Jennifer Murphy

Jenny is a hydrologist with the USGS, Central Midwest Water Science Center. Much of her work focuses on characterizing and understanding water-quality trends in the Nation's streams and rivers. Jenny also leads a team of scientists working to develop a proxy for harmful algal blooms in rivers.

Jenny has played an important role is characterizing water-quality trends with the Weighted Regressions on Time, Season and Discharge (WRTDS) model at >1,000 sites across the country using an extensive multi-agency dataset. Jenny's additional trends work includes looking at nitrate in the Mississippi River Basin, sediment in the lowermost Mississippi and Atchafalaya Rivers, and water quality in streams and rivers in the Delware River Basin. Additionally, Jenny has worked on projects ranging from the evaluation of best management practices in small agricultural drainages, to characterizing and understanding ecological flows, estimating water use at thermoelectric powerplants, and harmonizing multisource data.  Her current interests are in trend studies, causal attribution of these trends, and exploring the influence of streamflow on water quality.
