ABSTRACT:
A flow control vane in a moving current of water causes lowering of the surface of water rearwardly of the vane. The vane is placed transversely across the front of a surface skimmer in an oil boom apparatus used to collect and remove floating oil from a body of water moving relatively towards the skimmer. The vane causes a stable pool of water to form behind it, the pool having a surface level lower than surrounding water, and improves operation of the skimmer. The vane is an upright and inclined web element having a forwardly curved upper leading edge and a rearwardly curved lower trailing edge.
