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.

How can I start a simulation from MATLAB, or the DOS prompt?

Dear Support,

I'm trying to automate some delft-3d operations using matlab scripts, but I cannot get a simulation started. For most other executables I'm using the system-command or !-command, plus a textfile for the user input. However, using this on the d3d_filsel.exe doesn't get the simulation started. Is there a way to do this without requiring to click the Start-button from the d3d-menu?

Kind regards

Hi Menno,

You can start a simulation without using the GUI through a bat file. You can see the format of one in your delft3d examples folder.
In order to start a simulation you will have to configure some environmental paths, like the destination of your delft3d executables, inside the file run_flow2d3d.bat. Also, you will have to point out which mdf file you want to run by changing this is your config_d_hydro.xml. Both of these files can be copied from you delft3d examples folder, and adapted to your system.

Taking the opportunity, this is also the method to be used if you want to start a simulation in parallel, using MPI.

Hope this helps you out.
