Stream power index value

Stream power has also been used as a criterion to determine whether a river is in a state of reshaping itself or whether it is stable. A value of unit stream power between 30 and 35 W m −2 in which this transition occurs has been found by multiple studies. See more Stream power originally derived by R. A.
