Floods are natural events that cause various social and economic impacts. These events are originated from intense rainfall that exceeds soil infiltration capacity leading to major water runoff that surpasses the capacity of drainage systems. At highly urbanized basins, like the ones in São Paulo, the problem becomes even more complex since it involves land …
Real-Time Flood Forecast Modeling as a Planning Tool Leia mais »
Like other megacities São Paulo City has many infrastructure problems. One of them are the summer floods. This problem has been studied for years considering structural and non-structural measures. Many studies have shown that the investments required to reduce flooding throughout the city are very massive. This paper presents a methodology developed to the São …
São Paulo metropolitan region, like other megacities, has a high index of impervious areas which impacts its hydrology. In the summer, this region is devastated by heavy rainfall events. The main impact of this is the runoff volume produced leading to flash floods, mainly in small basins. Structural flood control measures can be costly, thus, …
Design criteria for flood control infrastructures is based on intensity duration and frequency equations (IDF), considering future scenarios of urbanization. In some situations, flood control systems do not work properly due to the lack of urban drainage planning and management. São Paulo City is an example. Its population growth was not accompanied by the urban …
This paper aims to show how the integration between weather radar and rain gages is able to improve the flooding forecast in the megacity of São Paulo. The city of São Paulo is one of the five largest cities in the world. However, this megacity has a chronic flood problem that occurs every year, especially …
This paper aims to show how the integration between weather radar and rain gages is used to improve landslide forecast in the megacity of São Paulo. The city of São Paulo is one of the biggest city in the world. However, this megacity has a chronic landslide problem that occurs every year, especially during the …
The metropolitan region of São Paulo (MRSP) has suffered from its worst drought in history, which started in 2013 and is not over yet in 2018. With 21.4 million inhabitants, the region has one of the largest water supply systems in the world, consisting of ten partially interlinked reservoir systems. Cantareira system is the largest, …
The Brazilian interconnected power system consists of a linked network of over 150 medium and large reservoirs, and a large set of small hydropower, thermal, and wind power plants. In Brazil, hydropower has been the predominant source of electrical energy supply, but the system has changed significantly over the last five years. From 2003 to …

Hydropower has been the predominant source of electrical energy supply in Brazil, with significant increasing participation share of thermal and wind power plants. From 2000 to 2012, on average, 91% of Brazilian effective electric generation was provided by hydropower, while the reservoir system operated, on average, at 68% of the active storage. From 2013 to …
