Study and Evaluation of Remedial Sand Bypassing Procedures.
Abstract
The purpose of this program was to investigate and develop a practical method for the management of sand influenced by littoral transport. The work covered laboratory research, field investigations, and tests. Initially, laboratory investigations of jet pumps, crater-sinks, and fluidization were conducted using specially designed apparatus. During the laboratory investigations a new principle of fluidization was developed. This new form of fluidization is called 'duct-flow' fluidization. Duct-flow, when used in conjunction with the crater-sink principle, greatly expands the scope of sand management systems. Field tests of craters dredged on the ocean floor showed that wave action causes the crater to elongate in a direction parallel to the wave crests. The result is an eliptical shaped crater. Field and laboratory tests of duct-flow show that the bulk volume flow rate of sand from the fluidizer is proportional to the drive-water flow rate. The dimensions of a protype duct-flow system appear to be almost unlimited.
