Research in the Biggs Lab in the Geography Department of San Diego State University focuses on human interactions with watershed processes, including water balances, sediment budgets, channel morphology, water quality and feedbacks on land use in urban and agricultural landscapes.  Current study sites include the US-Mexico Border region, San Diego, American Samoa, and the Amazon basin.

We aim to integrate three techniques in our research:

  • Remote sensing of land cover change, evapotranspiration, and terrain
  • Modelling, including statistical and dynamic computational models of runoff, sediment, channel form and water quality
  • Fieldwork for characterization of channel geometry, streamflow, and water quality including use of stable isotopes of water for tracing sources and pathways of water in the landscape.  More recently my students have used interviews with farmers in Mexico to understand the role of water as a driver of land cover change.

Our research involves extensive collaboration with other faculty at SDSU and with regional stakeholders.  Find out more about Blue Gold:  Mitigating Water Scarcity and the Watershed Science Institute.
