What causes meander cutoffs?

Excess sediment from upstream erosion is a major cause of cutoffs. Many meanders are cut off because stream energy is insufficient to carry incoming sediment through a bend. When a sediment plug forms on the entrance to a mean- der bend, the stream will cut through the flood- plain or point bar.

How meanders form develop are cut off and then are abandoned?
