Abstract: The purpose of this article is to analyse the flood-warning systems through remote management to the risk of extreme hydrological events carried out by the State Institute for the Environment (INEA-RJ). The methodology involves selecting hydrological monitoring stations located in the region of the Fluminense Lowlands, Rio de Janeiro-RJ, with the observed data of the water levels of the river and rainfall. The results suggested there was a period of about 2 hours and 15 minutes from the time the river reached an 80% spillover rate until the complete overflow of the volume of water in the section monitored, in the town of Duque de Caxias-RJ-Brasil. The remote management of the rain recommended by the INEA will make it possible to broaden its range of measures for planning and response to urban risks, and in particular to provide an instant response to the civil defence of the town.
