Problem 1: A permeable soil layer is underlain by an impervious layer as shown below. Knowing that k = 6 x 10-³ cm/sec for the permeable layer. Given H = 5.4 m, calculate the rate of seepage through this layer in m³/hr. if: a = 5° α-70 a = 9° a = 12° Draw a chart a vs. q (i.e. a on the x-axis, and q on the y-axis) and discuss how the slope angle (a) impact the flow rate and explain the reason for such behavior.
