The full alert in Amazon, the second Amazon, which was released on Wednesday (30) by the Geological Service of Brazil (SGB), indicated a large flooding scenario in black, Salim and Amazonas in 2025.
With the expectations made 45 days before the expected peak, the survey shows a high possibility that these rivers reach the share of severe floods in several cities of the state, which affects the population of more than 2.3 million people.
In Manacaburo, for example, the Solim River has a 53 % to exceed the severity of the severe floods, estimated at 19.60 meters. In ITACOATIARA, the risk of the Amazon River reaches this same classification: 94 %, which is likely to reach about 14.57 meters.
In Manus, Rio Negro has already exceeded the flooding share (27.50 m) and could reach 28.91 meters, with a 42 % chance to reach the intense share (29 m). For Barinins, although prediction indicates a high level, the possibility of a severe flooding is low.
According to the director of hydrology and regional management of SGB in Manaus, Andrei Martinelli, the second alert data confirms the direction submitted in the first, which was released 75 days ago.
“The expectations are enhancing the perspective of expressive flood. Although it is unlikely to overcome historical records, levels must be approached or even exceeding the share of the flood,” he said.
The director of hydrology and regional administration, Alice Castelho, detailed that this year’s flood should range between 1.00 and 1.20 meters less than 2021 in Manus and Manakapuru, and up to 80 cm in Itakawakara and Parrent.
It also highlighted the effect of the last behavior of the Madeira River, which reached its climax late about 15 days, affecting the hydrological dynamics of the Amazon basin.
The expected publication event took place at the regional manager SGB, Manaus (SUNG-MA), with the participation of civil defense and climate representatives.
The aim of this is to support the preventive planning of the critical period of floods and the promotion of the institutional joint in response and mitigation procedures.
In addition to hydrological predictions, SGB operates in conjunction with the CanePam Center Management Center, the National Institute for Amazon Research (INPA) and civil and municipal departments, as well as cooperation with the institutions responsible for sanitation and assistance in weak societies.
Castilho also pointed out that SGB is participating in a group coordinated by the civil house, which also focuses on the preparations of the drought period, which succeeds in the flood in the Amazon and has specific challenges, such as water supply in isolated areas and effects on the navigation of the river.
