Red River Waterway, Lock and Dam Number 3. Report 5. Sedimentation in Lock Approaches. TABS-2 Numerical Model Investigation

Abstract : A two-dimensional numerical model, TABS-2, was used to predict fine sediment deposition in the lock approach channels upstream and downstream from proposed Lock and Dam No. 4 on the Red River Waterway, Louisiana. The numerical model was used to evaluate alternative designs. Fine sediment deposition with the proposed design at Lock and Dam No. 4 was compared to fine sediment deposition at existing locks and dams downstream.
