Hi Rob, you are correct, if I bounce a bucket of water up and down for a short period of time, then the free surface will stabilize after some initial slopping.

However, if I continuously keep bouncing the bucket up and down, does the free surface stop sloshing? 

This was actually an experiment explained in this paper by Chiba et. al. (2016),

Another paper by Xue et. al. (2019), used the plot from this experiment to validate their numerical model,

I was attempting to do the same by validating my sloshing numerical model but facing problems.
