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