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.

Error "child killed: unknown signal"

Dear all, I'm having this problem when trying to run wave gui in Windows: Error "child killed: unknown signal". I have the tags/5.00.00.1234 compiled version. I read that i have to create a SWAN folder manually in other post. This is true?
Please provide me some help.

Thanks,

Dear Eduardo,

Try to do the following, maybe it will help:

1) Create the folder called "swan" inside the delft3d folder (in the folder where you have folders: manuals, source, w32, tutorial,... create manually folder called swan)
2) then copy all the files from wave folder into swan folder (wave folder you can find in w32)
3) try to run examples

Regards,

Mladen

Dear all, I'm also having this problem but with the tags/5.00.02.000000 compiled version
i've tried the swan folder manually but it doesn't work
please help me with this one


thank you very much
