Determination of River Regime Equations Based on Stream Power Equation

In this paper, river regime equations through developing of unit stream power equation and based on data of Sistan and Karaj Rivers were derived. At the first step, methods and out-comes of former researchers are classified. On the next step, based on dimensional analysis, unit stream power as a function of river flow parameters including suspended sediment load and specific gravity of particles is developed. Using the unit stream power equation and Sistan and Karaj River's data, regime equations are derived for these rivers. Finally, the results derived from regime equations are compared with the field data and regime equations of the other researchers. A good agreement was observed between field data and values resulted from developed regime equations in this research.
