Critical depth of flow

WebMay 4, 2024 · The depth at which the specific energy was minimum for a given discharge is as the critical depth and the corresponding flow is as the critical flow. In channels the discharge and flow depth have a unique relationship when the flow is critical. Utilizing this unique relationship, several flow-measuring devices have been developed. http://uon.sdsu.edu/online_calc.php
