УСТОЙЧИВОСТЬ И ДЕФОРМАЦИИ РУСЕЛ РАВНИННЫХ РЕК

Abstract

Different morphodynamic types of river channels were distinguished on the basis of their deformation rates and degree of stability. The Makkaveyev coefficient of stability is determined by the flow hydraulic characteristics - the ratio of shear stress on the bottom to its critical value. It may serve as a criterion for distinction between incised and broad flood-plain channels and within the second type - between shifting, branching, and meandering beds.
