An arch dam is most suitable for narrow canyons or gorges with steep walls of stable rock to support the structure and stresses.[2] Since they are thinner than any other dam type, they require much less construction material, making them economical and practical in remote areas. In general, arch dams are classified based on the ratio of the base thickness to the structural height (b/h) as:[1] Arch dams classified with respect to their structural height are:[1] 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.
