Seabrook Lock Complex, Lake Pontchartrain, Louisiana; Design for Wave Protection at a Temporary Entrance during Various Phases of Lock Construction. Hydraulic Model Investigation.

A 136-scale undistorted hydraulic model reproducing the site of the proposed Seabrook Lock Complex. The Inner Harbor Navigation Canal at its junction with Lake Pontchartrain, portions of the New Orleans Lakefront Airport, the stepped seawall adjacent to Lakeshore Drive, and sufficient offshore area in Lake Pontchartrain to permit generation of the required test waves was used to investigate the design of proposed breakwaters with respect to wave action. The proposed breakwater plans involved the placement of sheet-pile and floating structures arranged to provide wave protection to a temporary entrance during various phases of lock construction. An 80 -ft-long wave generator and an Automated Data Acquistion and Control System ADACS were utilized in model operation.
