A hydrometeorological telemetric network for the water resources monitoring of the Athens water resource system

In the development of a decision support system (DSS) for the management of the Athens water resource system, special emphasis has been given to the real time feeding of the DSS with reliable hydrological data, using a telemetric system. This paper is concentrated on the description of this telemetric system that measures hydrometeorological variables of the river basins, and on the management of the telemetric data. The stations of the telemetric system can provide data of high reliability, without delay, and less costly than conventionally measured data. The information collected includes stage and discharge data from the main stream of each river basin, water level data of the reservoirs, rainfall and meteorological data. The data collection procedure is done periodically by the central telemetric system and all data is stored in the database for immediate use by other systems. Apart from feeding the DSS, the telemetric system will serve other purposes such as the monitoring and establishment of reliable time series of the atmospheric and water resources conditions of the area, and the supply of hydrometerological information in real time on the Internet.
