Abstract

Every year, a lot of fluid mud is deposited into the river-fishing port of the Ariake Sea, the function of ports is reduced. Therefore, it is necessary to solve the mechanism which fluid mud deposits into the fishing port. Moreover, it is necessary to create the controlling port depth method, and to be applyed to the target fishing port.<BR>As a result of the investigation about a fluid mud deposition mechanism, fluid mud was conveyed as high-concentration cloudy water from the sea at flood tide, and since having sedimented and deposited in the port was presumed, it was presumed that it was the fluid mud deposition phenomenon by siltation.<BR>Six controlling port depth methods of construction were devised.It was proved by local experiment that there is capability to remove mud about these six methods. At the river-fishing port in the Ariake sea area, the flow figure which judges which should be chosen from six methods was created.
