The book "Hydrology and hydraulic structures" by Smirnov G. N. and his colleagues is an indispensable work for all who are interested in water resources, their management and engineering solutions in the field of hydraulic engineering This work covers a wide range of topics related to the study of water systems, their dynamics and interaction with the environment. The book will be a useful resource for students, graduate students, engineers and anyone else who seeks to better understand hydrological processes and their impact on the construction and operation of hydraulic structures. From the first pages, the reader plunges into the world of hydrology - a science that studies the distribution, movement and properties of water on Earth. The authors elaborate on key aspects, such as the hydrological cycle, regimes of rivers, lakes and water bodies, and methods for assessing water resources. These topics are not only important for understanding the basics of hydrology, but are also relevant in light of contemporary environmental challenges such as climate change and water resource depletion. The book also pays considerable attention to hydraulic structures from simple dams and canals to complex water supply and drainage systems. The authors share their experience in the design, construction and operation of such facilities, which makes the work especially valuable for practicing engineers and designers. An important aspect is also the analysis of the impact of hydraulic structures on ecosystems, which emphasizes the need for an integrated approach to the design and operation of water bodies. Who can like this book? First of all, it will be of interest to students and teachers of technical universities studying in specialties related to hydrology, ecology and engineering . It will also attract the attention of professionals working in the field of water resources, environmental protection and urban planning. Readers interested in sustainable development and modern approaches to water management will find many useful ideas and solutions in this work. The topics raised in the book cover both theoretical aspects and practical examples, making it a universal study guide. The authors emphasize the importance of integrating knowledge from various fields: ecology, geography, engineering and economics. This allows readers to see the full picture and understand how different factors affect water resources and their use. The style of Smirnov and his colleagues is distinguished by clarity and accessibility, which makes even complex concepts understandable to a wide audience. They use a variety of illustrations, graphs and tables, which helps to visualize the information and better absorb the material. This makes the book not only a theoretical manual, but also a practical guide that can be used in the work. If you are looking for books on hydrology, hydraulic engineering or sustainable water management, Hydrology and Hydraulic Engineering will be a real find for you. This work will not only expand your knowledge, but also inspire new ideas and projects in the field of water management. Don’t miss this important work that connects theory and practice, and will help you become an expert in hydrology and hydraulic engineering.
