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.

Good Morning,

I have already received your package for Delft3D 4.03.01 and I attempted to run a specific example : ‘The Friesian Tidal Inlet’ , which is located in the Delft3D_Flow_User_Manual.

It is worth mentioning that the data for this example are from the Delft3D 4.02.01 version. In addition, when I executed the scenario (in GUI/start window) , I received the following message: ‘The d_hydro.exe file does not exist’ . Thus, I utilized the d_hydro.exe file from a previous version (Delft3D 4.02.01 ) , but then I received a new message: ‘ the MDF and DDB files don’t exist’. Can anyone  send to us the d_hydro.exe file for Delft3D 4.03.01 version ?

Please if you can, help me with this problem!

Hi Christoforos,

when you download the GUI package from the Deltares ftp and you do not have the service package, it does not mean that Deltares gives us the Delft 3d system bin files, we have to compile the system souce files.

You should try to compile the Delft 3d and once you have get the bin files, you will copy these files in each of the folders you have in GUI installation folder.
