Abstract
Abstract This disclosure relates to apparatus for producing and protecting deposits of sedimentary material on a floor of a body of water, the apparatus including a flexible sheet located beneath the surface of the water in at least partially upwardly spaced relationship close to but above the floor, and means for maintaining the flexible sheet so positioned. In its more specific aspects the sheet may be disposed either planar to the floor or arched concavely facing the floor and is preferably formed of mesh-like material having an edge entirely above or in contact with the floor and being supported from beneath and anchored in position.
