Abstract: River closure is the key engineering issue for the construction of hydropower station, and the hydrological monitoring achievements are the basic messages for fiver closure. Some traditional methods are adopted in the hydrology monitoring of Xiluodu hydropower station and the application of new technologies is also emphasized. The successful implement of these monitoring technologies is not only helpful to the triumphant realization of fiver closure, but also significant to the mo- nitoring of similar rivers in the future.

Key words: river closure , monitoring technology , discharge site from the closure gap ;

摘要： 截流是水电站工程建设施工的关键工程,而水文监测成果是截流重要的基础信息。溪洛渡水电站截流水文 监测,有传统的方法,更突出了一些新技术的应用。这些监测技术的成功实践,既为本次截流的顺利实现提供了帮 助,也为以后在类似河流上开展监测贡献了有益的经验。
