Effect of anisotropy and groundwater system geometry on seepage through lakebeds

摘要: Abstract Distribution of seepage through lakebeds is controlled partly by geometric configuration the lake and groundwater system interacting with lake. To evaluate effect these factors, conductive-paper electric-analog models were used to analyze a number settings having different configurations. Most analyzed are lakes that do not penetrate system. The width ratio, ratio half thickness system, principal characteristic in this study. Because distribution into uniform across lakebed, concept streamlinecrowding factor developed, determine patterns from characteristics its contiguous Analysis fourteen ratios systems indicates can be defined three general groups patterns, which include flow volumes rates: (1) less than ∼ 0.6 show relatively lakebed; (2) 2.0 change absolute relative streamline crowding near-shore region; (3) greater stable near shore; however, increasing width, increases width. For deep those anisotropic media, decreased, resulting more lakebed.
