$8\mathrm{.}6.$ For the hydraulic structure shown in Figure $8\mathrm{.}19,$

draw a flow net for flow through the permeable layer and calculate the seepage loss in m$3/$day$/$m$.$ Refer to Problem $8\mathrm{.}5.$

Determine the hydraulic gradient at the exit at the front of the dam.

Calculate the hydraulic uplift force at the base of the hydraulic structure per meter length $($measured along the axis of the structure$).$
