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.

SWAN Error

SWAN Error

I am founding an error performing SWAN simulations and I was not able to solve it.
I have already created new versions of input files, changed folders, changed delft version for an older one that I have here and nothing worked.
The image attached shows more details of the error.

Has anyone seen something like that? Or knows what else it could be?

Thank you very much!

Hi Lucas,

Looking in the source code: it goes wrong when trying to create file "<runid>.swn", were <runid> is the base name of your mdw-file (e.g. if your mdw-file is named "test.mdw", then <runid> is "test"). Can you try to remove that swn-file from the working directory manually? Alternatively: what happens when you start with an empty working directory and copy all the input files in there, excluding the swn-file?
