Module 7: Dustpan dredge Copy

[vc_row][vc_column][vc_single_image image=”1199″ img_size=”full” alignment=”center”][vc_column_text]The suspended solids concentration in the vicinity of a dustpan dredge depends on the type of soil being dredged. In the case of free-flowing sand, the turbidity developed for the dustpan dredge can be very small. Significant turbidity is expected at the bottom because of the water jets. In a 1982 analysis carried out for the USACE, preliminary analysis indicated that turbidity was as high for the dustpan dredge as for the cutterhead. Turbidity comparisons between the dustpan dredges and the cutterhead show no clear advantage to using a dustpan dredge over a cutterhead dredge.[/vc_column_text][/vc_column][/vc_row]
