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.

Set up Tide model in Delft Dashboard

I used the DELFT-Dashboard to set up a tidal model. Every time, when I clicked "Make Boundary Condition" and then save the file "XXX.bca", an error message is shown as in the attached file. what is the problem with the DELFT-Dashboard?

Thanks a lot in advance,

Dear Leon,

From here it is hard to judge what goes wrong exactly, but it seems that DelftDashboard couldn't acces the netCDF file with tidal data, for example because the server was down at the time of your request or because you don't have permissions (from your ICT dept) to access these databases. Personally, I haven't encountered this error before. If you continue to run into problems, you can send me zipped copy of your model setup and I'll try whether I can fix the problem.

Kind regards,
