| 摘 要： | 为治理尾闾河道萎缩提供技术支撑,采用实测资料分析与理论探讨相结合的方法,研究了尾闾河道断面形态变化及其与水沙过程的响应关系.结果表明,1986年后,黄河口水沙过程变异,尾闾河道平滩流量和平滩面积大幅度减小,平滩宽深比有所增大,断面形态变的宽浅；2002年后,小浪底水库调水调沙运用,尾闾河道萎缩有所恢复,平滩流量和平滩面...

| Abstract: | For harnessing the atrophy of tail channels,the relationship between the section configuration and flow-sediment was researched using the methods of field data analyses and theoretical study.The results show that,after 1986,with the variation of flow-sediment,the atrophy of tail channels is in evidence,the bank-full area reduce,the width-depth ratio increase,the section configuration become wide and shallow;after 2002,the regulation of flow-sediment of Xiaolangdi Reservoir run successfully,the atrophy of ta... |
