Geophone Data from the Chicago Sanitary and Ship canal near Lemont, Illinois (2014).

Resource Abstract:
description: 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-in 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-in water guns suspended at a depth of 14 feet, but separated by 80 feet. A 5 lb/in threshold value, based on limitations set by the Army Corp of Engineers (USACE), was monitored throughout the experiment. Extent of the 5 lb/in threshold value varied significantly with gun input air pressure. The pressure field generated with gun input air pressure at 2,000 lb/in exceeded the threshold value at greater than 95% of locations measured more than 30 feet from the water guns, whereas data at 1,000 lb/in did not reach the threshold value anywhere outside of a 30 foot radius from the water guns. Velocity and acceleration data were collected simultaneously with the underwater pressure data to understand the response of the wall to the water gun firings. Maximum values for velocity and acceleration were 0.304 in/s and 0.015 ft/s, respectively.; abstract: 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.
