FIELD: hydraulic engineering, particularly for securing coasts.
SUBSTANCE: structure includes mesh grids wound off rolls and laid on coast with directing longitudinal sides thereof across stream and with overlapping mesh grid edges. Mesh grids are secured by anchors driven into coast at right angles to coast surface. Mesh grids are laid on pre-arranged base formed of inverse filter made of gravel or rushed stone and placed on coast surface. Mesh grids are connected one to another by connection wires and create entire mat with base deepened in ground. Attached to mat are trees or bushes connected to mesh grids by wires.
EFFECT: increased efficiency and reliability of coasts protection against erosion and increased service life of flexible structure.
