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.
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 ...

Half of the ecoregion is in use for agriculture. About 20% is forested, mostly in deciduous trees due to the seasonal flooding. Two types of forests are associated with the Tonle Sap floodplains: a stunted swamp forest around the lake (about 10% of the area), and a short tree shrubland for the larger outlying areas. [1]
Between 11:30 and 11:40 am on 14 January 1895, whilst there was 240–260 miners underground, [note 1] a huge wall of water forced its way into the mine. [12] It is believed that fireman [note 2] William Sproston [note 3] had fired a shot into the new 10-Foot seam in Shaft No.1, [14] which weakened the barrier between the new workings and the old tunnels which were flooded with water.
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.
