Patent ID: 7192217

Claim:
A baffle apparatus for directing fluid flow to reduce damage to an open flow channel energy dissipating basin that includes an inlet, an outlet, a floor, a sidewall that extends upward from an edge of the floor, and an opposing sidewall that extends upward from an opposing edge of the floor defining an open flow channel energy dissipating basin interior with an energy dissipating basin span between the sidewall and the opposing sidewall, comprising: (a) a deflector structure that is generally planar and is adjustably positioned substantially transverse to a downstream direction flow in the energy dissipating basin, said deflector structure spanning between the sidewall and the opposing sidewall above the floor, wherein said deflector structure is positioned to direct flow in the energy dissipating basin to flow in a downstream direction from an opposing upstream direction adjacent to the energy dissipating basin floor; and (b) a channel deflector structure guide wherein said planar deflector structure is slidably engaged with said channel deflector structure guide such that said planar deflector structure slides within said channel deflector structure guide to a selected distance above the energy dissipating basin floor with the distance fixed by an adjustable attachment positioned within said channel deflector structure guide.
