Watersheds are complicated ecosystems in which many simultaneous natural and human disturbances occur, potentially deteriorating surface and ground water resources. We work at a range of landscape scales to advance our understanding of the implications of those changes for drinking water, wastewater, and stormwater treatment.

Some of our projects include:

  • Wildfire impacts on water quality and drinking water treatability

  • Global mapping of wildfire-water risk

  • Forest management impacts on water quality and drinking water treatability

  • Sediment and associated contaminant source apportionment

  • Post-disturbance watershed-scale nutrient dynamics and downstream transport for assessing algal bloom risks

  • Simulating sediment transport processes in model rivers (annular flumes)

  • Modeling sediment and nutrient dynamics in drinking water reservoirs: links to microbial population shifts and algal bloom risk

  • Mitigating groundwater contamination from road salt by implementation of best management practices
