Abstract:

In response to rising dredging costs, the Navy has developed a number of concepts for sedimentation control systems, which serve as alternatives to conventional dredging. One concept, the scour jet array, prevents sedimentation through the scouring action of submerged near-bottom water jets. This report presents the design of a scour jet array test bed which will be used to verify proposed scour equations and to evaluate new design technology. The 66-jet array covers a total fo 366 m 1,200 ft of quay wall and is capable of scouring to distances of 30 m 98 ft from the wall. The jet array is powered by a 0.379 cu msec 6,000 gpm, 336 kW 450 hp vertical turbine pump. An automatic control system is included that utilizes pneumatically actuated valves and a microprocessor controller. The microprocessor also serves as an instrumentation data logger, facilitating testing as well as routine operational checking. Author
