Hydropower Engineering past question

Check the stability of dam against overturning, sliding and material failure (stresses) with respect to worst location assuming that in addition to self weight, 25% of mass of dam will act as horizontal component (from upstream side) whereas 15% as upward vertical component as seismic load and will act at the CG of the section. Assume unit weight of the concrete as 24 kN/m³, allowable compressive stress in foundation and concrete as 2,500 kN/m² and 3,000 kN m², angle of friction between concrete and foundation as 36° and unit shear resistance between foundation and dam as 700 kN/m².
