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. 
On this discussion page you can post questions, research discussions or just share your experience about modelling coastal and/or estuarine systems with Delft3D FM.

Good day all,

Has anyone tried with an UNSTRUCTURED grid for Delft3D?

Hi Dissa,

I assume you are referring to the development of D-Flow Flexible Mesh? More and more functionalities are currently being added to the DFM-code, but it is still under development. On this section of the forum some updates are posted regularly, and hopefull there will be some news soon about the release date.

So if you want to stay updated, keep an eye on the forum!

I have tried. For some reason, RGFGRID crashing while combining rectilinear mesh with triangular mesh.

I have exactly followed the procedure explained through Screen shots.

Dear users, please share your experience with unstructured mesh (D-flow flexible mesh) generation with RGFGRID.

Hi Chiru,

The current screencast uses a development version of RGFGRID, and is merely to show future functionality, flexibility and RGFGRID workflow.
A new version of RGFGRID will be released soon, which allows you to use this functionality as well.
