This article is an extract from the award-winning paper of the same title presented at the 7th World Dredging Conference held in July 1976 in San Francisco, U.S.A. From the viewpoint of the protection of the environment and marine resources, turbidity of the sea surface due to muddy water overflowed from a hopper dredger has become a social problem. To cope with this problem, the authors et al. conducted a series of experiments on model and actual dredgers in cooperation with Tokushu- Shunsetsu Co., Ltd., and developed a simple and economical new overflow system which effectively prevents turbidity of the sea surface. This new Anti-Turbidity Overflow System has been applied to two existing trailing hopper dredgers in Japan, enabling them to operate without adversely affecting the environment in such applications as for cultivation farms of marine products such as sea laver, pearl, etc.
