Περίληψη

Grain size trend analysis is applied to the determination of sediment transport pathways over the Kwinte Bank southern North Sea which had been subjected to intensive dredging within the context of the environmental impact of dredging activities On the basis of the results of grain size trend analysis focused mainly upon the transportation of the non biogenic sedimentary material (<2 mm) it appears that (1) there is a main sediment pathway over the western (bank crest) and central (dredged area) part of the bank directed toward the NE whilst a secondary pathway is established over its eastern gently sloping flank h wing a SE direction Further the present analysis shows that the area of the central (dredged) depression acts more as a by passing zone rather than as a depo-centre for the non biogenic sediments Comparison undertaken with the results of an earlier investigation for a non-dredged area at the northern end of the same bank reveals that the depression due to dredging modifies significantly the sediment transport pathways this may be attributed to a change in the seabed morphology which in turn modifies the near bed hydrodynamics (related to tide and/or storm events)
