WebThe hydraulic radius, Rh, is defined as the area of the cross section divided by its wetted perimeter. Where the channel or canal is of regular cross section, and the depths at the ends of the course are equal, the area and the wetted perimeter will be constant through-out the course. In irregular channels, the area and the wetted perimeter at WebThe characteristic length-scale for a channel of width w and depth h is the hydraulic radius, Rh = wh/P, where P is the wetted perimeter. For an open channel P = (2h + w) and for a closed conduit P = 2(h+w). As a general rule, open channel flow is laminar if the Reynolds number defined by the hydraulic radius, Re = URh/ν is less than
