Urban flood is one of the biggest environmental problems of the planet. It generates high negative impacts of various kinds: social, environmental, and economic. These problems grow exponentially in megacities, since the disorderly occupation of land, coupled with the size of the population, make it extremely complex to control and to manage. Structural measures for flood control are not enough, the city needs to deploy a number of non-structural measures such as a flood warning system. This system aims to provide real-time occurrence of floods that may cause impacts in several areas of the city. These forecasts trigger a series of actions for civil defense, firefighter, traffic control, social support, and other entities. The flood warning system of the São Paulo metropolitan region, Brazil, called SAISP system, installed a set of weather radars and telemetry networks, as well as a decision support system (DSS), which generates a set of forecasting bulletins. Several public organizations and press receive these bulletins in real time. The results obtained in the last years of operation show that SAISP is a high efficient system, bringing immense benefits to the population of the São Paulo metropolitan region. This paper presents the major technical challenges faced by SAISP in the last years of operation and shows some of their latest results, especially of the mathematical models used to forecast floods in many areas of the city. © ASCE.
