Picatinny Arsenal, New Jersey, 1982-84
Picatinny Arsenal, located in north-central New Jersey, has a long history of explosives manufacturing. Past industrial activities and past waste-disposal practices have caused some groundwater contamination problems. In 1982, the U.S. Geological Survey, in cooperation with the U.S. Army, began a water resources investigation of the Arsenal. The test drilling program is designed to...

Ground-water-quality data for Picatinny Arsenal, New Jersey, 1958-85 Ground-water-quality data for Picatinny Arsenal, New Jersey, 1958-85
The water resources of Picatinny Arsenal in northern New Jersey are described using the results of 1,129 analyses of groundwater , including 522 determinations of inorganic constituents and 607 determinations of organic constituents. Water samples were collected from 56 wells on the site from 1958 through 1985. Of these wells, 50 are screened in stratified drift aquifers and 6 are in...
