An Approach to Information Society Based on New Literacy of Urban Storm Phenomena

Abstract

For a long time, the word of "literacy" has been meaning human ability of reading, writing, and reckoning. Recently, however, it seems revised with the development of informatics such as computerization, communication net works and picture handling. The informatics is gradually intruding into "urban storm drainage" society, which results in : 1) a gap between dissemination of weather data and probable incidents of inundation in urban land due to heavy storm occurrence, and/or 2) an inconsistency in a concept between hypothesized hydrograph/pollutographs and real time-space control (RTSC) techniques. These contradictions may come from; 1) the lack of useful action, for citizens do not know how to use the weather data brought in by TV medium, and 2) the traditional study style stacked in statistic approaching to storm behavior, even though it is simultaneously monitored on the basis of the meso-scale meteorological information which is supplied from only the several hundreds meter high above the sea level.The new literacy will be subdivided into two phases; 1) emergence of complexity science which makes possible to deal totally with pollutographs of many quality indices, and 2) citizen's high concern to weather forecasting, the Internet utilization and so on. Therefore, the administrative specialists should alter the traditional designing of huge storm infrastructures construction in order to allow the citizens involvement into RTSC of storm storage or discharge, even in the built-up area. In this paper, a general view of rainwater and information flows of RTSC is illustrated.
