The initial discharge through the conduits is similar to that of a weir. when air is drawn away from above the end over the crest, the discharge starts flowing by siphonic action. The inside of the bend of inverted U-tube is at normal reservoir level.
WebGrass-lined spillways are generally only suitable when the spillway is formed directly on a low-gradient, natural surface.
