The book "Fundamentals of engineering hydrology" by B. G. Orlova is a fascinating and in-depth study in the field of hydrology, which will become an indispensable assistant for both students and professionals working in the field of water resources, ecology and engineering. This work not only introduces the reader to the basics of hydrology, but also immerses the world of complex natural processes that affect human life and the environment. In. G. Orlov, known for his research and publications in the field of water resources, offers readers a unique perspective on engineering hydrology, combining theoretical aspects with practical examples. The book covers a wide range of topics, including the hydrological cycle, methods for calculating runoff, the impact of climate change on water resources, and more. Each section is written with clarity and accessibility, which allows even beginners in this area to quickly master the material. This book will be of particular interest to engineering students, environmentalists, and anyone interested in sustainable water management. It will be a useful resource for teachers and researchers who want to deepen their knowledge in the field of hydrology. Readers passionate about ecology, climate change and sustainable development will find in it many useful ideas and concepts that can be applied in practice. The topics raised in the book are more relevant than ever. In the face of global climate change and increasing pressure on water resources, understanding of hydrological processes is becoming critical. Orlov emphasizes the need for an integrated approach to water resources management, stressing that without a deep understanding of hydrology, it is impossible to effectively solve problems related to water supply, flood protection and ecosystem preservation. The author's style is distinguished by clarity and logical presentation, which makes complex scientific concepts available to a wide audience. In. G. Orlov not only shares his knowledge, but also inspires readers to further research in the field of hydrology His previous works, such as Hydrology and Ecology of Water Bodies and Water Resources and their Protection, have also been recognized for their scientific value and practical orientation. The book “Fundamentals of Engineering Hydrology” will become not only a textbook, but also a reference book for everyone who seeks to understand how water, as a vital resource, affects our existence. It offers readers the opportunity to look at familiar things from a new perspective, to realize the importance of water conservation and their rational use. If you are looking for literature that will help you understand the complex issues of hydrology and water resources, this book will be an excellent choice. It will not only enrich your knowledge, but also inspire active action to protect the environment. Do not miss the chance to immerse yourself in the world of engineering hydrology with B. G. Orlov and discover new horizons in understanding the water processes that shape our planet
