Remote Sensing for Watershed Sciences

Remote sensing is a useful tool for mapping and monitoring processes and features important for watershed analysis. We use a combination of satellite imagery and unmanned aerial vehicles (UAVs) to map land cover, stream channels, topography and evapotranspiration for use in watershed and hydrological models.

Land Use Change, Crop water use and Water Resources

Water scarcity both drives and is impacted by land cover change. This series of projects aims to map crop water use and land cover change in irrigated agricultural regions, including applications in India, Southern Africa, California and on the US-Mexico border, and to document the major drivers of those changes through mixed methods approaches that integrate remote sensing for automated mapping of crop water use (evapotranspiration) and land cover, quantitative survey data, and qualitative interviews. Applications in California and on the US-Mexico border are supported in part through the NOAA CREST program Leave geography site. Students involved: Yelena Granovskaya, Joel Kramer, Gabriela Morales, Alex Messina.
