Abstract

Erosion-channel system (ECS) is defined as a complex of water streams, erosion-accumulation processes acting within basins of different order and resulting landforms. The author showed that all components of ECS have characteristic features in all their members. The functioning and self-regulation of the ECS depends on the processes in the rills, ravine thalwegs, small, middle and large rivers, i.e. formation and development of the ephemeral and perennial watercourse channels have joint base but their morphological effects turn out different. The dependences of channel parameters on their water content, runoff, sediment budget, and transport capacity were established. These dependences lie in the base of the self-regulation of whole ECS and their members.
