Abstract : Tests were conducted on a 1:40-scale model of Big Creek to investigate the hydraulic performance of a proposed floodway channel and a section of modified channel. The model reproduced the entire proposed floodway channel, a portion of the existing Big Creek main channel, and a section of modified channel downstream from the existing channel. Distribution of flow between the existing channel and the floodway channel was found to be slightly different than anticipated, but this difference was so small that it had no significant effect on flow conditions in either channel. A concrete transition between the downstream end of a three-barrel conduit and the modified channel caused flow to concentrate in the channel which resulted in movement of the riprap immediately downstream from the transition and along the left bank. The concrete transition was removed, and the area was shaped with riprap. This resulted in satisfactory flow conditions in the modified channel. (Author)
