National Research Program | Climate and Disturbance Impacts on Hydrologic Processes

Project Scientists


Our research encompasses a broad spectrum of water resources concerns deriving from climate and disturbance effects. We investigate water, gas, solute, and energy transport in climates ranging from subarctic to arid to equatorial at sites located within the US and internationally. Selected current research topics include:

  1. vulnerability to permafrost thaw and implications for flowpaths, fluxes, and distribution of surface and subsurface waters and carbon transport,
  2. impacts of landscape disturbance on hydrologic processes at plot to watershed scales,
  3. unsaturated zone soil-hydraulic properties and linkages to transport processes, and
  4. resource changes and sustainability strategies associated with the water-energy-food nexus.
