open TELEMAC-MASCARET The mathematically superior suite of solvers

I want to model different rainfall for different months. How do I do that? I could find an option for constant rainfall but not time varying. I am trying to develop a hydrodynamic model for a regional lake. There is great variation in distribution of rain through out the year. In some months its zero and in some it is around 250 centimeter. Is there an option to do that in Telemac2d ?

Hello,

So far it is not well formalised, but you can do it by taking subroutine prosou.f (library telemac-2D). In it you will find a sequence : IF(RAIN) THEN...
where an array PLUIE is filled (it is space-varying). At this level you can add a function of time, using either the arguments LT (time step number) or AT, the time.

With best regards,
