On June 12, 2022, the flow of the Iguaçu Falls reached 13.7 million liters. At the time, the walkways and lookouts near the falls were banned on the Brazilian side and also on the Argentinean side.
What is water flow?
According to the Brazilian magazine of physical geography, water flow is the volume of water that passes through a given section of the river per unit of time, which is determined by the variables of depth, width and speed of the river. flow.
Water flow is commonly expressed in the international (SI) measurement system in m³/s. Discharge (flow) increases from upstream (upper river region) to downstream (downstream areas) to its mouth.

What to study about the Iguazu Falls?
Its name is derived from Tupi-Guarani, and means "big water".
They are part of the Iguaçu National Park, in the cities of Foz do Iguaçu and Puerto Iguazú.
They were formed on basaltic rocks characteristic of the Serra Geral formation, in the Paraná basin.
They are formed by 275 waterfalls, which make them the largest in the world in this regard, and are 2.7 kilometers long.
The falls vary in height from 60 to 82 meters, with the greatest difference observed in Garganta do Diabo, a postcard of the Iguaçu Falls.
The waters of the falls come from the Iguaçu River, and its average flow is 1500 m³/s.
The climate in the region is humid subtropical, marked by high air humidity and well-distributed rainfall throughout the year.
The Iguaçu National Park is home to a vast tropical forest, with remnants of the Atlantic Forest, and thousands of species of animals.
The falls are important for maintaining biodiversity and for the local economy due to tourism. Every year, more than 1.6 million people visit the region.
The falls are also culturally important, and their origin is told in Brazilian folklore.
The floods and increased flow of the Iguaçu Falls in 2022 contrast with the droughts of 2021, both causing a reduction in the number of visitors. The pandemic also caused a smaller flow of tourists.
