a dam that is curved in the horizontal plane and usually built of concrete, in which the horizontal thrust is taken by abutments in the sides of a valley. Arch dams must be built on solid rock, as a yielding material would cause a failure
arch dam in American English
noun
a dam resisting the pressure of impounded water by an arch principle, esp. a dam having in plan the form of a single arch abutted by natural rock formations
