It is given by the equation: where Ω is the stream power, ρ is the density of water (1000 kg/m 3 ), g is acceleration due to gravity (9.8 m/s 2 ), Q is discharge (m 3 /s), and S is the channel slope.

(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 … See more Landscape evolution Stream power is used extensively in models of landscape evolution and river incision. Unit stream power is often used for this, because simple models use and evolve a 1-dimensional downstream profile of the river … See more Although many authors had suggested the use of power formulas in sediment transport in the decades preceding Bagnold's work, and in fact Bagnold himself suggested it … 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 for an averaged reach of a stream over a modest distance), all of the potential energy lost as the water flows downstream must … See more • Hydrology • Geomorphology • Erosion • Sediment transport See more WebSPI=Stream Power IndexSTI=Sediment Transport IndexCTI=Compoud Topographic Index TWI=Topographic Wetness Index（一般来说范围是-3到30，但是也有学者指出是0到30， … WebUniversity of Wisconsin - Stevens Point - University of Wisconsin ... cmeとは わかりやすく
