Biological Nitrogen Removal in Sediment Plumes: A Critical but Missing Component of Watershed Models

800 532 Stroud Water Research Center

Nutrient export from rivers is closely tied to sediment plumes that form during storms. By using experiments and methods to peer inside these sediment plumes, this project will discover how…

Evaluating How Conventional, Conservation, and Organic Farming Management Practices Enhance Soil Health and Improve Water Quality

800 532 Stroud Water Research Center

This project investigates how different agricultural management practices influence water quality and soil health. Using Rodale Institute’s 37-year-old Farming Systems Trial and a recent transition to organic farming at the…

Evaluating NCRN Data Quality, Revising and Updating Protocols, and Analyzing Long-Term Data

800 532 Stroud Water Research Center

The National Park Service National Capital Region Inventory and Monitoring Network (NCRN) has monitored stream water quality and quantity for more than 15 years in shallow streams located in 10…

Evaluating the Effects of Watershed-Scale Agricultural Best Management Practices on Water Quality

800 532 Stroud Water Research Center

In early 2020, stream bank fencing, forested buffers, and barnyard improvements were installed on Amish farms in Lancaster County, Pa. The farms are nested in a small watershed drained by…

Long-Term Research in Environmental Biology (LTREB): River Ecosystem Responses to Floodplain Restoration

800 532 Stroud Water Research Center

After 25 years of litigation, a massive ecological restoration is under way in the Upper Clark Fork River, Mont. Metal-laden floodplain soils are being removed, floodplains are being reconnected with…

Long-Term Research in Environmental Biology (LTREB): Trajectory for the Recovery of Stream Ecosystem Structure and Function During Reforestation

800 532 Stroud Water Research Center

Stream restoration in the United States is a multibillion-dollar industry, yet long-term monitoring of its effectiveness is virtually nonexistent. To fill this gap, the Stroud Center restored a portion of…

Low-Head Milldams as Hotspots for Denitrification and Nitrogen Consumption: Hydrologic and Biogeochemical Controls

800 532 Stroud Water Research Center

Dam removal, especially low-head milldams, have increased in recent years with the highest removal rate in the mid-Atlantic U.S. While improvement in fish habitat and reduction in financial liability have…
