A graphical method of estimating bed shear from measured velocity profiles is presented as an alternative to logarithmic law approach. In the present approach the entire velocity profile is considered as per binary law of velocity distribution i.e., logarithmic law in the wall region and parabolic law in the outer region. The validity of this method has been demonstrated for a typical velocity profile. An analysis has been also made in case of an erroneous measurement of bed level.
