Abstract

The invention relates to a self adjusting weir 10 for use in a body of water that can be used to create a head rise in the body of water and autonomously rotate about a horizontal axis 26 in response to hydrostatic pressure exerted on the weir. The weir comprises a buoyant barrier 12 rotatably connected to a fixed support structure 14. The barrier has a downstream side 24, an upstream side 22, a base region 18 and a top surface 28, wherein the base region is rotatably connected to the support structure about an axis along the length of the barrier. The barrier may comprise a manifold 50 through which water can be introduced into the interior of the barrier. The barrier may comprise sealing members which co-operate with the support structure and scour skirts 46 attached to the base of the barrier.
