Summary

Whenever there is flow of water in an alluvial channel, the water entrains and transports sediment. The entrainment and transport of sediment require work that flow must perform, and to perform the work requires energy. The water has potential energy due to elevation, which is transformed to kinetic energy part of which is utilized to do this work and part is dissipated to overcome boundary and bed friction. The time rate of potential energy expenditure is the stream power, which plays a fundamental role in the evolution of a fluvial system. Using the theory of stream power, this chapter derives constraints for hydraulic geometry.
