Question
Determine the effective vertical hydraulic conductivity, keff, of the rectangular prismatic composite soil
sample that is composed of soil A and soil B. Soil A has a hydraulic conductivity, k4, of 1x10 cm/s, and
Soil B has a hydraulic conductivity, kB, of 1x106cm/s. Soil A and Soil B both have exactly the same
height, width, and thickness (L=12cm, 11-4cm, 8cm). Assume porous stones are placed at the top and
bottom of the composite soil sample so that the flow of water is equally distributed to both soil sides.
