PROBLEM TO BE SOLVED: To obtain an environmentally-friendly, permanent and easy method for accelerating flow-down of sediment accumulated in a river and the like. SOLUTION: A structure, which is made of a material such as a stone, a rock, concrete, iron, other metals and wood, is installed along a flow direction in a stream of water, so as to accelerate the flow-down of the sediment accumulated in an upstream place or that place. The structure is formed in a shape like a fence, a retaining wall, a colonnade composed of a pile and a column, or a bedrock, and fixed to the bottom of the water so as not to be deformed and displaced by the stream of the water. This method, which artificially reproduces a naturally applied action as-is, exerts its effect on any place where the stream of the water and the sediment of soil, sand, the stone, etc. exist.
