Abstract: In the era of water conservancy big data, the biggest challenge we face may not be insufficient information but information overload. The problem may not be the accessibility of information but rather the issue of isolated islands of information. Blockchain is a decentralized distributed ledger that is difficult to tamper with once the data block is confirmed to be on the chain. It is time-stamped and can avoid data islands, low data quality, and data leakage. We explore the application prospects of blockchain technology in constructing intelligent water conservancy systems and expound the risks and challenges of its applications. By combining its decentralized, non-tamperable, and traceable characteristics, the blockchain technology brings new breakthroughs to the informatization and intelligence of the water conservancy industry. It aims to break down data barriers between departments and realize co-construction and sharing of data across the industry.

Key words: blockchain, intelligent water conservancy, big data of water conservancy, co-construction and sharing of data, informatization of water conservancy
