Advances in computer technology, particularly geographic information systems (GIS) and decision-support systems (DSS), have significantly improved the basis for decision making in river basin management in many countries. These tools are particularly useful for setting priorities and developing management options. However, it is important to recognize that such tools are a means to an end and complement, rather than replace, skilled well-trained managers and consultation processes. Models and decision-support tools draw on data sets in basin information management systems. GIS integrate and analyze data sets, for example ecological and environmental data, and present the results spatially. DSS look at different scenarios and show what happens when parameters are changed. These tools can be used by groups or individuals in offices, workshops or, when they can be accessed on the Internet, even at home. Another advantage of these tools is that they promote transparency.
