Extracted text: A 5.3 m thick of soil consist of three different layers as follows: Layer 1: H = 1.6 m, k = 4.5 m/day Layer 2: H = 2.3 m, k = 3.5 m/day Layer 3: H = 1.4 m, k = 3.1 m/day What is the equivalent coefficient of permeability in the horizontal direction? What is the equivalent coefficient of permeability in the vertical direction? What is the total flow (horizontal flow) q in m³/day, if i = 0.005 and assume 1-m width? TIC
