Mean Depth

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Mean depth is the average water depth in a stream channel or conduit computed by dividing the cross section area by the surface width.

FORMULA

\(h_m =  \frac { A }  { T  }  \)

Where:

\(h_m \) = mean depth

\(A  \) = area of cross section flow

\(T  \) = top water surface width

Solve for:

\(A =  h_m \; T  \)

\(T =  \frac {A}  { h_m  }    \)
