This article introduces the hydroinformatics concept of new kinds of environments for supporting decision-making processes in the fields of water and the environment, under the name of Network Distributed Decision Support Systems (NDDSSs). These environments are designed to enable active participation of large numbers of interested stakeholders including the general public. The platforms for their development and deployment are the electronic networks such as the Internet and the wireless mobile telephony networks. Core components of such systems are instantiated hydrological models, acting as main fact providers for the participants' judgments and evaluations of the proposed courses of actions. For achieving the required performance within NDDSSs, these models need to be distributed (viz. capable of representing spatial variability as encountered in real situations) and capable of simulating integrated physical processes in the hydrological system, and open for wider integration with other kinds of models such as ecological or socioeconomic models. A brief overview of the software agent technology is presented, with its potential for the design and development of these new decision support environments. The manners in which full-fledged NDDSSs can be implemented into our present societies are also presented.
