The Iquitos várzea (NT0128) is an ecoregion of flooded forest along rivers in Brazil, Peru and Bolivia in the west of the Amazon biome. The forest is seasonally flooded up to 7 metres (23 ft) by whitewater rivers carrying nutrient-rich sediment from the Andes. The meandering rivers often shift course, creating a complex landscape of oxbow ...
Freshwater swamp forests are a relatively understudied forest type in Southeast Asia, primarily because they are difficult to access and can harbor diseases spread by insects, such as mosquitoes. [35] In the Amazon Basin of Brazil, a seasonally flooded forest is known as a várzea, and refers to a whitewater-inundated forest.
A várzea forest is a seasonal floodplain forest inundated by whitewater rivers that occurs in the Amazon biome. [ 1 ] [ 2 ] Until the late 1970s, the definition was less clear and várzea was often used for all periodically flooded Amazonian forests.
Flooding in open pit mines leads to the so-called pit lakes, where a wide range of creatures can be seen. The flooding process happens because the drainage wells or dewatering pumps are stopped and the open spaces are filled with groundwater and surface runoff from precipitation and water bodies (e.g. rivers). Waters quality in flooded open pit ...
There are many rivers and flooded areas, but most of the vegetation is terra firme forest, not subject to flooding. [1] The ecoregion is part of the Río Negro-Juruá Moist Forests, a global ecoregion, the other parts being the Negro–Branco, Solimões–Japurá and Caquetá moist forests. The reasonably intact global ecoregion has high annual ...
Flooded grasslands and savannas is a terrestrial biome of the World Wide Fund for Nature (WWF) biogeographical system, consisting of large expanses or complexes of flooded grasslands. These areas support numerous plants and animals adapted to the unique hydrologic regimes and soil conditions .

Igapó (Portuguese pronunciation:, from Old Tupi: "root forest") is a word used in Brazil for blackwater-flooded forests in the Amazon biome. These forests and similar swamp forests are seasonally inundated with freshwater. They typically occur along the lower reaches of rivers and around freshwater lakes.
