Beaded channels of small rivers in permafrost zones

We examine the factors that are responsible for the formation of the beaded structure of channels in the permafrost zone. It is found that formation of beaded channels in the permafrost zone is possible only in the case of small gradients and water flow rates. The existence of such channels in the permafrost zone is unstable; hence, there is little likelihood that they have persisted in a relict form to date
