open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear team,

I was wondering if you help me because of I setup Telemac2d-Sisyphe but I do not how I used a morphological factor = 10 I want to study the evolution of the bottom over an extended period, can you explain in detail how the morphological factor can help me.



I have hydrographs on a daily basis that I can use to evaluate the evolution of the fund in several months and that you have different bathymetric surveys to compare, but on different dates.

Hello,

Reading quickly the SISYPHE user manual, e.g. wiki.opentelemac.org/doku.php?id=documentation_v8p1r0
there is the reference [29] which may help you. You can find the TUC 2012 proceedings here : www.opentelemac.org/index.php/2012

Personnal advice: please post in the right section (SISYPHE here).

Hope this helps,

Chi-Tuan

Hello,

in case of inland waters (rivers) the handling of the morphological factor is a little different to tidal influenced waters. The hydrograph is compressed by the morphological factor. It is described e.g. in S.Wurms & P.M. Schröder (2012)
"Evaluation of strategies for the acceleration of morphodynamic simulations
against the background of waterways maintenance" River Flow 2012 – Murillo (Ed.), © 2012 Taylor & Francis Group, London, ISBN 978-0-415-62129-8
We have good experiences for morphological factors up to about 10. But we always check the influence of this long term strategy by comparison of simulations with and without morph. factor for a significant time period.

best regards,
Rebekka
