Global climate warming which began in the second half of the twentieth century is continuing. Itisassociatedwithincreasedrisksfornature management, especially in permafrost areas comprising over 65% of Russia. Of special concern are hydroengineering structures located on permafrost. They are subject not only to climatic, but also to technogenic pressure caused by additional hydrothermal loads from water reservoirs. This article presents the concept of geocryological monitoring of hydroengineering structures and substantiates its necessity in view of climatic change. It also presents the methods, scope and implementation of geocryological monitoring at medium- and low-head engineering structures, considering the specific nature of Far Northern areas, as well as the complicated geotechnical, hydrogeological and permafrost conditions.
