Consider the rectangular prism concrete gravity dam of unit length shown in the figure given below. The specific weight of water is $=9810\frac{N}{m^3},$ and the specific weight of conerete is ${}_c=2\mathrm{.}47.$ Assume nio cartquake, no wind and no water waves. Neglect the resisting foree ffects of soil sections AB and DC in stability analysis of the dam. The friction factor between the bottom$-$foundation surface $($BC$)$ of the dam and the foundation soil surface is $ff=0\mathrm{.}70.$

Check the stability of the dam for overturning and horizontal sliding along the foundation surface $($line BC$).$ Note that overstress analysis for both soil and concrete is not required.

But please consider uplift force for the concrete dam due to soil
