The book "Methodological recommendations for assessing the secured costs of designed hydraulic structures with an undetermined climate" is a unique work created by the team of authors, which represents an important contribution to the field of hydraulic engineering and water structures design. In the face of climate change and an increase in the frequency of extreme weather events, this publication becomes especially relevant for specialists involved in the design and operation of hydraulic facilities. The main purpose of the book is to provide methodological recommendations for the assessment of secured costs, which is a key aspect in the design of hydraulic structures. The authors examine in detail how changing climatic conditions affect hydrological parameters and, consequently, the design of such objects as dams, canals and reservoirs. In the book you will find an analysis of the various cost estimation methods, as well as practical examples that will help you better understand how to apply theoretical knowledge in real-world conditions. This book will be of interest not only to professional engineers and designers, but also to students studying in specialties related to hydraulic engineering and water resources .. Specialists working in the field of ecology and environmental protection will also find it useful information on how climate change can affect the sustainability of hydraulic structures. The book is suitable for readers aged 18 years and older who seek to deepen their knowledge in this area. The topics raised in the book cover a wide range of issues related to the assessment of risks and uncertainties arising in the design of hydraulic structures in an uncertain climate. The authors emphasize the importance of taking into account climatic factors such as temperature change, rainfall and flood frequency, which makes their recommendations especially valuable for modern projects. The book emphasizes the need to integrate scientific research and practical experience, which allows you to create more sustainable and efficient hydrotechnical solutions. The style of the authors is distinguished by clarity and accessibility of presentation, which allows readers to easily assimilate complex technical concepts. The book includes graphs, tables and diagrams that clearly illustrate the key points and make the material more understandable. This makes "Methodological Guidelines" not only a theoretical guide, but also a practical guide that can be used in everyday work. The team of authors who worked on this book consists of experienced specialists in the field of hydraulic engineering and related disciplines. Their previous works have already established themselves as reliable sources of information, and this book continues the tradition of high-quality scientific presentation. If you are interested in topics related to climate change, waterworks design or sustainable development, this edition will be a real find for you. In conclusion, “Methodological recommendations for assessing the secured costs of designed hydraulic structures with an undetermined climate” is an important resource for anyone who wants to be at the forefront in the field of hydraulic engineering design .. This book will not only help you better understand current issues, but will also provide tools to address them, making it a must-read for anyone looking for professional growth in the field.
