Features: This standard consists of 7 chapters, 14 sections, and 94 articles, with 3 appendices. The main technical content includes: General Provisions, Basic Data, Calculation of Design Flood Based on Flow Data, Calculation of Design Flood Based on Rainfall Data, Regional Composition of Design Flood, and Calculation of Design Flood in Arid, Karst, Glacial, Plain, and Coastal Areas, as well as the Impact of Water Conservancy and Soil and Water Conservation Measures on Design Flood. The main revisions in this edition include: expanding the scope of application vertically to the project proposal stage and the design flood review of existing engineering operation periods, and horizontally to the calculation of design flood for water conservancy and hydropower engineering design in plain river network areas, coastal, and estuarine regions; further emphasizing the scientificity, practicality, and operability of design flood calculation methods, and advocating the application of new theories and methods in practical operations; relatively weakening the requirement for reviewing basic data; expanding the relevant methods for processing flood series consistency, and including ancient floods in the category of historical floods; providing specific regulations for flood calculation during flood season and construction period; and adding the calculation of design flood in plain river network areas and design tidal level in coastal and estuarine regions.
