$2.$ An alternate design is being considered for the dam above in order to reduce the exit gradient and thus lower the risk of erosion. A $100\text{'}$ long seepage blanket placed on the upstream end of the dam is proposed. Draw the flow net for this design and determine the uplift pressures acting along the base of the dam. Is the resultant of the uplift pressures for the alternative design greater than, less than, or equal to the design in Problem $1.$ Explain why they differ. $($Note: Remember to draw the problem to scale.$)$
