Problem 5. Hydraulic Conductivity (K) varies from aquifer to aquifer, from liquid to liquid, from location to location, from direction to direction, and from temperature to temperature. When the hydraulic conductivity is a continuous function of depth, the average hydraulic conductivity (K) can be shown as the function below where Z is the depth and b is the thickness of the saturated medium. = hydraulic "conductivity R = + √²²²₂²₂²² dz You are hired as a consultant engineer to calculate the hydraulic conductivity of a soil stratum where the hydraulic conductivity of the soil at the surface is 2E-3 cm/sec. It uniformly reduces to 4E-4 cm/sec at a depth of 22 meters as shown in the schematic below. If the water table is 3 meters below the surface: The average hydraulic conductivity of the stratum is----- ------meters/day.
