摘要
本文研究了刁口流路行水期间,河道演变全过程的泥沙冲淤变化,叠合沙体的发展演变,计算了各阶段不同深度范围的淤积量,从而总结了泥沙淤积分布的特点,提出了新的资料和认识.
Deep analysis and study have been done to distribution, model and rate of scouring and silting of silts, evolution of subdeltas, reworking process and characteristics of scour and fill after changing courses,and changes of subaq-uatic land forms and some other problems about the Diaokou Channel, on the basis of complete and systematic observed data of the channel. The studies of all these problems will undoubtedly provide an important basis for further understanding of formation and evolution of the modern Huanghe River Delta.
This paper summarizes the distribution characteristics of scouring and silting of silts in the Diaokou Channel and tries to point out new knowledge and understanding about the channel, through studying scour-and-fill changes of silts in the whole process of the channel evolution, and development and evolution of superposed sand bodies during water-flowing periods, and through calculating scour and fill volume at different depth extent of each stage.
