Remote Sensing Hydrology Research Group

The Remote Sensing Hydrology Research Group uses hydrogeophysical tools, including satellite, airborne and ground-based geophysical methods, to address water resource problems. The group is led by Ryan Smith, an Assistant Professor at Missouri University of Science and Technology's Geological Engineering program.

By combining geophysical datasets--primarily interferometric synthetic aperture radar (InSAR) and electromagnetic (EM) data--with hydrologic time series, we are able to quantify changes in groundwater storage and quality. A sample of some of the research we do is shown in the figure below.
