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.

Oil dispersion DELWAQ

Hello, I would like to know if it is possible to do the dispersion of oil in the DELWAQ with the source of pollution being on the surface, and I want to add a bioremediation equation next to the model.

Thanks.

Hi,

 

This is not possible in Delwaq. But instead I would like to point to the particle tracking module, which is able to model floating and dispersed oil:

A limitation is that you have to use structured hydrodynamics. The particle tracking module can not work with Flexible Mesh hydrodynamics yet.

Hi Michelle,

 

thanks for your reply!

It helped a lot!! And I saw that I can do the coupling with my hydro.

 

Thank you!
