| 摘 要： | 输沙需水是维持主槽不萎缩的重要条件。本文在考虑黄河下游非汛期冲刷、大漫滩洪水淤滩刷槽冲淤特点的基础上,根据非漫滩洪水水、沙及河道冲淤关系,研究提出了维持主槽不萎缩的输沙需水计算方法,并结合小浪底水库典型水沙调节方案,分析计算了黄河下游维持主槽不萎缩的输沙需水量变化范围。研究表明,主槽维持规模、来沙量、水沙过程是维持主槽不萎缩输沙需水的重要影响因素,小浪底水库合理调控黄河下游水沙搭配关系后,维持主槽不萎缩的输沙需水可明显减少。

| Abstract: | Water demand for sediment transport is very important to maintain the main channel without withering.Based on the characteritics of erosion in non-flood season and deposition on floodplains and erosion in the main channel for big over-floodplain floods in the Lower Yellow River,the method to calculate the water demand for sediment transport to maintain main channel with no-withering is proposed in this paper.In addition,the extent of water demand for sediment transport corresponding to the same incoming sed... |
