20. ABSTRACT (Continue on reverse aide if neceaaary and Identify by block number) 



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
