Abstract: Abstract: This report describes a project at Los Angeles in 1947. Sandhills (relic dunes) were leveled, and the sand was used to widen the beach against erosion. The project extended from El Segundo to Venice. Water, at high pressure, was shot from nozzles onto the hills. The resulting slurry (sand suspended in water) was sluiced down to a sump or low area. An eductor drew in the slurry by siphon, and discharged it by pipeline to a surge pit. Here, the slurry moved through a surge well to a dredge pump suction. The slurry was then moved by a series of pumps and pipelines to the beach. An amount of about 14 million cubic yards was moved; the price was 22.6 cents per cubic yard (1947). The report describes the process in detail, shows photos and drawings of the equipment and work, and also shows aerial progress photos of the area. Recommendations are presented about using the method in other areas.
