This book provides a general survey of Geocryology, which is the study of frozen ground called permafrost. Frozen ground is the product of cold climates as well as a variety of environmental factors. Its major characteristic is the accumulation of large quantities of ice which may exceed 90% by volume. Soil water changing to ice results in ground heaving, while thawing of this ice produces ground subsidence often accompanied by soil flowage. Permafrost is very susceptible to changes in weather and climate as well as to changes in the microenvironment. Cold weather produces contraction of the ground, resulting in cracking of the soil as well as breakup of concrete, rock, etc. Thus permafrost regions have unique landforms and processes not found in warmer lands.

The book is divided into three parts. Part 1 provides an introduction to the characteristics of permafrost. Four chapters deal with its definition and characteristics, the unique processes operating there, the factors affecting it, and its general distribution. Part 2 consists of seven chapters describing the characteristic landforms unique to these areas and the processes involved in their formation. Part 3 discusses the special problems encountered by engineers in construction projects including settlements, roads and railways, the oil and gas industry, mining, and the agricultural and forest industries.

Geocryology Stuart A. Harris — фундаментальное современное руководство по геокриологии, науке о мерзлых грунтах и процессах, протекающих в криосфере Земли. Книга подробно разбирает физические, химические и геологические аспекты формирования и существования многолетнемёрзлых пород в разных регионах планеты.

Автор анализирует условия возникновения вечной мерзлоты, её распределение, тепловой режим, криогенные процессы и влияние изменения климата на состояние криолитозоны. Особое внимание уделяется методам исследования, моделированию и практическим последствиям деградации мерзлоты для инфраструктуры и экосистем.
