International audience ; Sustainable groundwater management relies on data to establish resource conditions and measure the effects of management intervention. As groundwater management grows in size and complexity so does the data needed to inform it, and the systems needed to manage this data. This chapter presents a discussion of groundwater information systems, their history, and examples of their application in France and Australia, including how these systems are used to inform and improve groundwater management. Examples are presented demonstrating the application of information systems in a range of agencies and legislative settings. These examples include systems used for local management, national data standardization, online data sharing, and environmental impact assessments. Finally, lessons learned and future developments are presented. This includes a comparison of the similarities and differences in the history and current state of groundwater management system development in each country.

International audience WML2 is an international standard for the online exchange of groundwater data that addresses the problem of data heterogeneity. This problem makes groundwater data hard to find and use because the data are diversely structured and fragmented into numerous data silos. Overcoming data heterogeneity requires a common data format; however, until the development of GWML2, an appropriate international standard has been lacking. GWML2 represents key hydrogeological entities such as aquifers and water wells, as well as related measurements and groundwater flows. It is developed and tested by an international consortium of groundwater data providers from North America, Europe, and Australasia, and facilitates many forms of data exchange, information representation, and the development of online web portals and tools. ; GWML2 est une norme internationale pour l'échange en ligne de données sur les eaux souterraines qui aborde le problème de l'hétérogénéité des données. Ce problème rend les données sur les eaux souterraines difficiles à découvrir et à utiliser parce qu'elles sont structurées et fragmentées en de nombreux silos. Surmonter l'hétérogénéité des données requiert un format de données commun; cependant, jusqu'au développement de GWML2, une norme internationale appropriée faisait défaut. GWML2 représente les principales entités hydrogéologiques telles que les aquifères et les puits d'eau, ainsi que les mesures connexes et les écoulements d'eau souterraine. La norme fut développée et testée par un consortium international de fournisseurs de données sur les eaux souterraines en provenance d'Amérique du Nord, d'Europe et d'Australasie; elle facilite de nombreuses formes d'échange de données, la représentation de l'information et le développement de portails web et d'outils en ligne.
