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.

Tsunami Simulation with Delft Dashboard

Dear Sir:

I tried to simulate the tsumina propagation iwith Delft Dashboard (64-bits version). For somehow, when I move to "OUTPUT" in Delft Menu, the dos window always shows the following error message and the compiled batch file can't be run appropriately. Please advice how to fix the problem.

Error using feval
Indefined function 'ddb_updateOutputTimes' for input arguments of type'double'.

Error in gui_addElements>finishCallback (line 783)

Error in gui_addElements>edit_Callback (line 466)

Error while vealuating uicontrol Callback.

Thanks very much

Dear Leon,

Are you running Dashboard from Matlab or as a standalone executable? I checked for the 64 bits executable, but cannot reproduce the error. If you're running it from Matlab, it seems that the file ddb_updateOutputTimes is missing. It should be in the folder DelftDashBoard\main\operations.

Kind regards,
