Abstract

The predictive capability of hydrodynamic and water quality models is illustrated by three applications of the DelftSD modelling suite from WL|Delft Hydraulics along the South African coastline. The first application involves dredging-induced turbidity in Saldanha Bay on the west coast. Modelling of the hydrodynamics and the dispersion and deposition of the turbidity plumes was performed to assess the impact of the plumes on the sensitive ecology in the bay. The second application investigates the feasibility of using seawater for industrial cooling at Saldanha Bay. Since this study involves a thermal discharge into a highly stratified environment, the Del A3 D model was applied in three-dimensional baroclinic mode including air- sea heat fluxes. The mode
