Flows in embayments are investigated systematically using flow visialization technique and two-component electromagnetic velocimetry. Measured data show that the shape of embayment exerts considerable effect on the development of the vortices along the interface, hence velocity distribution in the embayment at low water depth. Under flood flow condition, flow becomes more complex due to the effect of vertical recirculation formed at the upstream end of the embayment and vegetation on the floodplain.
