Landscape Hydrological Studies of Peak River Runoff in the South of Eastern Siberia in the Early 21st Century

The south of Eastern Siberia is a territory with contrasting natural conditions, including hydrological ones, with diverse factors of water regime formation and anthropogenic impacts on water bodies. Extreme hydrological processes whose formation is governed, in particular, by peak river runoff are typical of the region. An attention is focused on landscape hydrological and structural hydrographic research methods, analysis of the water regime formation conditions, determination of the peak river runoff parameters on the territory, and consequences of the negative impact of high river runoff on the population life. The zoning of the water-bearing capacity of the Iya River basin is carried out.
