Hydrologic Modeling

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.

To use NJHAT at ungaged sites, an analytical tool is required that can develop a long-term daily hydrograph at these sites. The objectives of the project is to pilot the use of TOPMODEL and DHI software to produce long-term hydrographs at gaged sites and to show that one or both of these models could be used to produce long-term hydrographs at ungaged sites with sufficient accuracy for use with...

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.

As part of the New Jersey Source Water Assessment Program, the U.S. Geological Survey previously developed models to determine the susceptibility of surface water intakes and groundwater supply wells used for public supply. Applying these models presently requires a substantial data-processing effort involving many manual steps. An adaptable, automated process is needed so that NJDEP can update...

Various questions arise on whether or not realistic stream restoration goals can be established with our current understanding of watershed indicators and major controlling factors of aquatic ecosystem health. State-of-the-art statistical, GIS, and hydrologic modeling approaches at multiple levels of data stratification will be extensively used to evaluate the AMNET assessment methodology...

The USEPA wants USGS to evaluate available hydrogeologic and groundwater-quality data to determine if there is sufficient data to develop a model to estimate contributing area of water to the wells. The goals of this project are to determine if available data is sufficient to develop a groundwater flow model to estimate contributing area of water to wells and to determine what data needs to be...

NJDEP, in cooperation with the Passaic TMDL Work Group, has determined that riverine water quality modeling of phosphorus and nitrogen in the Passaic River basin will be required to support several TMDL efforts underway. Water quality in the Passaic River basin is affected by complex river system hydraulics, groundwater-surface water interactions, non-point source runoff from mixed land uses and...

The Galloway research team has developed and documented three computer programs for simulating flow and transport in the unsaturated zone that are available to the public. These programs were funded by the Toxics Substances Hydrology Program. The computer codes are written in Fortran F77 and run on a variety of computer systems, including mainframe and personal computers, with only minor...

The research site is located approximately 15 miles northwest of Atlantic City, New Jersey.
