| Description: | Technical Report Abstract: A model investigation was conducted to evaluate the performance of a proposed improvement plan and develop modifications, if needed, that would enable the Perry Creek Conduit to safely pass a 16,000-cfs discharge. Model tests revealed that the capacity of the original design flood control channel was only 10,200 cfs and excessive bend losses were occurring. A second improvement plan was designed and tested in the model and found to be satisfactory provided modifications are made to the channel berms and channel invert and a stilling basin is installed at the end of the conduit. Discharge and velocity measurements and water-surface elevations are presented and flow conditions are shown in photographs. |
