At the initial design phase, the dam of Reservoir 1 (Dam 1) was suggested to be a simple gravity dam with a rectangular cross-section built from concrete, with a density of 2,350 kg/m^{3}. When the reservoir is full, the water level and the top of the dam wall are at the same height.
a) Determine the hydrostatic force on a unit width (1 m) of dam wall when the dam is operating at its maximum capacity (when the reservoir is full).
b) Determine the minimum dam wall thickness by applying the “middle third rule” assuming a unit width of dam for calculation. Include uplift as a hydrostatic pressure distribution acting vertically upwards on the base.
