Numerical Model Analysis of Sedimentation Problems at Lock and Dam 1, Red River Waterway

by Charles D. Little, Jr., US Army Corps of Engineers, Vicksburg, MS, USA,

Document Type: Proceeding Paper

Part of: Hydraulic Engineering


This paper addresses the numerical modeling techniques used to identify the conditions and parameters affecting sediment deposition at Lock and Dam 1. Two-dimensional finite element models were expediently and economically utilized to explore alternative solutions to the problems. Engineering decisions concerning the alternatives were greatly facilitated by the models' adaptability and speed of application. This paper will emphasize the effectiveness of model usage as a tool in the engineering decision making process. Model results and their comparison to prototype responses due to structural additions and modifications recently completed at Lock and Dam 1 will be presented.
