  • Summary

    A river constantly adjusts its geometry and morphology in response to the water and sediment load it receives from its watershed and to human activities, such as straightening, dredging, cutoff, levee construction, restoration, and diversion. The adjustment requires dissipation of energy. When the energy dissipation reaches a minimum rate the river tends to reach equilibrium. This chapter discusses the theory of minimum energy dissipation rate for deriving the hydraulic geometry when the river is in equilibrium state.
