Bed forms and vegetated banks play significant roles on flow structure natural streams and rivers. However, the impact of bank vegetation on flow structure in a range of river environments included bed forms seem to remain unexplored. The objective of present research is to investigate the interaction of pools and vegetated banks on turbulent intensities and Reynolds stresses in a narrow flume. Laboratory experiments were conducted in a flume of 8 m long, 0.4 m wide and 0.6 m deep. ADV was used to measure flow velocity in 3D with a sampling frequency 200 Hz. The channel bed form was covered by gravel with a median size of 10 mm. Also, the flume walls were covered by rice stems. The experiments were carried out for four crest slopes, two aspect ratios and ten runs included vegetated and bare banks. Results revealed that the effect of crest slope change in decelerating flow is more important than that in accelerating flow. For angles of 15 and 20 degrees the negative values for velocity were observed, leading to reversal flow (flow separation). Vegetated banks not only increased the Reynolds stress values, but also generated the negative values near the water surface. Quadrant analysis illustrated that the negative values were due to inward and outward contributions. Small aspect ratio caused maximum Reynolds stress occurs near the bed, however, with increasing aspect ratio the maximum values of Reynolds stress and turbulent intensities moved toward the water surface.
