Kształtowanie koryta górskiej rzeki w warunkach aktywnych sieli (potoków gruzowo-błotnych) na jej dopływach (na przykładzie rzeki Baksan)
Influence of siels on forming a river bed and recipient's bed processes produce a direct effect on a river bed itself and influence bed's conditions, regime of water outflow and rubble. In accordance with features of a mutual influence of a river and siels tributaries the researches separated 4 basic types of run-off contact nodes in a valley of Baksan. The strongest effects of siels's influence on a river bed and recipient's longitudinal profile were recorded in contact nodes of the first
... s of the first type. Their characteristic features are torrential cones and curves of Baksan's longitudinal profile with three various sections: support, direct effects of siels's influence on a river bed and its active transformations. This type is observed in the vicinity of tributary outlets with considerably frequent siles of remarkable volume. Influence of siles from outflows on bed processes of a mountain recipient depends on valley's morphology in a section of a tributary outlet, frequency of siels's descents and their volume, regime of water outflow and recipient's rubble. Various relations between the mentioned factors lead to numerous dependences in a process of forming a recipient's bed in sections of siels tributary outlets. The mentioned dependences might be used to create models of a river bed's development after siels's descents and to prepare methods of spatial and time predictions concerning transformations of river beds in effect of siels's supply.
