Also known as -

An unequal-thickness arch dam is an arched concrete dam with thicker concrete sections on both sides of the embankment. When an arch dam is constructed in a wide V-shaped valley, the load on both banks of the arch may be too much. This dramatically improves the stability of the bedrock. The appearance is that the downstream embankment is thickened as it gets closer to the abutment.

Uneven-thickness arch dams are rare in Japan, but the Seirenji Dam (Mie) and the Managawa Dam (Fukui) are examples.
