A civil engineering firm asked to check the dimensions of a proposed dam to be constructed on a river. The dam would have a height of m, width of m and a thickness of m. The dam is to be constructed of concrete with a density of kg−3. The coefficient of friction between the base of the dam and the riverbed is = 0.8. A hydraulic engineer needs to Sketch the dam showing all forces acting on it to aid calculating the required; i) thickness to prevent sliding ii) to prevent tipping. Taking R as the normal reaction from dam’s contact with the impermeable surface, and S is the frictional force resisting sliding. Evaluate the ability of the subsurface wall to resist the forces exerted by liquid.
