For the dam spillway shown in Figure 1, draw a flownet at a scale of 1 inch = 10 meters. Using this flownet, estimate the seepage underneath the dam in m/day/m, the uplift pressures acting along the base of the dam, and the resultant force of the uplift pressures. (Note: Remember to draw the problem to scale.)
