Особенности овражной эрозии в зоне тундры

Аннотация

Zonal geomorphologic processes have a strong effect on the gully erosion development. Within tundra zone those are thermal erosion, privation, solifluction, and thermokarst. In recent years much attention was given to thermal erosion and some progress has been made in this field, while privation and runoff redistribution caused by snow-patches were out of notice. They are not taken into consideration in the gullies development models, nor in prognostic estimations. It is privation that governs the types and subtypes of geomorphologic structure of gullies in tundra. Solifluction leads to flattening of slopes and thus forbids the gullies' growth.
