Abstract: In hydropower projects, it is very popular to investigate several alternatives of waterway at a design stage, in point of not only alignment but also connectivity of conduits, number of wye branches and turbines. However, there are few satisfactory methods to analyze transient hydraulic phenomena such as surging and water hammer for arbitrary waterways. In this paper, a method based on a network theory is proposed to analyze such hydraulic phenomena, and its validity is proven by comparison with real data obtained at a pumped storage power station in service.
