Arch Dam

An arch dam is a type of dam that is curved and commonly built with concrete. The arch dam is a structure that is designed to curve upstream so that the force of the water against it, known as hydrostatic pressure, presses against the arch, compressing and strengthening the structure as it pushes into its foundation or abutments. An arch dam is most suitable for narrow gorges or canyons with steep walls of stable rock to support the structure and stresses. Since they are thinner than any other dam type, they require much less construction material, making them economical and practical in remote areas. The development of arch dams throughout history began with the Romans in the 1st century BC and after several designs and techniques were developed, relative uniformity was achieved in the 20th century.

Famous quotes containing the words dam and/or arch:

    The devil take one party and his dam the other!
    William Shakespeare (1564–1616)

    Men seem anxious to accomplish an orderly retreat through the centuries, earnestly rebuilding the works behind them, as they are battered down by the encroachments of time; but while they loiter, they and their works both fall prey to the arch enemy.
