(a) Explain what these solid and dashed lines in Figure Q2 represent and their physical
significance in engineering application.
(b) Using the flownet above, estimate the flow rate beneath the dam and the uplift water
pressure at Points A and B on the bottom of the concrete dam.
(c) Using the flownet above, estimate the vertical effective stress at Point C. The saturated
unit weights of soil and unit weight of water are taken as 20 kN/m³ and 10 kN/m³,
respectively.
