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.

Running wave.exe from command prompt

Running wave.exe from command prompt

I am trying to start a wave-computation from the command prompt using a line like the following:

>wave.exe modelname.mdw 0

The zero at the end of the command line is supposed to control the mode of the wave-computation, 1 for online computation with FLOW, and zero for stand-alone. However, the run initiated with the command shown here still stops to wait for a FLOW-computation, even though the flow-computation has already run, and the com- and trim-files are already generated.

Is the command correct? or is there some other reason why the wave-computation won't start?

Hi Menno,

If you want to run the wave model without flow online, the command is correct, but you have to specify the time points in mdw file for the model to run.

If the wave model is running with flow online, it is automitcally take the communication time step (time points) to run the wave.
