From Fig.3, we see the water pressure inside the dam is influenced by the slope of upstream face; the pressure at the bottom in case one (Fig.3 (a)) is more important than in case two (Fig.3 (b)), and tends towards the downstream face contrary to the second, this distribution is caused by the inclined part at upstream face induced the concentration of pressure at the bottom
