2. For the sample below of a 5 ft radius: a) calculate hydraulic gradients for all three soil layers, b) calculate the seepage rate, c) draw the diagrams of total and effective stresses and pore water pressure, and d) find the maximum water elevation, H, before layer 1 starts heaving. Use the following soil properties: Soil 1 - Ysat=115 lb/ft³ and k=0.006 in/sec, Soil 2 - Ysat=125 lb/ft³ and k=0.003 in/sec, Soil 3 - Ysat-120 lb/ft³ and k=0.016 in/sec.
