The book “Underground Hydraulics”, written by Isaev and Pihaev, is a fascinating and in-depth study that immerses the reader in the world of groundwater and their interaction with the environment. This is not just a scientific publication, but a real encyclopedia for those interested in hydrogeology, ecosystems and sustainable development of natural resources. From the first pages, the authors capture the attention of the reader by presenting complex concepts of hydraulics in an accessible and understandable form. They use many examples from real life, which allows not only to delve into the theory, but also to see how this knowledge is applied in practice. The book covers a wide range of topics, from groundwater physics to their role in ecosystems and effects on climate change. "Underground hydraulics" will be of interest not only to students and specialists in the field of hydrogeology, but also to a wide range of readers interested in ecology, natural resources and sustainable development. If you are a student, graduate student or just a lover of science, this book will become a real storehouse of knowledge for you. It can also attract the attention of ecologists, engineers and everyone who thinks about the future of our planet and the importance of taking care of natural resources. One of the key themes of the book is the impact of groundwater on climate and ecosystems. The authors raise important questions about how climate change affects groundwater levels and, in turn, how it affects vegetation, agriculture, and even human health. They explore how groundwater can be both a source of problems and a solution to many of the environmental challenges facing humanity. The style of Isaev and Pihaev is distinguished by clarity and logical presentation . They skillfully balance between scientific rigor and accessibility, which makes the text not only informative, but also fascinating. Their previous work is also noteworthy: for example, “Hydrogeology and Ecology” and “Sustainable Water Management” have been recognized for their in-depth analysis and practical focus. Readers who are looking for books on hydrogeology, ecology, sustainable development or just interested in natural sciences will definitely appreciate the Underground Hydraulics. This work will become not only a textbook, but also a reference book for everyone who seeks to understand the complex relationships in nature and wants to contribute to the protection of the environment. The book also raises important questions about the future of water resources and the need for their rational use. In the context of global climate change and the growing population of the planet, understanding of groundwater becomes not just relevant, but vital. "Underground hydraulics" offers the reader not only theoretical knowledge, but also practical recommendations that can be useful both in scientific activities and in everyday life. Thus, the “Underground Hydraulics” of Isaev and Pikhayev is not just a book, but a whole world of knowledge that awaits its reader. Immerse yourself in an exciting journey through the groundwater and discover their secrets that can change your perception of nature and its resources.
