This text focuses particularly on the growing interest in hydrodynamic principles of the study of underground waters, new methods of eco-based hydrogeodynamic analysis, and the estimation of the quantity of infiltration water transfer. The author also discusses aspects of mass transfer by subsurface water flow in the light of molecular kinetics, and examines a new apporach to investigating the slow movements of groundwater at the deep zones of the hydrolithosphere.

This book, with a special chapter on the problem of oil origin and the formation of hydrocarbon fields, is an in-depth study of this complex area of research. It analyzes local and regional regularities in the formation of deep fluids in petroliferous basins.

Lessons can be learnt from the past; from time to time it is useful for practitioners to look back over the historical developments of their science. Hydrogeology has developed from humble beginnings into the broad church of investigatory procedures which collectively form the modern-day hydrogeologist’s tool box. Hydrogeology remains a branch of the over-arching science of geology and today provides analysis of the sub-surface part of the water cycle within a holistic approach to problem solving. The History of Hydrogeology, is a first attempt to bring the story of the evolution of the science of hydrogeology together from a country- or region-specific viewpoint. It does not cover history to the present day, nor does it deal with all countries involved in groundwater studies, but rather takes the story for specific key countries up and until about the period 1975 to 1980. This is when hydrogeology was still evolving and developing, and in some areas doing so quite rapidly. The book has been written not only for practitioners of hydrogeology and hydrology but also for teachers and students to see the context of the evolution of the science around the globe. The History of Hydrogeology will also be of interest to science historians and all those interested in the role that individuals, institutes and nations have played over the years in defining modern day studies of groundwater.

This 1983 volume is concerned with the features of and the laws governing the occurrence of water in the interior of the Earth. Special attention is paid to the origin of the water in the interior of the Earth, its movements and its changes of state.

The Hydrological Cycle theme is a component of Encyclopedia of Water Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty Encyclopedias. The Hydrological Cycle is a process of constant water exchange or water circulation in the hydrosphere, i.e. in the system of the atmosphere - Earth's surface – soil cover - upper lithosphere (to a depth of 2000 m). Water in the hydrosphere is liquid, solid or gaseous; during the hydrological cycle it moves under the effect of heat energy, gravitation and capillary forces, converting from a liquid to its solid state or gas, and back. The hydrological cycle is one of the major geophysical processes on the planet providing relative stability of natural conditions and continuous distribution of water between ocean, land and atmosphere. The content of the Theme on The Hydrological Cycle is organized with state-of-the-art presentations covering several topics: Exchanges of Water in the Hydrosphere; Hydrosphere Components; World Water Balance; evaporation; Precipitation; Surface Water Runoff; Groundwater Hydrogeology; Glaciers and Their Significance for the Earth Nature, which are then expanded into multiple subtopics, each as a chapter. These four volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, Managers, and Decision makers and NGOs
