==Hydrological Knowledge Gained==

The study of heat and moisture exchange and the water regime of small watersheds in the permafrost zone of the southern mountainous regions of Eastern Siberia (Vasilenko, Zhuravin, 1997, 1998, 1999; Vasilenko, 2004, 2013; Sokolov, Vuglinsky, 1997; Suzuki et al., 2006a,b,c; 2013; Zhang et al., 2004; Yamazaki et al., 2006), the study of the influence of deforestation on the hydrological regime (Vasilenko, 2013).

Georgiadi and Zolotokrylin (2007) showed that in the conditions of intermittent permafrost, the contribution of snow and rain to the formation of spring flooding is close to each other. Flood runoff losses are determined by the duration of snowmelt. In case of rain floods, the water output during the thawing of the permafrost is 2-3 % of the total runoff. The values of the subsurface runoff are determined.
Vasilenko (2013) developed methods for calculating the maximum flow of spring floods and rain floods in the BAM region. She proposed a comprehensive situational analysis of hydrological processes instead of factor-by-factor analysis, which takes into account the most likely combinations of natural conditions.

The use of observational data for the development of parameters of the hydrological model for the main landscape is given in the works Zhang et al. (2004), Yamazaki et al. (2006), Suzuki et al. (2013), Nesterova et al. (2018).
