Shown on the attached page is a cross-section through a weir. The weir is founded on a sand having a permeability of 0.001 cm/sec. For each of the cases shown: 1) Calculate the flow under the structure. 2) Calculate the uplift pressure acting on the base of the structure. Construct a plot of the uplift pressure on the base of the structure versus distance similar to the one shown below. Plot the results of all three cases on the same plot. 2000 1500 Uplift Pressure (psf) 1000 500 0 50 1 40 30 20 10 0 Distance from Toe (ft) 3) Calculate the exit hydraulic gradient (at the toe of the structure). 50 200 225 50 7 $ 3 5.
