Title: Analysis on Erosion-deposition of Channel and Fluvial Process in the Lower Yellow River in 2000
Abstract: According to monitoring data in the Lower Yellow River from Nov., 1999 to Oct., 2000, the characteristics of water and sediment out Xiaolangdi Reservoir have been analyzed, the erosion-deposition of channel in the lower reaches, bed sediment coarsening, sectional morphologic variation and river regime variation have been studied thoroughly, and the effect of deposition reduction on operation of regulating water and sediment in Xiaolangdi Reservoir has been analyzed and calculated. Simultaneously the effect of water supply to Tianjin urgently from Oct., 2000 to Feb., 2001 on deposition reduction has been also analyzed and studied. It is shown from the results that though water volume into the Lower Yellow River during this period is the lowest in history, the deposition reduction is still 0.216 billion t in the Lower Yellow River, therefore there are no great changes of river regime and dangerous situation of project occurred.
