河床垂向渗透系数空间变异性的三维分析
Analysis of Three Dimensional Spatial Variability of Vertical Streambed Hydraulic Conductivity
摘要
Abstract
The vertical streambed hydraulic conductivity plays an important role and has great significance in the study of the conversion mechanism of streambed water and groundwater. This paper studied on the determination of the Yurungqash River a total of 25 test points of vertical streambed hydraulic conductivity using seepage meter method and standpipe method. It studied the spatial variation characteristics of vertical streambed hydraulic conductivity with different depths,vertical directions of river and route directions,analyzed the influencing fac-tors of variability,and summarized the dimensional effect of the variability of the vertical streambed hydraulic conductivity. The results show that Yurungqash River vertical streambed hydraulic conductivity is affected by many factors,including floods,aeolian sedimentation and wa-ter dynamic effect;in different dimensions,the dominant factors of vertical streambed variability of hydraulic conductivity are different. Vari-ability of vertical streambed hydraulic conductivity can not be determined by a single factor.关键词
