Dynamics of Organic Particles in River Ecosystems

800 532 Stroud Water Research Center

Suspended organic particles are important to river food webs and in the transfer of organic carbon from land to ocean. In an experiment conducted in Stroud Water Research Center’s streamside…

Hydrologic Regulation of Dissolved Organic Matter Biogeochemistry From Forests Through River Networks

800 532 Stroud Water Research Center

This collaborative proposal will generate the mathematical models that simulate stream flow in White Clay Creek and the movement of water carrying dissolved organic carbon from soils to the stream.…

The Application of Scaling Rules to Energy Flow in Stream Ecosystems

800 532 Stroud Water Research Center

Scientists have grown young deciduous trees in an atmosphere enriched with the stable isotope of carbon so as to follow the fate of those organic molecules in small laboratory reactors,…

Scaling the gas transfer velocity and hydraulic geometry in streams and small rivers

350 210 Stroud Water Research Center

Raymond, P.A., C.J. Zappa, D. Butman, T.L. Bott, C. Potter, P. Mulholland, A.E. Laursen, W.H. McDowell, and D. Newbold. 2012. Limnology and Oceanography: Fluids and Environments 2:41–53.

Abandoned Mine Drainage Remediation and Stream Function

800 532 Stroud Water Research Center

This study was designed to determine the impact of abandoned mine drainage (AMD) on stream ecosystem functions, such as algal growth, nutrient spiraling, litter decay, and enzyme function, as well…

Connecting the Hydrologic Cycle From Hillslopes to River Networks

800 532 Stroud Water Research Center

This collaborative research will generate the first model that links the water and carbon cycles of river catchments by focusing on the interactions of water movement and organic carbon in…

The Importance of Streamside Reforestation for Reducing Nonpoint-Source Pollution in Small Streams

800 532 Stroud Water Research Center

This ongoing project to track water quality improvements provided by a riparian forest buffer in the Stroud Preserve, Chester County, Pennsylvania, indicates that 15 years after planting, the buffer reduced…

Long-Term Research in Environmental Biology (LTREB): Stream Ecosystem Structure and Function in a Maturing Deciduous Forest

800 532 Stroud Water Research Center

This project addresses long-term changes in a stream ecosystem in southeastern Pennsylvania to evaluate best management practices for riparian or streamside lands and provide a time frame for ecosystem recovery…
