摘要： PROBLEM TO BE SOLVED: To provide a means that can acquire a distribution situation after charging a bottom sediment improving agent into a closed water area or the like and supply bottom sediment improving components more surely into the object water area.SOLUTION: A bottom sediment improving structure A having a solid agent 1 containing bottom sediment improving components 12, and containing magnetic bodies M as components is charged into a closed or semiclosed water area. Then the bottom sediment improving structure A is retained in bottom mud where the solid agent 1 dissolves to improve a bottom sediment therearound. At the same time, since the bottom sediment improving structure A includes the magnetic bodies M, the distribution situation can be acquired by a magnetic searching means or the like after charging the bottom sediment improving structure A. Bottom sediment improvement in the object water area can thereby be uniformly and surely made even when the object water area is wide and the transparency of the water area is low.
