September 2009 Flooding Sweetwater Creek at Interstate 20, Lithia Springs, Georgia
Detailed Description
This is the Interstate 20 bridge over Sweetwater Creek. The USGS hydrographer is hand-pulling an Acoustic Doppler Current Profiler across the channel. The instrument, on the small orange catamaran in the picture, determines the depth of the channel and the discharge of the water and transmits data to a laptop in the van in the far left of the photo. The channel was up to 30 feet deep in places and discharge was around 25,000 cubic feet per second.
