CFD and ALE Coupling to simulate a "free water surface"

I try to simulate a water reservoir with a free water surface.
Therefore I want to couple the turbulent flow model (RANS, k-epsilon) with the ale-module.
I tried so far a bunch of approaches, but never suceeded (If i neglect the free water surface and simulate only the turbulent flow - no problem). I dont want to use the multiphase flow approach, since the moving interface needs a high vertical mesh refinement and I'm not interested in any flow simulation of air.
The following file shows my approach: ALE and Turbulent flow themselves may be solved, but whenever I couple both the solution does never converge. A simplified 2D-Model worked fine.
I hope that someone may help me. Another approach would be fine too (eg. remeshing every few seconds with a modified geometry?) .
Thank you very much!
