Abstract: Water conservancy projects are numerous and widely distributed, their operation management tasks are heavy and complex.The intelligent construction of water conservancy project lags behind seriously, so it's urgent to strengthen the intelligent operation and management of water conservancy projects and maximize their comprehensive benefits.Based on the analysis of the current status and major problems of the informatization construction of water conservancy projects in China, the design of application scenarios for intelligent operation and management was analyzed.The development ideas for promoting the intelligent operation and management of water conservancy projects were proposed.Taking reservoir projects as example, the intelligent operation and management framework for water conservancy projects was proposed, which was composed of 5 layers, i.e.information perception, transmission network, cloud center, cloud service platform, and intelligent application.The study can provide reference for improving the informatization construction and enhancing the modernization management level of water conservancy projects, as well as promoting the construction of smart water conservancy.
