1D-2D coupling
« on: October 08, 2019, 04:49:46 am »
Hi All,

I am working on 1D-2D coupled flood model using MIKE Flood.
So far, I have been modeling rainfall using the runoff model in the MIKE11 and the overflow from the MIKE11 flow to the MIKE21. In this case, it seems that only the place with the drainage network linked areas is flooded.
If you have very detailed drainage lines, this won't be a problem, but in practice, there are limits to building all the pipes into the model.
It's a little dilemma here, is it reasonable to give rainfall information only to 1D model or to 2D model?
It seems whether the chicken first or egg first? I would like to hear a reasonable opinion on this.

Thank you for your help in advance.
Kevin.
