Velocity profiles from Sacramento delta have been used to estimate the longitudinal dispersion coefficient using Taylor and Fischer triple integral methods. The results presented in this paper show that even for large value of the aspect ratio of the streams (i.e. width/depth), vertical shear contributes to the longitudinal dispersion process. The contribution of transverse shear depends upon variation of depth-averaged velocity across the cross-section of the stream rather than the aspect ratio.
