利用一维数学模型计算万州至涪陵河段通航水流条件(水深、流速、比降),并对各蓄水阶段通航水流条件变化情况进行对比分析。研究结果表明:万州至涪陵河段航道均不同程度的受到蓄水影响,并相应产生一定变化,有利有弊。蓄水期水位抬高,流速减缓,对航道有利但也造成部分滩险的泥沙淤积。 The one-dimensional mathematical model was used to calculate the navigable flow conditions (water depth, velocity and ratio) from Wanzhou to Fuling and to compare and analyze the changes of navigable flow conditions at each stage of water storage. The results show that the waterways from Wanzhou to Fuling are impacted by the impoundment to a certain extent, and there are some changes correspondingly, which have both advantages and disadvantages. During the water storage period, the water level is raised and the flow rate is slowed down, which is favorable to the waterway but also caused sedimentation of some beach risks.
