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.

Stream file not found in online coupling

Hi all
I used to use an older version of Delft 3D with no problems but recently i have updated the source to 5656 and the latest version of GUI as well.
I have simulated a bunch of online couplings with no problem and the results was pretty good as well...
Now as my aim is to simulate sediment transport i have added the required files and after starting the simulation i see the flow exited abnormally.
Checking the tri-diag it shows the error below:

All the examples have ran compeletly after compiling the code and i just get a few warnings which wasn't major!
Does anyone know what should i do about the stream file?
Should i check the code again?
Cheers
Afshan

Hello everyone
I can see that the problem is related to the installing tcl on my system and it seems that i may not be able to continue my simulation into getting results for online morphology...
The Activetcl is not supported in my country and i think i have to work with older versions to get the results since back then i didnt need the software....
