(Total) Stream power Stream power is the rate of energy dissipation against the bed and banks of a river or stream per unit downstream length. It is given by the equation: $${\displaystyle \Omega =\rho gQS}$$ where Ω is the stream power, ρ is the density of water (1000 kg/m ), g is acceleration due to gravity … See more Stream power originally derived by R. A. Bagnold in the 1960s is the amount of energy the water in a river or stream is exerting on the sides and bottom of the river. Stream power is the result of multiplying the … See more Size of displaced sediment Critical stream power can be used to determine the stream competency of a river, which is a measure to determine the largest grain size that will be moved by a river. In river's with large sediment the relationship … See more • Hydrology • Geomorphology • Erosion • Sediment transport • Shear stress • Hydrogeomorphology See more Although many authors had suggested the use of power formulas in sediment transport in the decades preceding Bagnold's work, and … See more It can be derived by the fact that if the water is not accelerating and the river cross-section stays constant (generally good assumptions … See more Landscape evolution Stream power is used extensively in models of landscape evolution and river incision.
