英文摘要	Daily flow regulation of a hydropower station has a greater influence on waterway transport than long-term regulation such as seasonal or annual regulation. Although a physical model can reflect the influence of daily regulation on waterways exactly, this approach is not economical for smaller hydropower stations. In this study, a mathematical modeling approach was adopted to simulate the influence of daily regulation of the Xiaonanhai (XNH) hydropower station on downstream navigation. A one-dimensional unsteady-flow dynamic model was established by using Saint-Venant partial differential equations with the Preissmann implicit difference scheme and further calibrated with observed hydrological data to ensure simulation accuracy. As a case study, the mathematical model was successfully applied to simulating the hydrodynamics of XNH under daily regulation and estimating the downstream navigability. The results showed that daily flow regulation based on the predicted power demand reduces the flow conditions downstream of the dam during the dry season, which will inevitably impede navigation. This paper presents a practical method for evaluating the navigability downstream of small and midsize hydropower stations. (C) 2017 American Society of Civil Engineers.
