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.

Source code for ddcouple

Hi,

could anyone send me the source Code of ddcouple? I cannot use the published ddcouple for  Linux, because of differences between Compilers. After running the ddcouple in console and Input the ddb file, the Compiler cannot recognize the published ddcouple.

This is the latest version of ddcouple. It contains a fix for the following issue:

Issue: DELFT3D-35908
DDCOUPLE removed an external boundary when it accidentally overlaps with an internal MPI domain boundary. Only replace a boundary with a segment number when there is an actual segment on the other side of the domain boundary, other wise the boundary remains. For the final lga, we need to scan an extra row/column in the grid to see if there were any boundaries left there.

 

It also contains a script to set the LD_LIBRARY_PATH to the directory where the compiler so's reside. You have to change the path mentioned to where you placed the executable yourself.

 

I hope the problem isn't caused by the number of domains you have. There shouldn't be any hard coded limits, but it is an old program so I'm not sure.

Hi Michel, thanks for your answer. It also does not work. I used the attached exe file and it works successfully.

Glad you could work with the windows version :-)
