崖羊山水库一维泥沙数学模型参数率定与验证

水库泥沙淤积影响水库兴利效益的发挥，威胁水库的使用寿命。本文根据水动力泥沙模型基本方程，在一定的假定条件下，对一维非均匀流不饱和输沙模型进行简化，并分析了利用水库实测资料对模型参数进行率定与验证的方法。最后，利用崖羊山水库资料作为实例，通过与实测资料对比验证所率定参数的合理性，为今后进行崖羊山水库泥沙淤积计算提供依据。 Reservoir sedimentation affects the reservoir benefits and threatens the reservoir life. Based on the basic equations of the hydrodynamic and sediment mathematical model and under certain assumptions, the one-dimensional model of non-uniform flow and non-equilibrium sediment transport model was simplified, and the model parameters were calibrated and verified using the observed data of the reservoir. In this paper, the model was applied to Yayangshan Reservoir and verified the parameter feasibility according to the measured data in the reservoir, which can provide reference for the sedimentation calculation of the Yayangshan Reservoir in future.
