The Corps of Engineers opened Lock and Dam No. 1 on the Red River Waterway in 1984. During the first runoff season, excessive quantities of fine sediment deposited in both the upstream and downstream lock approach channels. Two-dimensional numerical model studies using the TABS-2 computer programs were conducted to determine remedial measures to significantly reduce hydraulic dredging, especially in the vicinity of the lock miter gates. This paper addresses the studies and evaluates the effectiveness of the construction measures.
