As intense rainfall that hit São Paulo, since last Friday (31), have punished the neighborhoods surrounding the Tietê River, such as the.
A neighborhood resident said that for more than three days several families have been island due to floods that reach the neighborhood.
Second, the original Tietê route, a meandrant river-that is, full of curves-would not allow its margins to be inhabited, because in the floodplain area of the river are large water pockets with flood areas.
“Climate change and accelerated urbanization have harmed the region, leading, in addition to flooding, other issues such as: contamination of the Sabesp distribution system and the loss of transportation capacity of the Tietê River, which already has a naturally slow flow,” explains the teacher.
A CNN Also spoke to the director of SP Águas, the São Paulo State Water Agency, linked to the State Secretariat of Environment, Infrastructure and Logistics.
“With the excess rainfall we had in a short time, the natural effect is that this water is extracted into the Várzea region, where the Jardim Pantanal neighborhood is located. This is what ends up generating this impact, ”explained director Nelson Lima.
SP Águas stated that the closure of the films of the Penha Dam has nothing to do with flooding in neighborhoods in the region.
“The population has the impression that when we close due to excess rainfall, the dam works as if it were open, which would impact the flow of that region. But Tietê already flows naturally, as there is a difference in gap 3 to 4 meters compared to the highest quota. It is flowing naturally, ”explains the director of SP Águas.
Still according to the director, the behavior is totally closed and the levels are still lowering, but the process occurs slowly.
