Abstract
A net includes a bag body, an endless suspension rope, and a top closing rope. The bag body prevents scour of an underwater structure, and is formed into a mesh by a knitted fabric. The endless suspension rope is inserted through the mesh adjacent to an opening portion of the bag body. The top closing rope closes the opening of the bag body, and is inserted through a mesh adjacent to the mesh through which the suspension rope is inserted.
