Stream power is the rate of potential energy loss per unit of channel length. [7] This potential energy is lost moving particles along the stream bed. = where is the stream power, is the density of water, is the gravitational acceleration, is the channel slope, and is the discharge of the stream.
In the "engineering" systems (middle column), the weight of the mass unit (pound-mass) on Earth's surface is approximately equal to the force unit (pound-force). This is convenient because one pound mass exerts one pound force due to gravity. Note, however, unlike the other systems the force unit is not equal to the mass unit multiplied by the ...
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. [1] Stream power is the result of multiplying the density of the water, the acceleration of the water due to gravity, the volume of water flowing through the river, and the ...
Units for other physical quantities are derived from this set as needed. In English Engineering Units, the pound-mass and the pound-force are distinct base units, and Newton's Second Law of Motion takes the form = where is the acceleration in ft/s 2 and g c = 32.174 lb·ft/(lbf·s 2).
River erosion in the UK. River bank failure can be caused when the gravitational forces acting on a bank exceed the forces which hold the sediment together. Failure depends on sediment type, layering, and moisture content. [1] All river banks experience erosion, but failure is dependent on the location and the rate at which erosion is occurring ...
As officials assess flood damage in the Central Coast and Central Valley, more rain moves in. Southern California will see rain Tuesday and Wednesday.
The third powerful atmospheric river storm to impact the Pacific Northwest since the end of last week blasted portions of Washington and Oregon with hurricane-force wind gusts and torrential rain ...
On "River Monsters," Jeremy Wade was forced to face one of his greatest fears. JEREMY: "Look at the size of this! I've stumbled into a potential man-eater. JEREMY: "And weighing at least 200 pounds.
