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.

Hi, I am new in Delft3d.  Can we couple Swash with Delft-3d flow instead of SWAN? Regards,

Hi Nora,
I was wondering why would you need this kind of coupling? SWASH is capable to simulate most of the processes, which Delft3D-FLOW describes, in a non-hydrostatic mode. So there is no need in online coupling between these models.
If you'd like to make some nesting to obtain boundary conditions for the detailed SWASH domain from the Delft3D-FLOW model, I think this is possible but requires some work to do. I suggest you to start with this section in D3D-FLOW user manual and examine the possible types of boundary conditions in SWASH.
Regards,
Dmitry
