Spillways may mimic pounding waves, storms, floods, water streams (the stream or river bed).
Spillway - a device capable in a short time to throw a large amount of water into the frame. They are usually used by the running podiums - the slopes along which water disperses to objects of scenery and actors. Each spillway and feeding podium is mounted on a frame on special load-bearing installation structures, capable of withstanding the estimated mass of water and the dynamic loads arising at the time of water discharge. When you are in the water streams of people, you need the participation of the stunt maker to develop the scene.
