TURBIDITY CAUSED BY DREDGING

Open publisher page 16 citations

Abstract

This paper discusses the turbidity due to two dredging methods. One is turbidity caused by pump dredger, and the other is grab dredger, using a closed type grab bucket and a conventional one. These experiments were conducted out in the field. In the former case, the paper shows the relationships between turbidity and dredging conditions. Turbidity is measured around the cutter head and at the several points farther than 20 m from the central point of dredging. In the latter case, the experiment concentrates on the comparison between the properties of turbidity caused by the closed type grab bucket, which has covers attached to rods and shells.
