Dynamic equilibrium

A natural state of stream stability when channel features persist over time within a range of conditions. Dynamic equilibrium uses a series of self-correcting mechanisms that allow the ecosystem to control external stresses or disturbances, thereby maintaining a self-sustaining condition. For example, a stream is able to consistently transport its sediment load, both in size and type, associated with local deposition and scour.
