Hydraulic Depth

hydraulic depthHydraulic depth, abbreviated as \(d_h\), also called hydraulic mean depth, is the cross section area of water in a pipe or channel divided by the wetting perimeter.


Hydraulic Depth formula

\(\large{ d_h =  \frac  {  A }  { w }   }\)   


\(\large{ d_h }\) = hydraulic depth

\(\large{ A }\) = area of section flow

\(\large{ w }\) = top width of fluid

Solve for:

\(\large{ A =  d_h \; w  }\)   
\(\large{ w = \frac { A } { d_h}  }\)
