Abstract

Use of Public Telephone Network and, in some cases, of satellite (ARGOS or METEOSAT) is of great interest for real-time hydrological data collection especially for the management of power production and distribution systems. It allows both central automatic collection of basic hydrological information - more than 400 points are already telemetered at EDF by the SCHTROUMPH system - as well as local operation of reservoirs during flood periods using an Automatic Collection Station and a micro-computer to interrogate the measurement peripheral stations. In come cases, stochastic models treating rainfall-runoff processes - but also quantitative rainfall and/or air temperatures forecasts - are used to anticipate the evolution of these parameters. Even if they need sophisticated identification techniques, these models are, now, easy to install on microcomputers. But they still remain only decision tools and they have to be disconnected from automatic operating processes.
