A cut bank is an often vertical bank or cliff that forms where the outside, concave bank of a meander cuts into the floodplain or valley wall of a river or stream. A cutbank is also known either as a river-cut cliff, river cliff, or a bluff and spelled as cutbank. Erosion that forms a cut bank occurs at the outside bank of a meander because helicoidal flow of water keeps the bank washed clean of loo… WebRiver Meander.

WebDec 25, 2024 · Meander bends generally have a tendency to change with time toward larger amplitudes and narrower necks. Eventually, the river jumps across the narrow neck during a flood. Such an event is called meander cutoff, or neck cutoff. WebA meander scar, occasionally meander scarp, [1] is a geological feature formed by the remnants of a meandering water channel.

WebThe resulting overbank flow across the meander neck to the adjacent downstream bend led to the creation of an upstream migrating knickpoint, the erosion of approximately 16,000-year-old sediments, and the subsequent meander cutoff. The results of the study indicate that traditional erosion-control measures cannot prevent extreme channel ...
WebThe narrow neck of land between the two neighboring concave banks is finally cut through, either by lateral erosion of the two concave banks or by the strong currents of a flood.
