[Video from the Army Corps of Engineers’ “Old River Hydraulic Sediment Response Model Study”, in which a physical model of Old River Control was used to test the distribution of sediment deposition under various flow conditions in the Low Sill and Auxiliary Structures. The testing was prompted by the observation of problematic deposition in the inflow and outflow channels of both of those structures since the construction of the Hydropower station. This particular video shows deposition at the Auxiliary Structure’s inflow channel; additional landscape experiments can be seen at the Applied River Engineering Center’s website.]
