2012 SPARROW Models for the Northeast: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow

The 2012 SPAtially Referenced Regression On Watershed attributes (SPARROW) Models measure the damaging contaminants of phosphorus, nitrogen, and suspended sediment in streamflow throughout the Northeast United States. Through various types of watershed management practices, loads of nutrients and suspended sediment are significantly reduced within the stream network in impounded reaches, and...

MD-DE-DC WSC Water Use & Water Supply Capabilities

In Maryland, public supply water is delivered to users for domestic, commercial, and industrial purposes. Most is used for public services, such as public pools, parks, firefighting, water and wastewater treatment, and municipal buildings, and some is unaccounted for because of leaks, flushing, tower maintenance, and other system losses. 5.7 million Marylanders get their water from the public...

MD-DE-DC WSC Geomorphology and Sediment Studies Capabilities

Geomorphology is classified as the study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near the Earth's surface. Adding water creates a whole new dynamic known as Fluvial Morphology. Rivers and streams act as conduits of water along with sediment. As water flows over the channel bed, it is able to...

MD-DE-DC WSC Modeling Capabilities

USGS models are widely used to predict responses of hydrologic systems to changing stresses, such as increases in precipitation or ground-water pumping rates, as well as to predict the fate and movement of solutes and contaminants in water.

The USGS is at the forefront of devising new techniques and computer software to solve practical problems in the study of water resources....

MD-DE-DC WSC Laboratory Capabilities

The labs at the MD-DE-DC WSC are clean, well-stocked, and appointed with modern equipment and a highly talented staff.  The three labs analyze samples, conduct controlled-environment chemical tests with GCMS in the Water Qualty lab. Scientists and technicians work with core samples and analyze soils in the Sediment Lab.

Our labs assure reliability, reproducibility, and high quality of...

MD-DE-DC WSC Water Quality Capabilities

Water quality is a measure of the suitability of water for a particular use based on selected physical, chemical, and biological characteristics. Water-quality monitoring is used to help water-resource managers understand and avert potential negative effects of man-made and natural stresses on water resources, evaluate trends, and compare to water-quality criteria.

One of our primary...

MD-DE-DC WSC Surface Water Capabilities

As an integrated part of the WSC, the Surface Water Team monitors and conducts investigative research to describe and improve our region's understanding of extreme hydrologic events - droughts, floods and flood hazards, and coastal or bay storm surge and inundation. They also facilitate measurement stream stages, streamflow, and computes daily streamflow at locations in Maryland, Delaware, and...

The Response of Coastal Wetlands to Sea-level Rise: Understanding how Macroscale Drivers Influence Local Processes and Feedbacks

The purpose of this work is to advance our understanding of how coastal wetland responses to sea-level rise (SLR) within the conterminous United States are likely to vary as a function of local, regional, and macroscale drivers, including climate. Based on our interactions with managers and decision makers, as well as our knowledge of the current state of the science, we propose to: (a)...

Effects of Short Chain Chlorinated Paraffins (SCCPs) on developing birds

The Challenge: Short-Chain Chlorinated Paraffins (SCCPs) are complex technical mixtures of polychlorinated n-alkanes used in lubricants and coolants in metalworking, as flame retardants, and in paints, adhesives, sealants, textiles and polymeric materials, plastics and rubber. SCCPs are of concern because they are globally transported, bioaccumulate in wildlife and humans, and are...
