This paper describes the design and development of an experimental sand bypassing and channel maintenance system using jet pumps and fluidizers. The system was developed as a possible alternative and supplement to conventional maintenance dredging. Monitoring of the experiment will address impacts on channel maintenance and nourishment of downdrift beaches. This system is a large scale, and possibly permanent, application of current jet pump and fluidizer technology. This experiment is being conducted in phases such that important components may be tested in an efficient manner. The experience will provide valuable and transferable technology for application to other sites. The U. S. Congress authorized the Corps of Engineers to conduct this experiment at Oceanside Harbor where the Corps of Engineers has channel maintenance responsibility.
