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.

Delft3d wave-flow coupling issue

Dear Deltares,

I ran into a problem when tried to set up wave-flow coupling in Delft3d. I think flow setup is OK but there was something wrong with the wave setup that waves cannot be calculated. I just couldn't find the problem myself.

I copied the message for your reference. Thanks very much! Zhixuan

Hi zhixuan,

Can you provide more information? This is not enough to judge.

Hi Feng,

Could you find a solution for your problem, it seems that I am also having the same.

Cheers,

HI, Dissa!

My problem was with the communication file. Please double check the setting related to wave-flow coupling.

Thanks, Qinghua!

I found the problem myself. The communication file did not set up correctly.
