Do we really know how water moves?

Close your eyes, think about what would happen when the spray beats the shore, or the water from faucet comes into your body.
This is a simplest animation showing how water changes its speed after it counters a wall.


The color is speed of water and the water is from left side with 1m/s. Can anyone has ability to simulate it in our brain? I guess its super hard unless you see thousands of similar pictures like this.
So that if the simulation becomes much complex than this one like I mentioned before the spray beats the shore, I guess there will be a big gap between our imaginations and real situations.
