The foundation or abutments for an arch dam must be very stable and proportionate to the concrete. There are two basic designs for an arch dam: constant-radius dams, which have constant radius of curvature, and variable-radius dams, which have both upstream and downstream curves that systematically decrease in radius below the crest.
A dam that is double-curved in both its horizontal and vertical planes may be called a dome dam. Arch dams with more than one contiguous arch or plane are described as multiple-arch dams. Early examples include the Roman Esparragalejo Dam with later examples such as the Daniel-Johnson Dam (1968) and Itaipu Dam (1982).

Types of Arch Dams Explained in Detail. A constant radius arch dam is that in which the radii of the outside curved surface are equal to all elevations from top to bottom. The centers of all such circular arch’s called extrodos wall, therefore evidently lie on one vertical line.
