CONSTITUTION: On the curved portion 2 of river 1, a scouring preventer 11 is projectionally set with a spacing from the outside wall 7 of the river 1 on the outside riverbed 6a. The preventer 11 consists of plural vanes 12 and fitters 13 to fit the vanes 12 to the riverbed 6, and at least outer surfaces 12a of the vanes 12 are composed of an elastic material. When stone and sand flow down on the curved river 1, boulder 16 and sand and gravel are isolated from the outside wall 7 and their flow direction is changed to the upside by collision with the vanes 12, and thereby souring by sub-flow 4. The durability of the scouring preventer is high because of excellent resilience of the vanes 12.
