Brink as a device for measurement discharge for partially filled circular channel

open access: yesAin Shams Engineering Journal, 2013
Many devices are fabricated to measure discharge in circular open channel. The flow over a free overall (brink phenomenon) can be used as a device to measure discharge in open channels with known the end depth.
