Hydraulic Radius of a Triangular Channel
Hydraulic radius, abbreviated as \(r_h\), is the area cross-section of water in a pipe or channel divided by the wetting perimeter. The hydraulic radius (R) of an open channel, including a triangular channel, is a measure of the channel's efficiency in conveying flow. It is defined as the cross-sectional area of flow divided by the wetted perimeter.

Symbol | English | Metric |
\( r_h \) = hydraulic radius | \(ft\) | \(m\) |
\( A_c \) = area cross-section of flow | \(ft^2\) | \(m^2\) |
\( P_w \) = wetting perimeter | \(ft\) | \(m\) |

\( r_h = z\;h^2 \;/\; 2\;h \; \sqrt{1 + z^2 } \) | ||
Symbol | English | Metric |
\( r_h \) = hydraulic radius | \(ft\) | \(m\) |
\( z \) = width of channel slope | \(ft\) | \(m\) |
\( h \) = depth of fluid | \(ft\) | \(m\) |
