open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear all,

Sorry, I am getting back to this post as I did not know where to post my new queries. I am progressing step by step in using the TELEMAC modelling platform. However, as part of my phD thesis, I would like to modify a few source codes in order to simulate the processes with regard to my research and possibly develop later my own subroutine and incorporate it into the TELEMAC system. Therefore, I have two questions: Where could I find documentation explaining the contents, structures and calling of the source codes? and do I need to subscribe to anything in order to be allowed to modify and/or create codes to be run within the TELEMAC system ?

Thank you for your kind reply.

Jean-Philippe

Dear Jean-Philippe

Regarding your first question, you will find the code documentation link on the front page, under develop>source code information

Regarding your second question, as the code is open source, you can do any modification to the code you would like for your own use.

However if you would like your developement to be eventually integrated into the official TELEMAC-MASCARET release, it will need to go through the official validation procedure. In this case we can also create a developpment branch for you. In the latter case, please send an email to the scientific board at ot-scientific at opentelemac.org explaining amongst others: the developement you would like to carry out, what benefit it will bring and the development plan.

Looking forward to hear from you.

Dear all,

Thank you for the clarity. I will let you know in case we decide to integrate our work within the Telemac system.

Kind regards,

Jean-Philippe

Dear all,

Following my previous posts, I realised that it would be interesting to let you know about my PhD research. My aim is to model the eco-morphodynamics of tidal marshes, which implies a coupling between the morphodynamics and vegetation dynamics in order to account for the feedbacks and interactions between vegetation, flow and geomorphology. Surely, the vegetation model will have to be built from scratch paper, however I was wondering whether the morphodynamic module (i.e., SISYPHE) of the TELEMAC system could answer in a robust way the morphodynamics of this kind of tidal systems (which are characterised mainly by transport of cohesive sediments and with the need of implementing processes such as bank erosion of tidal creeks for instance). In this respect, I would like to know if the TELEMAC system has ever been tested on this field of research. I mean, is there any validation case on this type of study?

I actually downloaded the article entitled: "Morphodynamic modeling using the Telemac finite-element system" written by Villaret et al., (2011) but even though I did not read it yet, it concerns non cohesive sediments.

Thank you for your kind reply.

Hello,

We have also a PhD here on bank erosion, which is coming to an end, but it is with non cohesive sediment.

For the interactions between flow and vegetation, please note that there is a friction law in telemac-2D that accounts for vegetation (i.e. that can bend when the current increases), this has been developed at BAW.

With best regards,

Jean-Michel Hervouet

Dear Mr. Hervouet,

Thank you for your reply. Concerning this friction law that accounts for the influence of the vegetation on the flow, are you in fact mentioning about this Lidner's law as I saw in the TELEMAC2D user manual ? Is there any publication on that concept ? I couldn't find any one on internet.

Has there been any official publication also on this bank eorosion study as well ?

Kind regards,

Jean-Philippe

Hello,

The Lindner law has been programmed by BAW Karlsruhe, maybe our german colleagues can provide references...

The PhD on bank erosion will be published soon. So far in Sisyphe there is a procedure for sediment slide (subroutine MAXSLOPE), it has been extended to graded sediment (this will be in version 6.3). That's all I know on this topic.

Hello,
I checked with my college Michael Schröder and he provided me with an extensive reference list.

Here are some English papers:

The original publications are in German, but I will post them here anyway:

Dear Jean-Philippe,
a physically-based model for bank erosion for non-cohesive sediment has been recently improved, implemented, verified and validated in the framework of a Ph.D thesis in our labs (Ph.D thesis of Andres Die-Moran).
For technical details, I think this thesis will be available to download at the beginning of 2013. All these new developments will be incorporated in the next release of the Telemac System.

all the best,

Pablo

Hello,

At first you can put your developments in your "FORTRAN FILE", any subroutine that you take in the libraries and that is in your fortran file will have priority when compiled.

Please see also the guide to programming in the Telemac system which can be downloaded on this site.

Regards,

JMH
