Water is the basic natural resources and strategic economic resources. The sustainable utilization of water resources is an important guarantee for the sustainable development of economy and society. China is one of the countries with the poorest per capita water resources in the world due to the serious shortage of fresh water resources and extremely unbalanced spatial and temporal distribution. With the rapid development of economy and society and the continuous growth of population, the contradiction between supply and demand of water resources has become increasingly prominent, which has become an important constraint factor for the sustainable development of China’s economy and society.
    At present, China’s water conservancy work has entered a new period. The Party Central Committee and the State Council attach great importance to water conservancy work, regard water resources as an important strategic resource, and emphasize the sustainable utilization of water resources to support the sustainable development of society. With the deepening of the social understanding of the important position and role of water conservancy, especially the new ideas of water control proposed by the Ministry of Water Resources, water conservancy will usher in a new period of rapid development, and water conservancy infrastructure has a long way to go.
    This paper mainly introduces the main technology of water conservancy construction, as well as the management and supervision of each link in the construction process, so as to better promote the smooth construction and completion of water conservancy projects. Doing a good job in all aspects of planning and design of water conservancy projects and in risk assessment, timely supervising the progress of the whole project, doing a good job
in technical training for construction personnel, and improving the overall quality of construction workers can promote the development and progress of water conservancy project construction and lay a good foundation for the national economic development and social progress.
     In the process of writing, this book has referred to and learned from the relevant theories and research of domestic and foreign scholars, and I would like to thank you very much. Due to the lack of time, it is inevitable that there are some deficiencies in the book. Please put forward your valuable suggestions for amendment.

At present, water resources are increasingly affecting the economic and social development and the improvement of ecological environment. The total amount of water resources in China is relatively rich, but the per capita share of water resources in China is low, and the spatial and temporal distribution is uneven, which does not match the land resources and economic layout, so it is difficult to develop and utilize water resources. On the whole, it is faced with serious drought and flood disasters, prominent contradiction between supply and demand, extensive water use methods, and great pressure on water ecological environment. With the continuous growth of population, acceleration of urbanization, economic and social development, improvement of people’s living standards and global climate change, the contradictions and problems of water resources in China will continue to intensify, especially in the northern region. Due to the influence of continuous drought and human activities, the problem of water resources is more prominent.
    The problem of water resources and water environment is being paid attention to by all walks of life. Reasonable development and utilization of water resources, scientific treatment of sewage, and strengthening the management and protection of water resources have become an important means and guarantee measures for the sustainable development of human environment, economy and society. The protection of water resources and the treatment of water pollution are very important contents. Therefore, it is necessary to put the protection of water resources in a more important position. It is proposed to strengthen environmental protection, actively promote regional environmental governance of key river basins, urban sewage and garbage treatment, agricultural non-point source pollution control, comprehensive treatment of heavy metal pollution, and strengthening the development of water resources science and technology. The rational utilization and protection of water resources is not only a major strategy that must be vigorously developed and urgently promoted in our country at this stage, but also a common subject faced by human society
