A characterization is provided for the braidings of river channels in the North of the European territory of Russia and for the conditions of their formation. Dependencies between the parameters of branches and islands of braidings on the characteristic water discharges were obtained for the first time. It is shown that the relationship of the width of branches and the channel-forming water discharges in them is determined not only by the type of braiding but also by the status of a given branch (main, second main, secondary). The dependence of the relative width of the islands on the specific average-maximum water discharge in the ode of braiding is different for braidings of different types. On the other hand, it reflects the differences in the formation conditions for braidings of the same morphodynamical type (floodplain-channel braidings in the braided and the meandering channel). The resulting relationships between the main parameters of the bends of braided branches (radius of curvature, and pitch of bend) and the mean maximum water discharge in them are differentiated with respect to the types of braidings. The closest correlations are characteristic for the conjugated and single braids of the Pechora. The relationship of the morphometric parameters of the islands of braidings (with and length of islands) also depends on the type of braiding and river. A large scatter in the boundary values of the width and length of the island characterizes the diversity of the types of braidings on the Northern Dvina and Pechora. On the contrary, a small spread in the boundary values indicates that largely one or two types of braidings occur on the Mezen’ and Vychegda. These differences in the dependencies manifest themselves in conjunction of their general trends. The findings supplement and generalize the available evidence concerning the channel processes evolving in natural conditions and are of interest for the development of predictive assessments of channel deformations.Keywords: channel processes, rivers of the North of European Russia, morphodynamical types of channel, braidings, hydrologo-morphological dependencies.
