- Description
- This paper presents laboratory experiments conducted in a mildly curved channel to determine the influence of bend curvature and bank vegetation on flow. Measurements of velocities and water surface elevations on a dense grid allowed the quantification of the most significant force balance components. The initial experiment without vegetation showed that the water surface experienced transverse tilting due to centrifugal forces and accompanying longitudinal flattening and steepening typical of meander bends. This led to higher downstream velocities along the outer half of the bend. Bank vegetation reduced outer bank velocities and caused straighter streamlines. Vegetation also enhanced centrifugal forces near the entrance of the downstream bend, highlighting the importance of vegetation placement on the outcome of rehabilitation works.
