Flow visualization using photoelasticity has been applied to the two-dimensional flow over a wavy bed. Under the different conditions of the concentration and the temperature, aqueous solution of Milling Yellow dye has been tested in order to obtain the effect of birefringence. The results of shear stress measurement of the flow are compared with the theoretical neumerical solution. ITV has been used for the quantitative evaluation of the photo picture analysis.
