Hydroclimatic Mapping in Geographical Atlases of the Baikal Region

This article discusses the theoretical and practical issues of hydroclimatic mapping. Hydroclimatic mapping is an important part of solving of environmental and water management problems, environmental management issues, and the adaptation of the population to climate change. Hydrological and climatic maps included in atlases of the Baikal region (Irkutsk Region: Ecological Conditions of Development (2004), Ecological Atlas of the Lake Baikal Basin (2015), and Baikal Region: Society and Nature (2021)) are presented. The authors consider the methodological approaches of hydroclimatic mapping. The limitations in using the traditional method of isolines are shown. The advantages of the basin method, landscape–hydroclimatic and structural–hydrographic approaches using zoning tools and along channel diagrams are substantiated. The article presents the methodology of flood-risk zoning, water protection, and recreational zoning of the Baikal coast and cartographic modeling of processes in the delta of the Selenga River.
