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.

Questions about ERROR NEFIS message 8016

Youngling Posts: 1 Join Date: 6/23/18 Recent Posts

I was running a flow model with two domains. The followings are the error message in the diagnose file:

 

 Creating new trih-Wad.dat
 Creating new trih-Wad.def
 Creating new trim-Wad.dat
 Creating new trim-Wad.def
*** ERROR 
NEFIS message 8016: File 'trim-Wad.def' is not a NEFIS definition file 
*** ERROR Flow exited abnormally 

 

The model was carried out on the version 4.03.01. 

 

Does anyone know the reason for this problem and the corresponding solutions? Thanks a lot!
