Abstract : The U.S. Army Engineer District, St. Paul (NCS), and the Soil Conservation Service (SCS) have planned a combined flood-control project for Rochester, Minnesota, involving the construction of upland reserviors, channel modifications, levees, and other structural features as well as floodplain regulation changes to reduce the flooding hazard. The channel modifications include combinations of general channel widening, increasing channel slope by channel straightening, and decreasing channel roughness by clearing and grubbing that occur with channel enlargement. NCS asked the U.S. Army Engineer Waterways Experiment Station (WES) to determine the impacts of proposed channel modification and impoundments on the sediment transport characteristics of the South Fork Zumbro River and two of its tributaries, Cascade and Bear Creeks.
