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.

Floating Structures in Delft3D

Hey All,

I was wondering if it is possible to model a floating structure, say a floating breakwater, to analyze wave transmission coefficients using Delft3D wave. I need to find out how well a breakwater would perform in a given area and the breakwater will be sized based on the calculated transmission coefficients. Has anybody done something similar before?

I read the section on floating structures in the manual and could not find an answer.

Rgds,

Ajay

RE: Floating Structures in Delft3D

Hi Ajay,

As far as I know it is not possible to carry out such a study with Delft3D. You can include a floating structure in the flow module, however, as stated in Appendix B.3.6. all wave related processes are turned off, so I guess it is not useful for your study...

Cheers,
Arnold
