Hydroinformatics in 1999: what is to be done?

Some possible directions of future evolution of hydroinformatics as seen from the recently observed social demand point of view are indicated. Among key issues concerning water resources management, hydroinformatics can contribute by defining a coherent methodological approach for negotiation of the most relevant water-related conflicts. The latter require however equitable access of all stakeholders and parties in conflicting situations to reliable information and objective tools allowing assessment and evaluation of a family of feasible solutions. Rapidly changing Information and Communications Technologies (in particular Internet applications) will have also their impact on the way water-related industry will use the modelling software and an appropriate experience.
