金沟河流域渠首及上游泥沙沉积分析估算

Analysis and Assessment of Head and Upstream Sedimentation of the Jingou River Basin

金沟河是一条多泥沙河流,泥沙问题是流域管理单位工程运行的主要问题。分析金沟河红山头渠首及以上河段的泥沙量、泥沙构成、泥沙的输移规律、金沟河红山头渠首以上流域的产沙特性,估算出独石化从金沟河红山头渠首上游年引水0.3×10~8m^3,探讨泥沙沉积对引水总干渠运行所产生的影响。

Jingou River is a silty river, and sediment problem is the main problem for operating the projects of the basin management sector. This paper analyzed the sediment quantity, sediment composition, sediment transport laws and the sediment yield characteristics of the canal head and upper areas of Hongshan Hilltop in the Jingou River basin, and estimated that an amount of 0.3×10^8m^3 water was needed by Duzishan Petrochemical Corporation from the canal head and upstream areas of Hongshan Hill- top of Jingou river so as to discuss the impact of sedimentation on the water diversion projects of the main channel.
