A sand transfer system that requires no surface impounding area and that can be installed and operated at low cost is proposed The system consists of a hydraulic jet assembly operating from the bottom of a sand crater A jet pump and suction mouth are located at the lowest point of a crater-like depression dredged into the sea floor The crater acts as a gravity-fed sink for sand and other cohesion I ess material, thus serving the dual purpose of a mechanism for collecting sand and a sub-surface impounding area for the accumulation of sand.
