Abstract

The article assesses natural landscape conditions for forming floods on the Alazeya river and their influence on the hydrological regime. Evaluation of the moistening mode showed that an increase in the water volume is caused by an increasing amount of precipitation. The factor determining variability of the annual river flow is precipitation in the warm period of the previous year. The degree of susceptibility of the river landscapes to various changes was assessed. Permafrost, climatic and biological indicators (ice content of surface sediments, temperature of frozen rocks, biological productivity, conditions of heat supply and moisture) were taken into account. It was determined that tundra and northern taiga lake-thermocarstic landscapes are susceptible to anthropogenic effects.
