What is the hydraulic radius?

Hydraulic radius refers to the ratio of the cross-sectional area of a flow channel to its wetted perimeter. This value is an indicator of the efficiency of flow within the channel.

Engineers and hydrologists use hydraulic radius to analyze the hydraulic performance of rivers, streams, canals, and even pipes.
