open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello, as part of my master's thesis, a flooding event in a tunnel is modeled in a 16 square kilometer catchment area after heavy rain. Telemac 2d is used for the simulation. Can someone tell me whether it is possible to show flooding of an underground tunnel in Telemac 2D? Does anyone have experience with rainfall-runoff models to represent flooding of a tunnel or houses in Telemac 2D and can help me?
Please excuse my english.

Thank you.

Hello Dome_A,
just saw your Topic and wanted to ask, how you managed to implement the heavy rain in your model. Whats the definition of "heavy rain" and how did you solve the problem with the tunnel/houses?
Best regards
Jens
