Abstract: Cannelton Locks and Dam, proposed for construction on the Ohio River, will replace existing Locks and Dams 43-45. The project comprises two locks with clear chamber dimensions of 110 by 600 ft and 110 by 1200 ft and a 1365-ft-long, gated, nonnavigable dam, with provisions for powerhouse facilities at the left end of the dam. An undistorted, 1:120- scale model reproducing 8 miles of the Ohio River, the locks and dam structures, the hydropower plant, and other structures that affect flow conditions was used for the investigation. The principal results of this investigation indicate the following : (A.) Velocities along the lock side of the channel will tend to be high. Ports will be required in the upper guard wall to eliminate or reduce the crosscurrents that develop near the end of the wall. Velocities in the lock approach can be reduced by placing submerged dikes along the right bank. (B.) Ice and debris will tend to move along the lock side of the river, with the concentration on that side increasing as the river discharge increases. With ports in the upper guard wall, most of the debris and ice moving along the right bank will tend to be trapped in the lock approach between the upper guard wall and right bank. (C.) Orientation of the powerhouse and tailrace can affect navigation conditions in the lower lock approach. Spoil placed on the overbank upstream of the powerhouse intake channel can affect flow through the dam gates adjacent to the powerhouse and increase river stages during high flows. (D.) Satisfactory navigation conditions can be developed over the overflow section between the spillway and powerhouse with some excavation along the left overbank upstream of the powerhouse intake channel. (E.) The head on the lower lock gate at the end of lock emptying can be as much as 0.6 ft, depending on velocities along the lock side of the channel. The head can be reduced to nearly zero by placing a vertical wall along the upstream side of the stilling basin.
