Welcome to the Watershed Processes Lab.   Our research is multidisciplinary and seeks to investigate the interactions between fluvial geomorphology, hydrology, and ecology at multiple scales ranging from individual stream reaches through small catchments up to the whole continent!  Our research strategy incorporates both field-based studies and data modeling utilizing detailed laboratory analysis such as water stable isotopes, streambed grain size distribution analysis, or benthic chlorophyll a concentrations. 


The idea is to find how the physical landscape influences the interactions among different components of the ecosystem. Some of the questions we are interested in answering are:How does water aggregate in space and time within a watershed? 

  • What are the effects of climate change and land cover type on hydrologic flow paths?
  • What are the relations among sediment transport, water quality, and stream ecology?
  • How does the frequency and intensity of extreme hydrologic events change due to climate change?

The ultimate goal is to build predicting models of ecosystem response to human and natural disturbances that provide information to society and allow better adaptation and conservation of natural resources
