An accurate estimation of bed shear stress is essential for estimating sediment transport rates in streams, rivers and open channels. Precise velocity measurements were carried out in steady, uniform open channel flows over a rough bed with large scale roughness to compare different methods of estimating bed shear stress. Effect of reference bed level for measurement of water depth which is an important parameter for computing bed shear stress, was investigated.
