Abstract

The friction force that resists the movement of water in conduits is a
function of the irregularity and roughness of the conduit surface. Kruse et
al. (1965) and Heermann et al. (1969) found that the hydraulic resistance
in irrigation furrows is a function of the logarithm of the ratio of the absolute
roughness to the hydraulic radius. They successfuly modeled hydraulic
smoothness (inverse of resistance), defined as the flow velocity V divided
by the shear velocity V*, by an equation developed by Sayre and Albertson
(1961).
