Hydroinformatics is a branch of informatics qui concentrates on the implementation of information and communications technologies (ICTs) in Addressing the increasingly serious problems of the equitable and efficient use of water for Many different practical purposes. Growing out of the former discipline of computational hydraulics , the numerical simulation of water flows and related processes remains a mainstay of hydroinformatics, which encourages a focus not only on the technology and its application in a social context.
On the technical side, in addition to computational hydraulics , hydroinformatics has a strong interest in the use of so-called artificial intelligence techniques , such as artificial neural networks or recently support vector machinesand genetic programming . These might be used with a large number of data sources for the purpose of data mining , or with data generated from an existing model.
Hydroinformatics recognitions the inherently social nature of the problems of water management and decision making processes, and strives to understand the social processes. Since the problems of water management are most severe in the majority of the world, while the resources to obtain and develop the solutions are concentrated in the hands of the minority, the need to examine these social processes are particularly acute.
Hydroinformatics draws on and integrates hydraulics , hydrology , environmental engineering and many other disciplines. It sees applications in the water cycle , and in the field of water and wastewater systems. It provides support for decision making at all levels of governance and policy through management operations.
Hydroinformatics has a growing world-wide community of researchers and practitioners, and postgraduate programs in Hydroinformatics are offered by many leading institutions.  The Journal of Hydroinformatics provides a specific outlet for Hydroinformatics research,  and the community gathers to exchange ideas at the biennial conferences.  These activities are coordinated by IAHR ,  IWA ,  IAHS  Hydroinformatics Section .
There is a growing need for professionals and managers to appreciate and work with these new technologies and tools.
