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.

Plots not showing correctly from D Water Quality User Manual tutorial

Hello,

I've followed through the tutorial from chapter 7 of the D Water Quality User Manual. When generating the Plots from the session file "tut_fti_waq.ssn", the three plots "Map Concentration E. Coli, 2x2", "Inorganic matter IM1, 2x1" and "WAQ parameters, 2x2" show blank axes and no results (see attached image).

The other two plots "Time-series E. Coli, 2x1" and "balances, 2x2" show up correctly. I'm using "delft3d_ohmw_4.01.01.rc.03" compiled on Windows.

Any idea why this might be occurring? Would appreciate any help with this.

Hi Matthew,

Can you visualize the map file using Quickplot instead?

If not, check your lst file for any warnings or errors.

Hi Christophe,

Thanks for your reply! I can visualise the map files using Quickplot, so that's a good enough workaround for now. Is it possible to view the SSN files associated with the tutorial in Quickplot?

Many thanks,
Matthew

The ssn file is specific to GPP and is a way to save predefined plots.
It does not contain any simulation results.

QUICKPLOT does not support ssn files but allows you to records macro's.

Hi Christophe,

I think that's resolved all the issues! Many thanks for your help.

Cheers,
