基于冲淤判定因子的长江重庆九龙坡河段汛后走沙规律研究
Study of sediment-flushing state in Chongqing Jiulongpo Reach of Yangtze River based on scouring-depositing indicator
摘要
Abstract
Based on the measured data, it is showed that U3/h can be used as an indicator for determining the scouring or depositing state in the Chongqing Jiulongpo reach, and U 3/h = 0. 24m2/s3 is the critical value when sediment will be flushed. U3/h in Jiulongpo reach is calculated by a 3D flow numerical model when no measured data are available, whieh is used to study sedimentation in the Chongqing Jiulongpo reach.关键词
