The data collection for the concrete-walled channel downstream from the Brandon Road Lock and Dam near Joliet, Illinois occurred in May 2014 Five pounds per square inch (lb/in2) was used as a threshold water pressure value for this study as this value incorporates fish behavior and structural integrity considerations. The Brandon Road study evaluated the performance of two different water gun configurations within the concrete-walled channel downstream from the lock with depths ranging from 12-15 feet. Data from a single 80 cubic inch (in³) water gun produced a roughly cylindrical 5 lb/in2 pressure field 20 feet in radius, oriented vertically, with the radius decreasing to less than 15 feet at the surface. A combination...

The study at Lemont replicated and expanded upon seismic data collected at that location in 2011 as well as evaluated the pressure field created in the water by the water gun. The replicate data were collected with the water gun placements and input pressure identical to the 2011 study, but added static underwater pressure monitoring. Two 80-in³ water guns were suspended below a platform at depths of 4 and 14 feet. Pressure values were lower when only the gun suspended at 4 feet was fired as compared to firing the single gun at 14 feet and both guns simultaneously, with the latter two producing similar pressures. Data were collected to assess the pressure field produced by two 80-in³ water guns suspended at a depth...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
