Measurement of Stream Discharge by Wading

Non Standard Conditions•Use of 0.6 and 0.2/0.8 methods assume velocity profile islogarithmic.•Velocity should decrease closer to bottom due to friction•If velocity at 0.8 depth is greater than velocity at 0.2 depthor if velocity at 0.2 depth is twice the velocity at 0.8 depththen the velocity profile is considered abnormal and thethree-point method must be used.
