Abstract

The operation of flow-channel system as a natural automation is studied. There is correlation between the velocity field of flow and coarseness of channel alluvium. The morphologic features and morphometry of gigantic ridges are described. Some criticism on modem conceptions of Kunai ridges origin in the Altai mountains is given. Authors put forward the hypothesis of their formation: it is a result of "structurally self-organizing ordering of friable accumulative fluvioglacial deposits due to cryodiagenesis.
