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.

Delft Flow-WAQ coupling error

need help!!!
I am trying to couple flow and waq modules.

The flow model ran successfully and generated the com- file for the coupling. But, When I try to run the coupling program, I get the following error message. Can anyone suggest what might be wrong in my flow or coupling set up? Thanks

are you using the correct input file ??
for input files of => v2.4 use header:

From your message I could only suggest what the message already says: are you using the correct input file ??

Besides that I could strongly advise you to use the online couling program in your flow runs. Switch on Export WAQ input, and use the edit WAQ input button to go to the next screen, and make the correct settings.
