The book “Conditions of formation and forecasts of the natural regime of groundwater” by Vladimir Kovalevsky is a deep and fascinating study that immerses the reader in the world of hydrogeology and ecology of groundwater. This work will be a real find for students, researchers and practitioners in the field of water resources, as well as for anyone interested in natural processes and their impact on the environment. In his book, Kovalevsky examines the key aspects of groundwater formation, their dynamics and the influence of various factors on the natural regime. The author not only analyzes existing theories and models, but also offers his own forecasts based on many years of research and practical experience. The reader will be able to learn about how climate change, anthropogenic impacts and geological features affect the level and quality of groundwater. This makes the book relevant not only for professionals, but also for a wide audience interested in environmental issues and sustainable development. Who can like this work? First of all, the book will be useful for students and graduate students studying hydrogeology, ecological-geographical sciences and related disciplines . She will also be interested in practicing hydrologists, ecologists and engineers working in the field of water supply and protection of water resources. However, not only professionals will find valuable information here - the book will be interesting to those who just want to understand more deeply how the water system of our planet functions and what challenges it faces in the face of global changes. The topics raised in the book are highly relevant. Kovalevsky touches on the sustainability of ecosystems, human impact on natural resources and the need for their rational use. In the face of growing environmental problems, such as the depletion of aquifers and groundwater pollution, the author's work becomes especially important.
