Krissy Hopkins is a Research Physical Scientist at the South Atlantic Water Science Center in Raleigh, NC.
Krissy Hopkins studies the impacts of land use change on rivers and streams, focused on understanding how the intensity and type of urban development impact watershed processes. This includes examining the impacts of different types of stormwater management strategies, both conventional and infiltration-based (i.e., green infrastructure), on hydrologic, geochemical, geomorphic, and ecological functions within freshwater ecosystems. Her work also focuses on translating ecosystem functions into ecosystem services and values by applying ecosystem services approaches to floodplain systems and green stormwater infrastructure.

Floodplains provide millions of dollars in benefits every year to people in the Chesapeake Bay and Delaware River watersheds
Issue: Floodplains provide important services to people by retaining sediments, nutrients, and floodwaters, thereby improving water quality and reducing flooding impacts. Having information on how the monetary benefit that floodplains provide varies across the Chesapeake Bay and Delaware River watersheds helps resource managers describe the benefits that floodplains provide in their current state...
Unique 20-year study assesses ecosystem response to different types of stormwater management
Issue: Managing stormwater runoff in developing areas
Raleigh Bank Erosion Project
The City of Raleigh partnered with the U.S. Geological Survey (USGS) to assist in assessing streambank erosion hotspots along the City of Raleigh’s stream network to support the City’s efforts of prioritizing future stream mitigation projects. Streambank erosion potential will be assessed using remotely sensed light detection and ranging (lidar) data, field assessments of streambank conditions...
New dataset available on stream and floodplain geometry to inform restoration decisions
Issue: The need for stream mapping The physical shape of streams and floodplains can provide information about how water, sediment, and other matter moves through the landscape. Streams can have deep channels (tall streambanks) disconnected from the floodplain or wide shallow channels that easily spill over the banks into the floodplain during high flows. Mapping where streams fall along this...
New Insights on using Green Stormwater Infrastructure to Reduce Suburban Runoff
The Issue with Runoff Across the United States, suburban development is replacing agricultural and forested lands. In urban and suburban areas, large amounts of stormwater runoff are generated from rooftops and roadways during rain events. Runoff is quickly piped to streams and rivers, leading to flash flooding, stream bank erosion, and damages to stream health. Reducing nutrients, sediment, and...
SPARROW Modeling for North Carolina Watersheds
In North Carolina, excessive nutrient and sediment loadings have contributed to the degradation of surface-water quality across the state as a result of agricultural activities and population growth increases. To further understand the influences of human activities and natural processes on surface-water quality, the U.S. Geological Survey (USGS) developed the SPARROW (SPAtially Referenced...
Understanding the Effects of Stormwater Management Practices on Water Quality and Flow
Urban development can have detrimental impacts on streams including altering hydrology, increasing nutrient, sediment, and pollutant loadings, and degrading biological integrity. Stormwater Best Management Practices (BMPs) can be used to mitigate the effects of urban development by retaining large volumes of stormwater runoff and treating runoff to remove pollutants. This project focuses on...
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 systems...
