Quick Reference

The theory that geomorphological processes always operate in such a way as to achieve the work that has to be done with a minimum expenditure of energy (and maximum entropy). This is typically achieved by the adoption of a certain profile or shape (e.g. a river meander may be that shape best suited for carrying the discharge and sediment with the least loss of energy). See least-work profile.
