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.

32 bit or 64?
Answer (Unmark)

Dear Deltares
Thanks for your support, I have a question, I have been requested for GUI and you send me the 64 bit version of Delft3D GUI Delft3D 4.03.01, but my system OS is 32 bit. I would be appropriate if you inform me that can I have access the 32 bit version of Delft3D GUI Delft3D 4.03.01? Moreover, I looked at the FAQ page and I understand that your formal version of Delft 3D is 32 bit and you say “Compiling and running a 64-bit version is possible but testing is still in progress”
Best regards

Hi Meysam Bali,

64bit is the default now. The last 32bit version of the Delft3D GUI, 4.00.02, is available upon request.

Thanks for reporting that the text in the FAQ is wrong; it is corrected now.
