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.

problems in the coupling between flow and wave

Dear all,
I am simulating long-term morphology evolution considering the coupling of flow and waves, but when I run it, the errors atached appear. Would you please tell me the reason?

Best, Zheng

Dear Zheng,

It seems that the executable "deltares_hydro.exe" is called with the wrong argument "file15fddb8". Can you start the calculation by using a batch file? See "https://svn.oss.deltares.nl/repos/delft3d/trunk/examples/03_flow-wave/run_flow2d3d.bat" for an example.

Regards,

Adri

Dear Adri,
The batch file does work. thank you.

best,

Zheng
