Capillary Rise in Layered Soils

Capillary rise tests were conducted on soil columns containing of three layers sandy soils with coarser over finer to investigate the effect relatively interlayer. The capillary height, rate, and water distribution observed in laboratory four layered columns, two homogeneous (without interlayer) serving as controls. final maximum height column interlayer was larger than that without when laid around entry value underlying soil. content not continuous entire profile interlayer, a small matric suction gap fine between
