HYDROLOGIC-MORPHOLOGICAL ANALYSIS OF DIVIDED CHANNEL OF THE PECHORA RIVER
Abstract
Distribution of the morphodynamic types of channel is analyzed for the middle and lower courses of thePechoraRiver, a largest river of the European North, for which the channel processes were not yet studied. Channel braids of all known types, including those of 2-nd order, account for more than 80% of the river’s length. Hydrologic-morphological analysis of divided channel of thePechoraRiverwas carried out for the first time. Interrelations between the relative width of islands and branches and the flow characteristics (channel-forming and specific mean maximum water discharge) were established. Close hydrologic-morphological correlations were obtained for meanders in the branches of floodplain-channel, singular and joint braids. It was demonstrated that correlations depend on the type of braids and the order of branches, while the values of coefficients are of regional character. The branches were for the first time ever classified according to their importance into main ones (with the principal one among them) and secondary.
