I am interested in building a small lazy river to be designed with my future pool. I can't find much out there on lazy river pools. I do know that they have to be at least 5' wide and 2'6" deep for comfort, but I don't know how much (shotcrete/rebar) reinforcement is needed so it won't crack. I also don't know how many jets-per-length I would need to maintain flow. The pool design would be a simple rectange(pool) with a smashed circle(lazy river) connected to the top.
If anyone could point me in the correct direction, it would be most appreciated.
