Rio do Sul and Taió, in the Itajaí Valley, recorded flooding this Sunday (5). The damage occurs even on a sunny day in the two municipalities, which over the last week have had heavy rain and increased river levels.
The cities have not yet recovered from the flood situation experienced since last Friday (3), when the Itajaí-Açu River and the Itajaí do Oeste rose again.
In Taió, the river reached 10.38 meters this Sunday. The municipality is facing its fourth flood since the beginning of October. Until the last update of the text, 90 people were in a shelter opened by the city hall. In Rio do Sul, the river was at 9.49 meters early this afternoon.
The forecast is that residents will return to their homes and public cleaning will take place from Monday (6).
A Flooding on a rainless day occurs due to two factors, according to professor at the Regional University of Blumenau (Furb) and doctor in Hydrology, Ademar Cordero. The first situation is the slope of the cities, which is almost flat.
Furthermore, the capacity of the dams also interferes. The Taió and Ituporanga dams were still flowing in the morning, according to the latest update from Civil Defense. This means more water in rivers with already high levels even without rain.
