Websedimentation of the point bars this promotes bifurcation in rivers. Bifurcation of channel changes to midland point bar with the dynamic change of flow and sediment. Erosion, sedimentation and flow govern the formation of point bars. Their impacts serve as important input to the formation of midland point bars. 1.3.

Sweep will be retarded where the upper sections of point bars form mud sheets along lateral accretion surfaces ( Figure 5c, Figure 7 ). These are inclined surfaces formed by the lateral growth of the point bar as the meander loop migrates. WebPoint bars increase the erosion on the opposite side of the river, causing it to further push the river’s course off to the side. These close-up images show a location on the Mamoré …
WebMar 12, 2024 · The formation of counter point bars has been linked to downstream translation of meander bends (Parker, 1996). Bend translation refers to a lateral shift in bend location that is not associated with a significant increase in its amplitude and arc length (e.g., Daniel, 1971 ; Hooke, 1984 ; Fig. 1 ).
