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.

Make ASCII files from map file

Hello everyone.

I have completed Delft3D-FLOW experiments in my research site.
Now I am the results being expressed.
I have to make ascii files from result map file use GPP tool.
My computer does not works Quikplot.

Can I extract ascii files from map file, automation?
Please let me know how to extract.

Hi Jaegab,

I am not sure if I understand what you exactly want, but as far as I know the easiest way to get Delft3D results is using either Quickplot or Matlab. You say that Quickplot does not work on your computer, do you have any idea why? If you have Matlab, you can sign up for Open Earth Tools ( and download a large amount of tools that can help you to read Delft3D results.

Hope this helps.

Dear Jaegab,

You may want to look into the tool called Datsel. You can find it in the Delft3D GUI. The Delft3D-WAVE manual has a little description on how to use it (not sure why it's in the Delft3D-WAVE manual, because you can also use it to extract data from Delft3D-FLOW ouput).
