Labyrinth weirs provide an economic option for flow control structures in a variety of
applications, including as spillways at dams. The cycles of labyrinth weirs are typically
placed in a linear configuration. However, numerous projects place labyrinth cycles along
an arc to take advantage of reservoir conditions and dam alignment, and to reduce
construction costs such as narrowing the spillway chute. Practitioners must optimize more
than 10 geometric variables when developing a head–discharge relationship. This is …
