A dam is constructed to retain water as shown below over a sand layer of $12\mathrm{m}$ height. The flow net is sketched. The equivalent permeability $\mathrm{k}$ is given as $4\times 10^{-4}\mathrm{cm}/\sec$. (a) Determine the flow rate q under the dam. (b) Find the water pressure under the dam at point A located at the base of the dam and at point $\mathrm{K}$ located $6\mathrm{m}$ below the river bottom.
