Welcome to the home page of the Satellite Hydrology Research Group at The Ohio State University. This group uses satellite-based measurements to study rivers, lakes, wetlands, and floodplains. Led by Dr. Douglas Alsdorf, group members primarily use radar to measure water elevation, from the Amazon River to the Ohio and Muskingum Rivers. This group is helping define an upcoming satellite, Surface Water & Ocean Topography (SWOT).
SWOT will track freshwater resources, as well as measuring ocean currents. SWOT is a joint effort between NASA, the Jet Propulsion Laboratory and the French space agency, CNES. Rivers are fundamentally two-dimensional in their structure and function. This is evident in the Amazon, where the floodplain width is measured in kilometers. Sensitive to climatic changes, arctic lakes pose another hydrologic measurement challenge. SWOT measurements will enable new understanding of these complex systems.
