摘要
楠溪江上游跨流域引水将导致下游感潮河段的淤积,应用河口河相关系式预测了下游河道淤积面貌,并通过永宁江引水后的实际淤积情况对计算结果进行了复核,用一维非恒定流数值模型计算分析了径流减少以及河道淤高引起的潮汐、潮流、洪水位等水文要素的变化。
The water diversion that spans Nanxi River valley will silt the fide reach on downriver. An estuarine hydraulic geometry relationship is used to forecast the visage of silt, which is verified through comparison with the actual silt of Yongning River after water diversion. Based on the one-dimension numerical model, the effect on hydrological factor in Nanxi River due to flood reduction and silt has been studied.
