建立了河道型水库一维水动力学模型。选取珠江流域乐昌峡水库进行动、静库容调洪演算，揭示了动库容调洪的负面影响；通过研究不同洪型、不同频率水文组合条件下，水库回水淹没范围、库区洪水传播速度以及调洪过程中动库容变化特性，讨论了水库设计调洪方案的合理性，并提出了更为合理的调洪方案。研究成果可为类似河道型水库防洪调度参考。

The 1D unsteady flow model for river-type reservoir was developed to analyze the flood evolution and the variation of dy‐namic reservoir capacity during the flood regulation .For the Lechangxia Reservoir as an example ,the calculation of flood routing of dynamic capacity and static capacity of river-type reservoirs had been comparatively analyzed of different flood type and frequency . Through 1D unsteady flow model calculation ,the variation and ending situations of the backwater surface profile ,the travel speed of the flood ,and characteristics of dynamic capacity of the Lechangxi Reservoir are demonstrated .On this basis ,the reliability and op‐erability of the design flood scheme was verified and a more reasonable scheme was proposed in this research .The results can provide a reference for developing scheduling scheme of the similar river-type reservoir .
