Hello,

I am currently working on a project related to flood inundation. We built some embankments at the side of the river. And when the flood is coming, the embankment will be broken and the flow will enter the floodplain area. So the inflow boundary condition should be the embankment-break discharge from the river.However, this discharge should be calculated by coupling the 1D simulation of the river and the 2D simulation of the floodplain area. I am wondering if T2D can be coupled with Mascret 1D to simulate such flood inundation case?

Regards
LIN

I am trying to figure out some other solutions. I am looking forward that TELEMAC can solve such issue on flood inundations. Currently, I know the MIKE module can couple the 1D and 2D in longitudinal way. Regards LIN

If possible I would also be interested to learn more about your project and test case, as I also work on similar subjects. Best regards, Zied
