I just wanted to get some thoughts brewing on how I could build a wave pool for surfing in my back yard. In physics, what topics would I research so I could understand the concepts behind a wave pool? I don't know if any of you surf, but is it possible to create a barreling wave were its hollow in the middle? I would imagine if we could make an oscillating "sea floor" we could make that happen. In general, what materials would one need to build one of these? Thanks for the thoughts everyone. Here is a video of something that I'm after. http://www.youtube.com/watch?NR=1&feature=endscreen&v=fI2cLDEzNUo Here is an article to check out if your interested. http://www.surfertoday.com/surfing/8084-prepare-to-design-your-own-artificial-wave-for-surfing Additionally, I'm looking for the physics involved in a moving wave as opposed to a stationary wave. I want it to operate as close to a real ocean as possible.
