Interbasin Water Exchange by Flowage in Lake Baikal

Abstract
Based on long-term data on the water balance elements of Lake Baikal, modern annual and monthly values of water exchange by flowage between the lake basins – northern, middle and southern – are calculated. It is shown that the formation of annual values of inter-basin flow is determined by the inflow of river waters into the lake. Within a year, water exchange is distributed in accordance with the seasonal course of the water balance components of the lake and its level. Taking into account the latest data on the morphometry of Baikal, the parameters of water renewal are specified both in the basins and for the entire lake. The calculated period of water renewal in the basins varies from 100 to 345 years, and for the entire lake is 320 years. The role of water exchange by flowage in the general horizontal dynamics of lake waters during the ice-free period is commensurate with the effect of storm surges, as well as with the impact of wind activity. Average flow rates initiated by water exchange by flow do not exceed 0.05 cm/s, which makes it difficult to record them with measuring instruments. However, in the zones of localization of inter-basin water flow, the average annual flow rate, according to some data, can reach 40 сm/s.
