The value of such data and the need for their quick and efficient archive and analysis lead to computer-based data management, from acquisition to use in decision making (Reinstädtler et al., 2023).

Data management software is an essential key of hydroinformatics for effective water resource management.

2.5. Artificial Intelligence Tools

Artificial intelligence, such as machine learning techniques, is employed for the analysis of extensive and complex systems or datasets related to the environment. This knowledge serves as a remarkable tool in hydroinformatics, enhancing our ability to understand and manage water resources effectively.. Artificial intelligence programmes improve the use of available advances in computing by explicitly representing heuristic knowledge, providing reasoning strategies for searching this knowledge, and including explanatory facilities (to explain why a particular input is needed). These features are important for hydroinformatics because they lead to better and more informed decision making (Corzo Perez and Solomatine, 2024).

Artificial intelligence, particularly machine learning, enhances hydroinformatics by analyzing complex environmental data, improving decision-making in water resource management through advanced reasoning and explanatory capabilities.
