Interests and Expertise

Marc Peipoch is interested in the effects of nutrient pollution on aquatic biodiversity and nutrient cycling in freshwater ecosystems. His research focuses on the interactions among ecological and biogeochemical processes that drive aquatic ecosystem dynamics, and uses a diverse set of tools including field experiments, water quality sensors, and modeling approaches.

Specific projects that address these research interests include studies of nutrient spiraling in “pristine” and polluted streams, the influence of low-head milldams on water quality, biological nutrient removal within sediment plumes in agricultural streams, restoration of habitat complexity and ecosystem services in river floodplains, algal growth and nutrient uptake in large rivers, and causes and consequences of riverine algal blooms.

Most of his work has been done and continues to be in streams and rivers of the Piedmont region, the Rocky Mountains and Great Plains of Montana, and/or the Mediterranean Basin.

We’ve Missed This! Stroud Center Resumes Fish Monitoring

It feels like a breath of fresh air for our research staff to resume our fish monitoring project in 37 streams of the Washington, D.C. metropolitan area.

A Small Farm Offers Big Opportunities for Measuring Watershed Restoration Success

Stream restorations rarely get monitored rigorously enough to determine if the “patient” has fully recovered.

Patience is the Mother of Science: Long-Term Responses of a Stream to Reforestation

We're studying how White Clay Creek can recover from deforestation and agricultural expansion and to what extent restoration practices can acclerate that recovery.

Stream Reach: Building Communities from White Clay Creek to the Yangtze Basin

To truly make a difference requires, not only understanding freshwater systems, but working with all kinds of communities to protect them.

Don’t Stop Me Now! Studying the Effects of Milldam Removal

Stroud Water Research Center scientists are investigating how milldam removal might affect groundwater and surface water quality.
