【Abstract】 A hydraulics model test has been performed for forebay of the Huinanzhuang pumping station located at Beijing section of middle routed of South-to-North water transfer project. The results are given for flow pattern of the forebay and total diffusion angle, inner and outter flow pattern of the forebay and behavior of vortexs, water level and wave of water line in the forebay. The feasibility and rationality of hydraulics design for the forebay are verified.更多还原
