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.

Post-Processing Alternatives

Youngling Posts: 1 Join Date: 9/24/18 Recent Posts

I am a fairly new user of the DELFT-3D modelling suite, having recently migrated from using TELEMAC for a number of years. While am extremely happy with the overall performance of the modelling suite I feel extremely limited in my ability to interrogate results and perform post-processing calculations using QUICKPLOT. 

While the group that I currently work for has developed a number of alternative scripts for plotting and processing of the results it does not seem like an efficient use of time, compared to the ease and simplicity of using a well developed post-processing package. I am quite familiar with TELEMACs bluekenu package and was hoping that the community may be able to inform me of something similar for DELFT-3D or even something better than QUICKPLOT.

Regards,

Toby

Hi,

QUICKPLOT allows to quickly examine and consequently export the results to the desirable format. You are free to use any other package for the detailed post-processing.

OpenEarth repository contains matlab routines for post-processing Delft3D-results in MATLAB. It is well explained in the webinar 15 on the webinars page

If access to MATLAB is limited, another option might be using Python for post-processing results written in netcdf-format. Personally I haven't tried this, using Python for pre-proccessing only. 

Regards,

Dmitry

Hi Toby,

I agree with Dmitry about the use of Quickplot as first tool of post-processing, as second you could use Muppet.

With Muppet you can do more elaborate plots.
