Abstract

Extension to the oil jetty at the Port of Saldanha will necessitate dredging of the entrance channel. This study was undertaken to determine the turbidity caused by the dredging and also the transport/dispersion of the dredging plumes. Hydrodynamic and water quality modelling were performed in order to determine the environmental impact of the dredging on the nearby mariculture activities, as well as to investigate possible deposition of mud in the Langebaan Lagoon. Turbidity levels due to storms and shipping were compared with the turbidity caused by the dredging. The environmental impact of the plumes is found to be within acceptable ecological limits and only insignificant sediment deposition is predicted in the Langebaan Lagoon.
