The dam's weight counteracts that force, tending to rotate the dam the other way about its toe. Dams can also be created by natural geological forces. The inward compression of the dam by the water reduces the lateral (horizontal) force acting on the dam. Two dams called Ha-Uar running east–west were built to retain water during the annual flood and then release it to surrounding lands.
