Abstract

River bed profiles and depth-averaged velocities are used as basic data in empirical and analytical equations for estimating the LONGITUDINAL DISPERSION COEFFICIENT which has always been a topic of great interest for researchers. The simple model proposed by Maghrebi is capable of predicting the normalized isovel contours in the cross section of rivers and channels as well as the DEPTH-AVERAGED VELOCITY profiles. The required data in Maghrebi’s model are bed profile, shear stress, and roughness distributions. Comparison of depth-averaged velocities and LONGITUDINAL DISPERSION COEFFICIENTs observed in the field data and those predicted by Maghrebi’s model revealed that Maghrebi’s model had an acceptable accuracy in predicting depthnaveraged velocity.
