Аннотация:On the example of the small rivers of northeast Yamal features of distribution, morphology and dynamics of beaded streams are considered. It is established that the beadlike form of channels is characteristic for the rivers up to 10 km long flowing on sites with a new growth of polygonal wedge ices. Narrow channel segments of such rivers are characterized by a close bedding the permafrost whereas in the pools the permafrost lies deeply. In process of development of the beaded channel occurs a destruction of ice thresholds in narrow channel segments and the pools are filling with erosion sediments.
