Error analysis of hydraulic radius evaluation in hydraulic calculation [PDF]

open access: yesE3S Web of Conferences, 2021
Hydraulic radius is an important parameter in hydraulic calculation. It is often deemed that hydraulic radius can be replaced by the cross-sectional average water depth when the width to depth ratio (B/H) is greater than a certain value in traditional ...
