The helicoidal flow also plays a role in this process by acting as a cross channel component that moves the sediment to the other side.
[3] In addition, point bars act as topographic obstructions once formed that further drive flow into the opposite bank, creating a positive feedback loop.
Typical features found in river channel migration are point bars, cut banks, meanders, floodplains, and oxbow lakes.
Over intermediate time scales, planimetric resurveying and repeated cross profiting are utilized.
[4] In order to model river channel migrations over time, orthogonal functions of erosion path lines can be generated for individual point bar complexes.
