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.

Delft3D-WAVE output error

Youngling Posts: 5 Join Date: 10/21/11 Recent Posts
Greeting, Deltares community!

This is Zhixuan from University of Miami. I am a new user of Delft3D open source and get into some sorts of problem at this moment. Can somebody help me with it? Thanks!

I am trying to set up a coupled flow-wave model for Biscayne Bay (Miami, USA). Before testing coupling, I first tried to run flow and wave, separately. The flow run succeeded.

When I was running the stand-alone wave, the problem seems to me that the model couldn't generate output files.

Here I attached the text

What does this error mean?
ERROR: file 'norm_end' expected to signal a correct SWAN calculation

I also attached mdw file for your convenience.

Thanks very much again~

Hi Zhixuan,

I ran into a similar problem recently. In my case it had to do with the location of the swan-executable (similar to the problem described here). However, your error messages seem to be more related to grid size, see also here.

So, my best guess is that the amount of grid cells is too large. Could you verify that?

Cheers,
Arnold

Hi Zhixuan,

The error is stack overflow. Most probably it is because of the model grid is too much. You can either try 64 bit exes or make your grid size a bit coarser.

Regards,

Qinghua
