| Description: | Technical report Because the existing Kentucky Lock, located on the Tennessee River, is operating at capacity, an additional 1, 200-ft-long by 110-ft -wide lock is projected to be necessary to satisfy future capacity requirements. The new lock features a through-the-sill intake that carries flow to a multiport filling and emptying system. Two alternatives for the lock discharge outlet in the lower lock approach. The other plan had a landside channel that discharge downstream of the lower approach guide wall. The two-dimensional (2D), depth-averaged flow model, HIVEL2D, was used to simulate the unsteady velocities and water-surface elevations in the lower lock approach resulting from lock emptying operations. The HIVEL2D model was chosen for this study because it provides numerically stable solutions for advection-dominated flow containing large gradients in the flow variables. THE HIVEL2D code was modified to allow specification of time-dependent inflow boundary conditions. Simulations of the flow conditions in the lower lock approach for the proposed 1,200-ft lock were performed to evaluate the interlaced lateral and landside channel discharge alternatives. |
