Abstract: A water simulation system may include a tank, a plurality of fluidic inlets, a plurality of fluidic outlets, and one or more pumps. In operation, the one or more pumps may introduce liquid to the tank through the fluidic inlets and draw liquid from the tank through the fluidic outlets. A pressure at the fluidic outlets may be diffused through the tank by an intake diffusion system having an intake box and an intake plate separating the fluidic outlets from the interior of the tank. A liquid flow may be adjusted for creating swift water conditions in a first portion of the tank and a slower current in a second portion of the tank.
