Abstract
The research is carried out determining the role of each link of channel network in the flow formation process and the water regime features for the river systems in the Lake Baikal basin. The period of regular water flow observations is at least 30 years. The structural and hydrographic analysis of river systems made on the basis of comparison of the results of dynamic and static modeling. The dynamic model corresponds to extreme water content, the static model – on the long-time average annual flow. Provinces and intermountain zones were defining based on physical and geographical zoning. The river systems have specific characteristics of flow formation in these zones. The number of permanent, temporary and episodic river mouths flowing into the Baikal are estimated. The power (magnitude) of each elementary link of the river system is estimated. The regions of formation, transit, and accumulation of flow are defined based on the regularities of the structure of the water-erosion network. The map of the spatial and topological distribution of the river systems by flow regions is created based on the results of the research. This research is relevant for obtaining additional information in order to analyze the flow and calculate the maximum water-bearing capacity of river systems.
