Assessment of Potential Impacts of Dredging Operations Due to Sediment Resuspension.

Abstract

This technical note summarizes the known biological responses of estuarine and coastal fish and shellfish to suspended sediments and relates these findings to suspended-sediment conditions associated with dredging projects. An objective approach toward evaluation of sediment resuspension impacts is proposed that requires full consideration of (a) the existing state of knowledge concerning the effects of suspended sediments on fish and shellfish, including recognition of the gaps therein, and (b) concentration-exposure duration combinations likely to be encountered by organisms in the vicinity of dredging operations. This note focuses upon the exposure of organisms to sediments in the water column. Effects of deposited sediments will be treated separately.
