I want to put a above ground pool near a retaining wall and wonder how the weight of the water will be distributed underground. The retaining wall is 6 feet high. The pool is round and 10 feet in diameter. The water is 42 inches high. The closest part of the round pool is 5 feet from the retaining wall. Is the force of the water going straight down so there is no effect on the retaining wall or does the force of the water radiate outSo it will still push against the retaining wall? Thanks
