Stream Power

Stream Power
Parameter Description:  Stream power is a measure of the energy of a stream channel including that which is related to the ability to transport sediment, including bedload and suspended load.
Data Type: Line (stream layer)
Field Name: STRMPOW; Common Name: Stream power
Units: watts
NetMap Module/Tool: Fluvial Processes/Network Variables
Model Description:
In NetMap a simple measure of stream power is: Ω = ρgQS
where Ω is the stream power, ρ is the density of water (1000 kg/m3), g is acceleration due to gravity (9.8 m/s2), Q is discharge (m3/s), and S is the channel slope.
