How does a CSE remove sediments?
The CSE consists of two basic components. They include a mechanical dredge (bucket) and a housing or enclosure. The mechanical dredge (bucket) is contained within the rectangular-shaped housing that is open on the bottom, where a single-hinged door is used to open or close the housing bottom. During the excavation process, the CSE is lowered to the bottom of the waterway where the bucket extracts from the open bottom to collect sediment, similar to that a conventional dredging operation. After the sediment is collected, the bucket retracts into the housing and the single-hinged door closes as the CSE with its sediment load is raised to the surface.
