Abstract:

Between August 1983 and August 1984, model and prototype tests were run on the spillway of the Glen Canyon Dam. The tests were used to design and evaluate the performance of the aeration slots constructed in the 41-ft diameter tunnel spillways. Several parameters, including: air velocities in the aeration slot and pressures (static and dynamic) throughout the tunnels' vertical bend section were measured for comparison of model and prototype data. A computer-based data acquisition system was used for both the model and prototype tests.
