| dc.description.abstract | This report is intended as an aid to engineers studying alternative solutions to a coastal sand bypassing problem. Using this report, engineers already familiar with coastal processes and centrifugal pumping systems will be able to: (A.) determine the feasibility of a jet pump remedial bypassing system at a given site, (B.) develop initial layouts for such a system, and (C.) perform the system basic hydraulic design. A set of considerations and guidelines relative to feasibility and intial layout are discussed in varying degrees of detail. Two step-by-step hydraulic design procedures are presented, one being an iterative type adaptable to computer solution, the other a graphical approach. Both procedures are keyed to a simple system with one jet pump and one booster pump. Additional considerations are given for systems using multiple jet and/or booster pumps. A companion report to be issued at a later date will describe techniques and equipment for building, operating, and monitoring a jet pump bypassing system. NOTE: This report contained 14 oversize plates that are not included with the scanned report.
