| 摘 要： | 为掌握三峡水库2007年156 m蓄水过程中库区水文河道变化情况，通过观测与分析三峡库区蓄水过程的水沙变化，探讨蓄水过程水位、河道比降及水文泥沙运动的变化规律，为三峡库区175 m蓄水后的水面线对比分析、回水区的界定等研究打下基础，同时也为三峡库区175 m正常蓄水运用后，三峡水库库尾重庆变动回水区河段的水沙冲淤变化、河道走沙规律分析研究提供了条件。

| Abstract: | In order to master the variation of hydrological regime and river channels for TGP Reservoir Area during 156 m impoundment stage in 2007,following work have been done,including observation and analysis on the flow and sediment variation in impoundment stage of the reservoir area,exploration on the variation laws of water level and channel gradient and sediment movement in the impoundment stage,so as to lay a foundation for relative analysis of water surface profiles and the study on definition of backwater ... |
