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.

Difficulties with .bcm file

Youngling Posts: 9 Join Date: 5/7/13 Recent Posts

Hello,

I couldn't manage to make my morphological boundary conditions file work properly.

When I start the simulation, I always get the same error: "*** ERROR Unknown boundary "river" in teste.mor". I've already searched the forum and could not found what I am possibly doing wrong.

Could anyone help me?

I've attatched .mor, .bcm and .bnd files.

 

Thank you very much!

Ok, I've managed to run it successfully, but I still have a problem.

I got the same error when trying to run the simulation with the parallel script. Isn't it possible to use this kind of boundary condition with paralell script?

 

Thank you!

Hi

In *.sed file, which keyword did you use in the parameter "SEDTYPE"?

In your *.mdf file, which name or label did you use in the parameter "Namc1"? Is this name, the same that you use in *.bcm file?

Hi Gabriel,

In *.sed file, SEDTYP is "sand". In *.mdf file, Namc1 is "Sedimento", just as written in the *.bcm file.

Hi Lucas,

maybe one of the problems that you have, it is related to the name of the concentration 1; as far as know, the name should start with the word "Sediment", not only "Sedimento". For example, the FLOW manual uses as example the name "Sediment sand".

Please check the 4.5.4 Processes section of the FLOW manual.

 

Regards

 

Gabriel.

Gabriel,

 

I've tried changing the name of the concentration 1, but it is still not working.

The ordinary simulation works either way, but I cannot run it as a MPI parallel based calculation.

I reckon this has something to do with boundaries setup, but I couldn't find it. Or this kind of simulation cannot be performed with parallel techiniques.

 

Thank you very much for the support!

Hi everyone.

I am having the same issue, I can use the bcm files in serial runs but it not work in parallel runs.

I get the same error: "*** ERROR Unknown boundary "myboundaryname" in morfl.mor".

The bcm file is not supported for parallel running?

Did you guys get some advances?

Thanks in advance.

 

Marcelo
