Floodplain Channel Morphology and Networks of the Middle Amazon River [PDF]
Water Resources Research, 2012 Floodplain channels are important components of river-floodplain systems and are known to play a key role in hydrodynamic exchange and sediment transport.

Assessment of Deforestation in the Lower Amazon Floodplain Using Historical Landsat MSS/TM Imagery
Remote Sensing of Environment, 2011 The floodplain forests bordering the Amazon River have outstanding ecological, economic, and social importance for the region. However, the original distribution of these forests is not well known, since they have suffered severe degradation since the ...

Water Resources Research, 2014 We analyzed seasonal and interannual variability in hydrological fluxes and inundation dynamics of a large floodplain unit (2440 km2) along the lower Amazon River over a period of 15 years (1995-2010).

Floodplain ecology: A novel wetland community of the Amazon
Current Biology, 2022An expedition to the upper estuarine reaches of the Amazon River reveals intriguing overlap of tropical mangrove wetlands with riverine floodplain forests. This newly discovered type of forested wetland assemblage may provide a uniquely process-rich carbon hotspot.

Water Resources Research, 2014 Modeling the routing of flood waters across large floodplains is challenging because flows respond to dynamic hydraulic controls from complex geomorphology, vegetation, and multiple water sources. In this study, we analyzed the topographic and hydrologic

Methane Emissions from the Amazon Floodplain
1997Methane (CH4) is an important greenhouse gas that also affects the chemistry and oxidation capacity of the atmosphere (Cicerone and Oremland 1988). The current burden of methane in the atmosphere is about 4700Tg (1 Tg =1 million tons) (Wahlen et al. 1989), and the global annual emission is ca. 505 Tg CH4 year−1 (Crutzen 1991). Ca.

Water level dynamics in the Amazon floodplain
Advances in Water Resources, 2003Nonlinear analysis of Amazonian River systems suggests that water level variability is due to Brownian-like motions BH. Dynamical properties of the water level is probably a response of rainfall and runoff smoothing by the stored water in the floodplain; additional inputs of water results in attenuated perturbations of the water level.

Amazon floodplain hydrology and implications for aquatic conservation
Aquatic Conservation: Marine and Freshwater Ecosystems, 2021Abstract The amplitude, duration, frequency, and predictability of runoff and inundation of aquatic habitats are key hydrological characteristics linked to aquatic ecosystem functioning and biodiversity, but they are seldom integrated into analyses of Amazon ...

Estimation of symbiotic N2 fixation in an Amazon floodplain forest
Oecologia, 2005Sustainable management for existing Amazonian forests requires an extensive knowledge about the limits of ecosystem nutrient cycles. Therefore, symbiotic nitrogen (N2) fixation of legumes was investigated in a periodically flooded forest of the central Amazon floodplain (Várzea) over two hydrological cycles (20 months) using the 15N natural abundance ...

Fishing and hunting in the Amazon floodplain
2017Billions of people rely on wild meat (wild fish and bushmeat) for their livelihood and food security, but unsustainable harvesting is causing pan-tropic defaunation. In addition to the decline of prey populations, many harvest-dependent societies in these regions are witnessing major social and environmental changes, including ...
