The book "Hydrotechnical anti-erosion structures" by Stepanov P. It is a fascinating and informative publication that immerses the reader in the world of hydraulic engineering and its importance for the protection of the environment. In the context of global climate change and active human intervention in nature, this work becomes especially relevant, raising important questions about the conservation of natural resources and sustainable development. Stepanov, as an experienced engineer and researcher, shares his knowledge and practical experience in the design and operation of structures aimed at preventing soil erosion. The book covers a wide range of topics, ranging from the theoretical foundations of hydrology to practical recommendations for the construction and maintenance of anti-erosion structures. The reader will be able to learn about the different types of structures, their purpose and principles of operation, as well as about modern technologies used in this field. This edition will be of particular interest to students and professionals in the fields of civil engineering, ecology and environmental management, as well as to all those interested in sustainable development and environmental protection. The book is suitable for both beginners and experienced professionals who want to deepen their knowledge and expand horizons in the field of hydraulic structures. The topics raised in the book go beyond purely technical aspects. Stepanov emphasizes the importance of an integrated approach to solving erosion problems, emphasizing the need for interaction between various branches of science and practice. It considers the influence of human activity on natural processes and suggests ways to minimize them. In this context, the book becomes not only a textbook, but also a real manifesto for those who strive for harmony between man and nature. Stepanov's style is distinguished by clarity and accessibility, which allows the reader to easily assimilate even the most complex concepts. His previous works, such as Fundamentals of Hydrology and Environmental Aspects of Hydrotechnical Engineering, have already established themselves as reliable sources of information for students and practitioners. In Hydrotechnical Anti-Erosion Facilities, the author continues his tradition of sharing knowledge, making it available to a wide audience. The book also includes many illustrations, diagrams and examples from practice, which makes it not only informative, but also visually attractive. The reader will be able to see how theoretical knowledge is applied in practice, which greatly enriches the perception of the material. An important aspect is also the presence of sections devoted to the analysis of the effectiveness of various structures and methods of their construction, which makes the book useful for practicing engineers and designers. If you are looking for literature that will help you understand how to protect nature and use hydraulic structures to prevent erosion, then “Hydrotechnical anti-erosion structures” will become an indispensable assistant. This book will not only expand your knowledge, but also inspire new ideas and projects aimed at preserving the environment. Thus, “Hydrotechnical anti-erosion structures” is not just a book, but a whole world in which everyone who is interested in ecology, construction and sustainable development should immerse themselves. Stepanov offers readers a unique opportunity to look at the problems faced by modern society and find ways to solve them through the prism of science and practice.
