Simulation of flow and eutrophication in the central Salem River, New Jersey Simulation of flow and eutrophication in the central Salem River, New Jersey
The central Salem River in New Jersey is subject to periods of water-quality impairment, marked by elevated concentrations of phosphorus and chlorophyll-a, and low concentrations of and large diurnal swings in concentrations of dissolved oxygen. These seasonal eutrophic conditions are controlling factors for water quality in lower reaches, where the river is more lacustrine than in upper...

Towards a comprehensive water quality modeling of Barnegat Bay: Development of ROMS to WASP Coupler Towards a comprehensive water quality modeling of Barnegat Bay: Development of ROMS to WASP Coupler
The Regional Ocean Modeling System (ROMS) has been coupled with the Water Quality Analysis Simulation Program (WASP) to be used in a comprehensive analysis of water quality in Barnegat Bay, New Jersey. The coupler can spatially aggregate hydrodynamic information in ROMS cells into larger WASP segments. It can also be used to resample ROMS output at a finer temporal scale to meet WASP...

Analysis of Effects of 2003 and Full-Allocation Withdrawals in Critical Area 1, East-Central New Jersey Analysis of Effects of 2003 and Full-Allocation Withdrawals in Critical Area 1, East-Central New Jersey
Critical Area 1 in east-central New Jersey was mandated in the early 1980s to address large drawdowns caused by increases in groundwater withdrawals. The aquifers involved include the Englishtown aquifer system, Wenonah-Mount Laurel aquifer, and the Upper and Middle Potomac-Raritan-Magothy aquifers. Groundwater levels recovered as a result of mandated cutbacks in withdrawals that began...

Water levels in the Potomac-Raritan-Magothy aquifer system within Water Supply Critical Area 2 in the southern New Jersey Coastal Plain have recovered as a result of reductions in ground-water withdrawals initiated in the early 1990s. The Critical Area consists of the depleted zone and the threatened margin. The Potomac-Raritan-Magothy aquifer system consists of the Upper, Middle, and...

Recovery of Ground-Water Levels From 1988 to 2003 and Analysis of Potential Water-Supply Management Options in Critical Area 1, East-Central New Jersey Recovery of Ground-Water Levels From 1988 to 2003 and Analysis of Potential Water-Supply Management Options in Critical Area 1, East-Central New Jersey
Water levels in four confined aquifers in the New Jersey Coastal Plain within Water Supply Critical Area 1 have recovered as a result of reductions in ground-water withdrawals initiated by the State in the late 1980s. The aquifers are the Wenonah-Mount Laurel, the Upper and Middle Potomac-Raritan-Magothy, and Englishtown aquifer system. Because of increased water demand due to increased

Simulation of Surface-Water Conditions in the Nontidal Passaic River Basin, New Jersey Simulation of Surface-Water Conditions in the Nontidal Passaic River Basin, New Jersey
The Passaic River Basin, the third largest drainage basin in New Jersey, encompasses 950 mi2 (square miles) in the highly urbanized area outside New York City, with a population of 2 million. Water quality in the basin is affected by many natural and anthropogenic factors. Nutrient loading to the Wanaque Reservoir in the northern part of the basin is of particular concern and is caused...

Surficial Aquifer Studies
The series of surficial aquifer studies were completed to evaluate the unconfined aquifer system of the NJ Coastal Plain for use as a potential source of water. As the demand for water in the State increases and the restrictions continue on the use of water from certain confined aquifers, withdrawals on the unconfined aquifer system are expected to increase. Detailed study of the unconfined...
WASP model used to simulate flow and eutrophication in the central Salem River, New Jersey WASP model used to simulate flow and eutrophication in the central Salem River, New Jersey
A one-dimensional surface-water quality model of the central Salem River Basin, New Jersey was developed to examine the causes of eutrophication and predict the effects of reduced point and nonpoint source nutrient loads on water quality. The model was developed using the USEPA WASP code. The model simulates channel flow and the fate and transport of dissolved oxygen, oxygen demands...
