Abstract: A hydraulic analysis of the Whitten Lock filling and emptying system was performed. high-head structure having a design lift in excess of 25 m. Evaluation of the culvert system was considered necessary because the lock's structure has experienced damage over the past years on the roof of the crossover culvert. The purpose of this study was to determine whether or not the hydraulic conditions were significantly different from those anticipated during the design process and whether or not these hydraulic conditions were causing the damage to the crossover roof. A numerical model study of the lock provided peak velocities and pressure differences throughout the filling and emptying system. A one-dimensional model of the entire culvert system including the flow control valves was used in conjunction with a three-dimensional model of the geometrically complex crossover culverts where the damage has occurred. The numerical model results indicated that the hydraulic conditions were not significantly different from those observed in the hydraulic model study conducted during the project's design phase. The current study also investigated the hydraulic consequences of various filling and emptying operations. The Whitten Lock, located on the Tennessee-Tombigbee Waterway in the United States, is a
