This experiment controls most valiables still and only tests how wave responds to gravel. The gravel set-up is shifted in size, layer sequence, height, and shape(slope). Through the experiment, I got a better understanding of how wave reflection occurs and how to use gravel to control waves.
I found several surprising facts. For example, when the gravel’s height is surpassed the mean water surface, it works more effectively than enlarging the gravel size or changing the shape(slope).
