Advanced Capabilities and Data Visualization

Frequently, water withdrawals for public supply are made from the freshwater reaches of rivers and streams across new Jersey. Overall, there is a lack of scientific information describing the movement of saltwater upstream into the tributaries discharging into Delaware Bay. This project is beginning to collect water quality data along three selected tributaries in New Jersey to Delaware Bay in an...

The Coastal Plain aquifers of New Jersey provide an important source of water for more than 3.5 million people. The USGS, in cooperation with the New Jersey Department of Environmental Protection, has been measuring water levels in the confined aquifers of the New Jersey Coastal Plain every five years beginning in 1978. Persistent, regionally extensive cones of depression are present in Ocean and...

The New Jersey Water Science Center provides valuable data augmentation to many locations for: Precipitation, Water and Air Temperature, and even Wind Speed and Direction at some of our coastal sites. Our technicians continuously make field measurements and maintain these networks to ensure the accuracy of these data.

To better protect the City of Elizabeth’s residents and assets, the U.S. Geological Survey (USGS) and Rutgers University proposed a joint collaboration to develop a reliable flood risk management platform with the cooperation of the City of Elizabeth and the New Jersey Office of Emergency Management. Our understanding is the broader goal for the City of Elizabeth is to accomplish three primary...

The USGS operates the most extensive network of tide-gaging stations in the region, many of which form the backbone of flood-warning and storm-hazard warning systems. The New Jersey Water Science Center monitors data for estuary and back-bay areas all along the New Jersey coast and links to related projects with more information about coastal flood hazards, water quality, and other topics. This...

The Flow Photo Explorer (FPE) is a database, machine learning, and data visualization platform using timelapse images to develop new approaches for collecting hydrologic data in streams and other waterbodies where traditional monitoring methods are not feasible or cost-prohibitive. The Musconetcong River was chosen to participate in the early study, and we are expanding the work to other rivers.

Understanding the quality of U.S. streams, rivers, and groundwater requires consistent data collection and analysis over decades for proper context of current conditions. The USGS collects nationally standardized data and information as part of the National Water Quality Network (NWQN). The NQWN is made up of sites across the Nation where USGS scientists regularly measure water-quality conditions.

This project seeks to develop methods to identify when a flooded roadway or bridge crossing condition may exist and to provide a tool for users to select rainfall scenarios in addition to the selected river condition to estimate if road flooding may occur with the selected combination. These tools will provide officials in Hunterdon County and at the state level of management better early warning...

Static webcams have been installed at a number of real-time stream-gaging locations in New Jersey to allow you to view the current river-stage conditions. These webcams provide valuable information to the National Weather Service, emergency managers, and area residents to evaluate real-time conditions in river and coastal environments during storms.

Manning’s Roughness Coefficient (n) is an input to the Manning’s Equation, which can be used for the computation of streamflow during times it is impractical or impossible to make a measurement. ​ Methods and regional equations for determining the value of n have largely been developed in the western United States; New Jersey is comparatively unstudied. New Jersey features a diverse range of...

As part of the Urban Water Federal Partnership, the U.S. Geological Survey (USGS) New Jersey Water Science Center (NJWSC) is currently assessing the use of innovative, near real-time bacteria monitoring technology to provide rapid results on bacteria concentrations to water regulators. Traditional methods of collecting and quantifying fecal indicator bacteria (FIB) is labor intensive, expensive...

The temperature, water quality, and channel connectivity along headwater stream networks often show highly dynamic spatiotemporal patterns that are tied to localized hydrogeologic and landcover controls. Groundwater exchanges exert a spatially discontinuous influence on streams that reflect, in part, the preferential nature of groundwater discharge as controlled by recharge, topography, and...
