The standard is applicable to the compilation of proposals for large and medium-sized water conservancy and hydropower projects for new construction, reconstruction and expansion. The issuance and implementation of the standard will further standardize the content and depth requirements of the project proposal preparation, and provide an important basis for the design work in the preparation stage of the water conservancy and hydropower project proposal.

"Water Conservancy and Hydropower Engineering Feasibility Study Report Compilation Regulations" (SL/T 618—2021)

It is revised on the basis of "Water Conservancy and Hydropower Engineering Feasibility Study Report Compilation Regulations" (SL 618-2013). It has 20 chapters and 2 appendices. The main technical content includes general provisions, comprehensive descriptions, hydrology, engineering geology, and engineering tasks. And scale, water-saving evaluation, project layout and buildings, mechanical and electrical and metal structures, construction organization design, construction land acquisition and resettlement, environmental impact assessment, soil and water conservation, labor safety and industrial hygiene, energy-saving evaluation, project management, project informatization , Investment estimation, economic evaluation, social stability risk analysis and conclusions and recommendations. The standard is applicable to the compilation of feasibility study reports for large and medium-sized water conservancy and hydropower projects that are newly built, rebuilt, and expanded. The issuance and implementation of the standard will further standardize the content and depth requirements of the preparation of the feasibility study report, and provide an important basis for the design work in the preparation stage of the feasibility study report of water conservancy and hydropower projects.

"Regulations for the preparation of preliminary design reports for water conservancy and hydropower projects" (SL/T 619—2021)

It is revised on the basis of "Preliminary Design Report of Water Conservancy and Hydropower Engineering" (SL 619-2013). It has 19 chapters and 2 appendices. The main technical content includes general provisions, comprehensive descriptions, hydrology, engineering geology, engineering tasks and Scale, project layout and buildings, mechanical and electrical and metal structures, fire protection design, construction organization design, construction land acquisition and resettlement, environmental protection design, water and soil conservation design, labor safety and industrial hygiene, energy saving design, project management design, project informationization , Design budget, economic evaluation and conclusions and suggestions. The standard applies to the preparation of preliminary design reports for large and medium-sized water conservancy and hydropower projects that are newly built, rebuilt, and expanded. The issuance and implementation of the standard will further standardize the content and depth requirements of the preparation of the preliminary design report, and provide an important basis for the design work in the preparation stage of the preliminary design report of water conservancy and hydropower projects.

"Guidelines for the Compilation of Flood Control Evaluation Reports for Construction Projects within the Scope of River Management" (SL/T 808—2021)

There are 9 chapters and 2 appendices. The main technical content includes basic conditions, river evolution, flood control evaluation analysis and calculation, comprehensive flood control evaluation, measures to eliminate and reduce impacts, conclusions and suggestions, etc. The standard is applicable to the compilation of flood control evaluation reports for construction projects newly built, rebuilt, and expanded within the management scope of rivers (including lakes, reservoirs, and artificial waterways). The issuance and implementation of the standard will further standardize the compilation of flood control evaluation reports for the construction of river-related projects, and provide technical support for the management and protection of rivers and lakes and the safety of flood control projects, as well as the construction of beautiful rivers and lakes.

"Table Structure and Identifier of Basic Database of Water Conservancy Objects" (SL/T 809—2021)

There are 8 chapters and 2 appendices. The main technical content includes terminology, object class identification, basic regulations, object list table, object basic information table and object relationship table, etc. The standard is applicable to the construction of the basic database of water conservancy objects and the data access related to it. The issuance and implementation of the standard will further standardize the basic database of water conservancy objects, improve the level and ability of water conservancy data management, and solve the long-standing problems of water conservancy object management and data sharing.
