This static model calculates the normal depth in an open channel assuming uniform flow conditions. The Manning's equation is used to calculate depth given the flow rate and assumed …
WebAs a second means of determining the Manning coefficient, the distribution of velocity in the vertical at gaging stations provides a useful tool. The logarithmic velocity-distribution equation and the Manning equation can be solved for the Manning coefficient in terms of the ratio of the velocities at two-tenths and eight-tenths the depth.
