Hydraulic Depth

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

 

Hydraulic Depth formula
\(\large{ d_h =  \frac  {  A_c }  { w }   }\)
Symbol	English	Metric
\(\large{ d_h }\) = hydraulic depth	\(\large{ ft }\)	\(\large{ m }\)
\(\large{ A_c }\) = area cross-section of flow	\(\large{ ft^2 }\)	\(\large{ m^2 }\)
\(\large{ w }\) = fluid top width	\(\large{ ft }\)	\(\large{ m }\)
