梅江五华河近30年河床演变的研究

Study on fluvial process of Wuhua river in Meijiang recent 30 years

五华河河子口水文站近年来因河道采沙造成河床下切严重,根据梅江五华河河子口站近30 a的水文、泥沙资料,分析了断面动力、沉积及河床的演变过程,并讨论了其影响因子。提出了一些值得思考的问题,建议进一步分析河床10～100 a尺度的滩槽演变及影响因子。

Because river sand mining caused serious riverbed deepened, cross-section power, sedimentation and the evolution of riverbed were analyzed according to the data of hydrology and silt in Wuhua river station of Meijiang river,and its impact factors were discussed. This paper raised some worthy of considering issues and recommended further analysis of the riverbed 10-100 beach scale trough evolution and impact factors.
