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.

No SMproc output being written

Hi, I have a fresh install of Delft3D and I modified example 01 by adding the line "FlNcdf = #maphisdro#" to my mdf file. This allows me to get netCDF output. However, when looking at the resulting netCDF file I don't see any temperature or salinity variables, or in fact any data that is specified by SMproc in the mdf file (even though this is a string of "Y" characters). And I find that whether I set SMproc to all "N" or all "Y" values makes no difference to my resulting netCDF file. Does anyone know what I'm doing wrong? Is there some other flag in my mdf file that stops SMproc from doing it's thing?

Hi Nicholas,

First of all, you need to include temperature and salinity in the computation (better to turn it on through GUI), then you can use SMproc to set the output options.

Hi Qinghua

Thanks very much for the response. I'm running Delft3D through Linux, is there a text file flag somewhere to turn this on? I don't see one in the mdf file.

Regards

Nick.

Hi Nicholas,

Yes, there is a flag in the mdf-file to switch it on, but that is not enough: you also have to specify initial and boundary conditions and, optionally, additional processes. This is very delicate. You can't do that without the GUI. You can prepare your computation on Windows with the GUI and then copy the input files to Linux to run it.

Regards,

Adri
