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.

Dear all,


In the coupling procces for WAQ, this error appear:

NEFIS message 3006:
 Variable dimension 3 not found for:
 group "CURTIM          ", element "TIMCUR          "

  Exit from Delft3D-Coupling


If you can help me. 

Thanks you very much.

This is rather odd - we cannot find a definitive reason why this should be happening. Can you use the tool "VSI" to inspect the file?

Possible causes we can think of are:

- The output for water quality has not been turned on properly

- The period for which the output for water quality is to be written falls outside the period of the flow calculation
