The point at which a large flood causes an abrupt shift leading to the carving of a new channel is known as a threshold. This is because it represents a point of significant change in the system, where small changes in input (such as additional water flow) can lead to a large and permanent change in the state of the system. The other choices, such as dynamic equilibrium and metastable equilibrium, do not capture the sudden and irreversible nature of this type of change.
