Red River Waterway John H. Overton Lock and Dam. 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 the John H. Overton Lock and Dam on the Red River Waterway, Louisiana. The numerical model was used to evaluate the effects of various design changes on fine sediment deposition. These included changing the length and height of divider dikes, the number of openings on the ported guard wall, the invert elevation in the lock approach channel, and the location of spur dikes. Keywords: Locks waterways; Two-dimensional computer programs; Channels waterways sedimentation; River dikes/dams.
