Mean Depth
Mean depth, abbreviated as \(h_m\), is the average water depth in a stream channel or conduit computed by dividing the cross-section area by the surface width.
Mean Depth formulas
\(\large{ h_m = \frac{ A_c }{ T } }\) | |
\(\large{ h_m = \frac{ v^2 }{ g \; Fr^2 } }\) | (Froude number) |
Where:
\(\large{ h_m }\) = mean depth
\(\large{ A_c }\) = area cross-section of flow
\(\large{ Fr }\) = Froude number
\(\large{ g }\) = gravitational acceleration
\(\large{ T }\) = top of water surface width
\(\large{ v }\) = velocity of flow
Solve for:
\(\large{ T = \frac {A_c} { h_m } }\)
