Dr. Thompson’s research in stream and wetland restoration focuses on the role of vegetation in flow resistance and streambank erosion resistance, mitigating the impacts of urban development on stream systems, and predicting the onset and rate of streambank erosion. Recent research documented the critical role of woody vegetation roots and soil microorganisms in increasing soil erosion resistance.  This research informed recent changes in levee management recommendations from the US Army Corps of Engineers, allowing the growth of native riparian vegetation along the nearly 30,000 miles of levees in the United States.  

Dr. Thompson’s current research explores the impact of different stormwater regulations on stream channel stability.  Results of this work showed that regulations focused on detaining a given volume of runoff do not protect streams against erosion following urban development.  This research also demonstrated that, to protect the physical integrity of streams, stormwater management systems must be designed considering changes in stream sediment transport, particularly given increasing rainfall intensity due to climate change.
