Question

Problem 1: Following figures show geometry of a dam and seepage flownet a) If the length of the dam is 2 km, estimate the quantity of seepage in liter/day (3 points) b) Estimate the exit gradient c) Plot the uplift pressure distribution on the base of the dam. Use EXCEL or MATLAB to plot (2 points) the same. Plot distance on X axis and Uplift pressure on Y-axis with Y axis reversed (increasing in the downward direction). Show a sample calculation by hand. (15 points) 37 m 10 m 1.5 m 9 m Sheet pile 24 m 10-3 cm/sec Impermeable layer 1.5m 10m 24 m
