Spillways in
the UK known as overflow channels. It has now become Armenia’s one of the best
attraction. These channels are actually structures that provide controlled
release of flows from a dam into an area downstream.
Unfortunately
this glory hole for the Kachut Dam has inadequate capacity. The space available
for a new spillway, between the dam and a water supply tunnel, is too limited
to provide the capacity needed for a normal ungated spillway. The Armenian
State Committee of Water Systems is looking to address this problem with the
use of fuse gates. This construction is part of the country’s Dam Safety
Project, a World Bank financed, nation-wide program for improving the safety of
existing dams.
They release
floods so that water does not over top and damage the dam; water does not
usually flow over a spillway unless there is a flood. Typically spillways are
round; this star-shaped one is found at the Kechut Reservoir near Jermuk in
Armenia.

A spillway is a structure used to provide the controlled release of flows from a dam or levee into a downstream area, typically being the river that was dammed. In the UK they may be known as overflow channels. Spillways release floods so that the water does not overtop and damage or even destroy the dam. Except during flood periods, water does not normally flow over a spillway.
