intro story Coast / Estuary

Coast / Estuary

Coastal systems are among the most dynamic physical systems on earth and are subject to a large variety of forces. The morphodynamic changes occurring to coastlines worldwide are of great interest and importance. These changes occur as a result of the erosion of sediments, its subsequent transport as bed load or suspended load, and eventual deposition. 
Estuaries are partly enclosed water bodies that have an open connection to the coast. Estuaries generally have one or more branching channels, intertidal mudflats and/or salt marshes. Intertidal areas are of high ecological importance and trap sediments (sands, silts, clays and organic matter).
Within the Delft3D modelling package a large variation of coastal and estuarine physical and chemical processes can be simulated. These include waves, tidal propagation, wind- or wave-induced water level setup, flow induced by salinity or temperature gradients, sand and mud transport, water quality and changing bathymetry (morphology). Delft3D can also be used operationally e.g. storm, surge and algal bloom forecasting.

Dredging of contaminated sand

Dredging of contaminated sand

Hello everyone

I’m trying to simulate the spread of contaminated sediment while it is being dredged. Sediment under the seabed has already been polluted by a steel factory and I have to model the advection and diffusion of this pollution when the sediment is dredged. Assume that bed is initially vertically homogeneous.

Does anybody have an idea how should I treat this situation? How can I define the contaminated sediment and which modules must be used for the simulation?

 Any advice is greatly appreciated.
