Data and the figures

A one-month reservoir erosion event contributed 24% of decadal total amount.Downstream SSC increased by a factor of >200 and riverbed shifted from erosion to deposition.Episodic reservoir erosion will be more frequent with more silted-up reservoirs worldwide.

单次为期一个月的水库侵蚀事件，其贡献的泥沙量占十年总侵蚀量的24%。下游悬移质泥沙浓度（SSC, suspended sediment concentration）增幅超过200倍，河床由侵蚀状态转为淤积状态。随着全球范围内水库淤积程度日益加重，突发性水库侵蚀事件的发生频率将愈发频繁。
