The Delaware River is rich in history, ecologically diverse, and critical to the regional economy. Water managers in this basin have a long history of applying innovative, regional solutions to ensure the long-term sustainability of this treasured resource which provides drinking water to over 15 million people in the region.
Matthew C Gyves
My work focuses on the collection of surface water flow and continuous water quality data. More recently this work has been extended to research the use of using surrogate models to estimate concentrations and loads for several different water quality constituents, including suspended sediment and chloride.
I've participated on several high-water mark and surveying campaigns related to large flood events following severe storms, including Hurricane Maria in Puerto Rico.
CURRENT PROJECTS
- Continuous Nitrate and DOC measurements
- Delaware River Basin Next Generation Observing System (NGWOS)
- Seepage investigations in and around Willow Grove Naval Air Station to identify streamflow losses
Science and Products
Sediment and Stream Health - Pennsylvania
Sediment in streams, from land surface erosion in watersheds, is an important factor in determining the quality of Pennsylvania's surface waters and of downstream water bodies such as the Delaware Estuary and Chesapeake Bay. The USGS has a long-standing tradition of measuring suspended-sediment concentrations and estimating loads. Recent technological advances allow real-time estimates of...
Next Generation Water Observing System: Delaware River Basin
The USGS Next Generation Water Observing System (NGWOS) provides high-fidelity, real-time data on water quantity and quality necessary to support modern water prediction and decision support systems for water emergencies and daily water operations. The Delaware River Basin was the first NGWOS basin, providing an opportunity to implement the program in a nationally important, complex interstate...
Pennsylvania Super Gages
What is a Super Gage? A gage at which continuous flow and water level are determined, along with continuous traditional water-quality (water temperature, specific conductance, pH, dissolved oxygen, and/or turbidity) and either of the following criteria: at least one other less-traditional continuous water-quality parameter (orthophosphate, nitrate concentration) and/or where surrogates (developed...
Streamflow Estimation from Advanced Imaging (LSPIV) in Pennsylvania
Pennsylvania Water Science Center and the Next Generation Water Observing Systems (NGWOS) Program are implementing new technologies for streamflow estimation at sites in Pennsylvania where conventional measurement techniques are inadequate.
Philadelphia Water Resources Monitoring Program
The Philadelphia Water Department (PWD) and USGS have been working together to create and expand the water-quality monitoring network for Philadelphia.
