), measured in meters, is calculated by using this equation:![y_{c} = \sqrt[3]{\frac{\dot V^{2}}{g\cdot b^{2}} }](/tpl/images/0847/6746/69f04.png)
(Eq. 1)
- Volume flow rate, measured in cubic meters per second.
- Gravitational acceleration, measured in meters per square second.
- Channel width, measured in meters. 
, 
and 
, then the critical depth is:![y_{c} = \sqrt[3]{\frac{\left(15\,\frac{m^{3}}{s} \right)^{2}}{\left(9.807\,\frac{m}{s^{2}} \right)\cdot (2\,m)^{2}} }](/tpl/images/0847/6746/41d58.png)
), measured in meters, is obtained from this formula:
(Eq. 2)
, then the flow velocity in the rectangular channel is:
