If you get sea sick on a boat look at the horizon. It brings your vestibular system in sync with your visual input. If you look inside the boat your visual and vestibular systems are out of sync.
The same could have happened to you on the coach - the river gave you something distant to fix your eyes on because of the visual appeal, while other objects did not offer the same point of stability because they were not attractive enough for you to fixate of them or not distant enough to provide stability.

This makes more sense. I didn't know it. This could be the real reason.
I was once on a public coach in a mountain area and was feeling extremely motion sick/nauseating because of all ups and downs and circles of the way. I was just trying to hold off the vomit as long as I could. Suddenly after a turn I saw the river flowing through the glass window of the coach and right there that feeling stopped. It was a sudden calm just by looking at that river water.
It was weird so I did experiment with it. If I looked away nausea came back after a few moments. Did it a few times. Finally I held on to keep looking at the river to keep feeling better.
It may be unrelated to this theory but I don't have any other explanation.
