Abstract:
In order to prevent further pollution of the ocean environment in the Inland Sea of Japan, the Ministry of Transport conducted a bottom sediment improvement test by sand overlaying in Hiroshima Bay. Prior to execution of this test, a test to overlay the bottom sediment with sand of a thin layer was conducted by using a barge unloader sand spreader. As a result, the following facts were discovered It is possible to evenly spread a sand cover over bottom sediment to a specified thickness with relative ease. The disturbance to bottom sediment is minor because the sand is gently spread. Water pollution caused by the resuspension of bottom sediment or overlying sand is minor. It was confirmed, therefore, that the sand spreader process is feasible for practical use as a sand overlaying process for bottom sediment improvement.
