MODFLOW-2000 and MODPATH4 used to simulate groundwater flow and contaminant transport in the Pohatcong Valley, Warren County, New Jersey MODFLOW-2000 and MODPATH4 used to simulate groundwater flow and contaminant transport in the Pohatcong Valley, Warren County, New Jersey
The U. S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, developed a numerical groundwater flow model, using MODFLOW2000, to simulate groundwater flow in the Pohatcong Valley including the area within the Pohatcong Valley Ground Water Contamination Site. In 1978, the chlorinated solvents trichloroethene (TCE) and tetrachloroethene (PCE) were detected in...
SEAWAT, MODFLOW-2000, and SHARP models used to simulate future water-supply scenarios, Cape May County, New Jersey SEAWAT, MODFLOW-2000, and SHARP models used to simulate future water-supply scenarios, Cape May County, New Jersey
Three groundwater flow models, using MODFLOW-2000, SEAWAT, and SHARP model codes, were used to evaluate plans to supply potable and non-potable water to residents and businesses of Cape May County, New Jersey until at least 2050. The ideal plan would meet projected demands and minimize adverse effects on currently used sources of potable, non-potable, and ecological water supplies. The U...
MODFLOW-2005 model used to simulate water-table response to climate-change-driven sea-level rise and changes in recharge, Gateway National Recreation Area, Sandy Hook Unit, New Jersey MODFLOW-2005 model used to simulate water-table response to climate-change-driven sea-level rise and changes in recharge, Gateway National Recreation Area, Sandy Hook Unit, New Jersey
A MODFLOW-2005 model, using the SWI2 package, was developed for the Sandy Hook Unit, Gateway National Recreation Area (hereafter Sandy Hook) in New Jersey to evaluate the response of groundwater resources to expected sea-level rise (SLR) and changes in groundwater recharge associated with global climate change. The National Park Service (NPS), among other agencies, is mandated to...
High-water marks in New Jersey following Hurricane Ida and associated floods, September 2021 High-water marks in New Jersey following Hurricane Ida and associated floods, September 2021
The data contained within include high-water marks collected at 50 sites throughout the regions of New Jersey affected by significant flooding from Hurricane Ida during September of 2021. Each site contains between one to six associated high-water marks that were documented, photographed, and surveyed to datum. The datum represented by the elevations of the high-water marks is the North...
Nitrogen sources to and export from the Chesapeake Bay watershed, 1950 to 2050 Nitrogen sources to and export from the Chesapeake Bay watershed, 1950 to 2050
This U.S. Geological Survey data release contains datasets that combine past data with future projections of nitrogen sources and nitrogen export to the Chesapeake Bay watershed for the years 1950-2050. To help understand the effect of human and environmental changes over this time period, data for nitrogen sources from wastewater, agricultural fertilizer and manure, and atmospheric...
Estimates of atmospheric inorganic nitrogen deposition to the Chesapeake Bay watershed, 1950-2050 Estimates of atmospheric inorganic nitrogen deposition to the Chesapeake Bay watershed, 1950-2050
Reactive nitrogen is transported from the atmosphere to the landscape as wet and dry deposition that contributes to annual nitrogen loads to the Chesapeake Bay. Estimates of atmospheric inorganic nitrogen deposition to the Chesapeake Bay watershed during 1950 to 2050 are presented, and are based on field measurements, model simulations, statistical relations, and surrogate constituents...
