The gravity dam whose section is shown has been designed to include a spillway so that the maximum upstream water depth is 1 m above the top of the section. Tailwater depth under design conditions is 5 m. Considering the slope of the sides of the dam, determine the dimension of the base. Compute the factor of safety against sliding and overturning. Neglect hydrostatic uplift. The coefficient of friction is 0.65.
