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.

The coupling of regular and irregular grids

The coupling of regular and irregular grids

Hi Everyone and users of Delft3D,

I have a problem when I try coupling my regular and irregular grids. I attached both and since then I thanks for any help.

I'm user to Delft3D open source, so my question is: is it possible to do this procedure with it or only with Flexible Mesh?

If possible, What I need to do improve my grids?

I appreciate if anyone help me.

Best,
Samuel

Hi Samuel,

To use mixed grids, you can only use the Flexible mesh version.

Hi Qinghua,

Thank you for your return and feedback.

I read all manual RGFGRID and I really sorry for this limitation.

Best regards,
Samuel
