When dredging, sediments are loosened, stirred, and dispersed into the water column. These sediments then resettle overtop the freshly dredged area and downstream when a current is present. The Cable Arm Environmental clamshell features an open center and venting system to allow the bucket to descend without water pressure buildup beneath it. The bucket is designed with overlapping side plates to prevent sediment from pushing out the sides, and to seal in the material. Rubber flaps and the material's low center of mass also help seal and enclose the sediment to prevent washout during ascension. |
