Stream power formula

(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 (9.8 m/s ), Q … 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 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 … 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 a decade before putting it into practice in one of his other works. It wasn't until … See more Size of displaced sediment Critical stream power can be used to determine the stream competency of a river, which is a … See more • Hydrology • Geomorphology • Erosion • Sediment transport See more WebJun 13, 2024 · Streamgaging generally involves 3 steps: 1. Measuring stream stage —obtaining a continuous record of stage—the height of the water surface at a location along a stream or river. 2. The discharge measurement —obtaining periodic measurements of discharge (the quantity of water passing a location along a stream) 3.
