The base width of a most economical rectangular channel is 8m, calculate the hydraulic radius of the channel. WebFor a trapezoidal channel with side slopes of 3:1, the hydraulic radius can be approximated as half the depth of flow. Calculate n using the Manning's equation: n = 1 23 × ( d 50 Y ) 0.6 This equation calculates the Manning's roughness coefficient for the gravel-mulch lining based on the median stone size and the depth of flow.
