Smart water conservancy is a significant sign of high-quality development of water conservancy. Based on the natural water system, the water conservancy engineering system and water conservancy management system, it uses big data, artificial intelligence, Internet of Things, cloud computing, mobile Internet and other new generation information and communication technologies, to smart deliver the appropriate quatity and quality of water to the right place at the right time, which can support sustainable water security, high-quality water resources, livable water environment and healthy water ecology. The connotation of smart water conservancy includes six dimensions, namely goal dimension, object dimension, space-time dimension, technology dimension, value dimension and effect dimension. The goal dimension includes problem identification and governance objectives, the object dimension includes service subject and water conservancy business, the space-time dimension includes monitoring link and decision-making process, the technology dimension includes enabling system and core technology, the value dimension includes evolution model and value-added path, and the effect dimension includes functional representation and construction vision. In the development of smart water conservancy, data is the basis, so great attention should be paid to the collection, opening and sharing of water conservancy data, information is the key to intelligent water conservancy, so great attention should be paid to the information extraction and analysis from monitoring data, knowledge is the core of intelligent water conservancy, so it is necessary to strengthen the mining and upgrading of water conservancy information, and the accumulation of knowledge, intelligence and wisdom are the purpose of intelligent water conservancy, and attention should be paid to the use of artificial intelligence and the construction of standardized management system.
