Method overlap riverbed folded predominantly fine-grained material, comprising a preliminary restriction channel transversely disposed webs from local materials to form a closure channel, the dimensions of which are determined by the magnitude of a non-blurry speed of the material, and closing the closure channel incoherent material, characterized in that in the zone of the future closure channel the bottom of the riverbed lined grid, which is set transversely to the channel spatial structure penetrating from the inside, which is closed Setko After which mesh in the area covered by the closure channel coarse material, size of which is determined by the mesh size, and spatial structure are fixed in the ends of the respective end of the webs ends of local material, which is covered by the coarse material and spatial structure so as filled incoherent material.
