Quantifying Floodplain Ecological Processes and Ecosystem Services in the Delaware River Watershed

Floodplain and wetland areas provide critical ecosystem services to local and downstream communities by retaining sediments, nutrients, and floodwaters. The loss of floodplain functionality due to land use conversion and degradation reduces the provisioning of these services. Assessing, quantifying, and valuing floodplain ecosystem services provide a framework to estimate how floodplain...

Selected Roadway High-Water Mark Data from Hurricane Joaquin Flooding, October 2015

As part of the statewide response to the flooding, the USGS and S.C. Department of Transportation (SCDOT) conducted a cooperative study to collect high-water mark (HWM) data at 50 selected road crossings.

The HWM elevations and descriptive data have been posted on the USGS Short-Term Network (STN). The STN is a national-...

Determination of Changes in Water Quality, Streambed Sediment, and Benthic Macroinvertebrates as a Result of Stormwater Runoff from Selected Bridges in South Carolina

Past stormwater monitoring has indicated that bridge deck runoff has relatively high concentrations of a variety of constituents such as nutrients, solids, pesticides, trace metals, and polycyclic aromatic hydrocarbons (PAHs). The objective of this investigation is to quantify the downstream changes in receiving water-quality conditions during periods of observable stormwater runoff from...
