Water Budgets

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 future health and welfare of the Nation's population and environment are dependent upon a continuing supply of uncontaminated fresh water. Increasing withdrawals and increasing demands for in-stream flows are limiting the water available for future use.

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.

Streamflow data collection and analysis are a necessary component of effective water resource management and planning. Low-flow statistics are needed to safely allow withdraws from and discharges to surface waters in the State of New Jersey. Operating streamflow gaging stations at every water use location would be ideal but is cost prohibitive. Statistics help extend the utility of available data...

Development of water supply is a dynamic condition, and demand areas may shift, or quality or quantity concerns may change in a former study area. This program will address the need of the N.J. Department of Environmental Protection (NJDEP) to understand the possible effects of proposed or planned withdrawals within these previously studied areas. The general objective of this program is to...

In the New Jersey Coastal Plain, where confined aquifers provide over 200 million gallons per day, effective water resource planning and management under increasingly complex circumstances requires a current and improving understanding of the limitations of the available water from confined aquifers, the interconnections between confined and unconfined aquifers, and the sources of flow to critical...

Demand for water in the southeast New Jersey area is expected to increase as growth continues in the area. Supplying these demands while maintaining adequate streamflow and protecting the long-term resources in the Atlantic City 800-foot sand will require effective water resource management.

The County of Monmouth recently purchased a parcel of land in a rapidly urbanizing area of Monmouth County, New Jersey. The Monmouth County Park System (MCPS) in partnership with the Manasquan River Watershed Association (MRWA) plans to return the land to a more natural state and has received funding from the New Jersey State Wetlands Mitigation Council for a stream restoration project on an...

The NJDEP is conducting a Water Supply Assessment of Northeast NJ and would like the District to help in that assessment, provide modeling tools to project flows, and provide technical assistance. The goals of this project are associated with water supply within the region.

The hydroecological integrity assessment process (HIP) has been fully developed for the State of New Jersey (NJHIP). The New Jersey Department of Environmental Protection is in the process of applying ecologically relevant ecological flow goals (ERHI's) from the NJHIP to current and future regulation of New Jersey streams. It is the goal of NJDEP to evaluate potential impacts of a proposed water...

The recent 4-year joint USGS/NJDEP research project 'Ecological Flow Goals' has resulted in the New Jersey Hydrologic Assessment Tool (NJHAT). This analysis software determines streamflow characteristics and variability based on a daily hydrograph. The objectives of the project is to identify a series of baseline hydrographs for surface water gaging stations with greater than 20 years of flow...
