P1.47 Internet Technologies for Enabling Flood Emergency Early Warning Systems: the Arno River Basin Case

Flash flood early warning is a very complex activity, involving a decision-making process based on meteorological and hydrological situation description and forecasts. Anyway, the reliability of information resources is not sufficient to make a good early warning system since communication language and semantics problems arise. Indeed, the decision-makers are often not technical persons, although they can be supported by technicians, they are not scientists, or computer engineers, instead they are often politicians. This is the main reason because they could not effectively utilize available information resources data, unless they have been processed to provide highlevel integrated views, that is far from the raw dataset plotting.
