5 Stream bank zones When considering bank erosion, it is useful to split the river into 3 zones (Figure 4): Bank toe zone- The section below the water surface at normal flow conditions. Upper bank zone- The section above the water surface at normal flow conditions Riparian zone- the land running adjacent to the river channel – around 10 m wide.The character of this zone is
