Abstract : This paper describes the result of a field dredging test carried out as part of a study of a method of effective removal and disposal of bottom sediments in a vast closed water area such as Tokyo Bay. We manufactured a new type drag head that can dredge soft mud, dredging thinly and widely, in high density. We equipped a trailing hopper suction dredge (hopper capacity of 4000 cu m) with thisnew drag head and field tested off China in Tokyo Bay. Good results were obtained.
