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. 
On this discussion page you can post questions, research discussions or just share your experience about modelling coastal and/or estuarine systems with Delft3D FM.

Delwaq problem by generating proc_def.def and proc_def.dat

Dear Delwaq developers,

I am trying to follow the instructions on page 30 of the Open Processes Liberary (OPL) manual. I did it for both Linux as well as Windows, but none of them produced the proc_def.def and proc_def.dat after compiling (the compiled results are attached). I think this was not mentioned in manualĀ or Delwaq has a problem by producing the proc_def files. Could anyone tell me what should I do after build/compilingĀ ?

The definition of the processes you add via the Open PLCT GUI to the set is automatically stored in the processes library files you selected. If you open those, then you should be able to see the new processes. Note that this may be the processes library files that come with the installation.

By the way: I have added the makefiles needed to make the waqpb programs on Linux - these were missing (we simply never created them for these tools). After an update of the source code you should be able to build them as part of the general build process.
