韩国京仁阿拉航道泥沙技术咨询

首先从航道泥沙淤积原因、减少航道淤积措施、泥沙原型观测方法、流域泥沙疏导措施、三峡工程泥沙研究等5个方面总结了中国水利枢纽工程航道泥沙治理的技术、研究与实践。指出了韩国京仁阿拉航道4个关键泥沙问题:流域产沙输沙估算与观测,航道输沙能力复核与泥沙监测,渠首防沙工程与非工程措施,航道泥沙疏浚与回淤评估。最后提出了京仁阿拉航道泥沙观测、治理与研究一揽子建议。

Technical consultation for sediment management of Korea Gyeong-in Ara Waterway

Technologies, researches and practices of waterway sediment management during water complex construction in China are summarized in terms of reasons of sediment deposition in waterway, measures to reduce sediment deposition, methods of sediment measurement, measures for prevention and control of watershed sediment erosion and studies on sedimentation of the Three Gorges Project. Four major issues related to sediment of Gyeong-in Ara Waterway are pointed out, including estimation and measurement of sediment yield and transport, checking of sediment transport capacity and monitoring of sediment movement, structural and non-structural measures for sediment prevention of canal intake, and waterway dredging and estimation of sediment deposition recovery. Finally, a number of suggestions for sediment measurement, management and study for Gyeong-in Ara Waterway are proposed.
