<p>A dissipator basin for reducing the kinetic energy of water exiting from steeply sloped highway culverts, spillways and the like which is especially useful in mountainous country. A substantially rectangular basin is provided with a massive impact block shaped so that water from the culvert strikes the underside of an upwardly and rearwardly facing projection which causes the water to be swept downwardly and rearwardly as a downward vortex which tends to dissipate the kinetic energy as heat.</p> |
