Hydrodynamic Flow

The Model Maintenance program, in cooperation with the N.J. Department of Environmental Protection (NJDEP), archives, maintains, updates, and shares groundwater-flow models that have been developed by the New Jersey Water Science Center (NJWSC). The program was started in 1995 to maintain existing groundwater flow models, use standardized procedures to archive the models, update models with recent...

The Current Period Streamflow Statistics project is computing low flow statistics for both a historic (1950-1979) and more recent (1990-2019) 30-year period. The computed statistics will provide information about streamflow changes over time and an evaluation of more recent streamflow conditions. The project will also present land-use changes, precipitation patterns, and water use in the...

NJDEP has determined that water quality modeling of the Salem River is necessary for a nutrient (phosphorus) TMDL. However, little background data is available for the basin. Intensive field monitoring was commenced by the U.S. Geological Survey (USGS) for the NJDEP in 2007 to support understanding of the nutrient loading processes in basin as well as to provide the input data to the flow and...

Groundwater budgets are commonly used in water-resource studies to gain a better understanding of the groundwater-flow system. The hydrologic cycle in the basin can be represented by a long-term water budget in which inflows are balances by outflows and, thus, no long-term change in storage occurs. The water budget can be evaluated through use of two internal budgets and their corresponding...

The State of New Jersey strives to allocate water resources to meet human demands and ecological needs. The New Jersey Water Transfer Data Model (NJWaTr) is a database system that compiles, stores, and distributes New Jersey’s water use data for research and modeling purposes. NJWaTr helps officials understand the movement and uses of water throughout the State over time.

The development of hydrodynamic and water-quality models is proposed to provide NJDEP with the necessary analytical capability to address critical management issues relating to water quality and eutrophication in the Barnegat Bay-Little Egg Harbor Estuary. The primary objectives of this proposed study are to examine the water-quality causes of eutrophication in the BB-LEH Estuary and evaluate...
