The Andes is the longest cordillera in the world and extends from northern South America to
the southern extreme of the continent (from 11° N to 53° S). The Andes runs through seven …

An important discussion has recently called the attention of sedimentologists and
geomorphologists to the dominant fluvial styles preserved in the geological record. While …

Former hydrological studies in the Amazon Basin generally describe annual discharge
variability on the main stem. However, the downstream Amazon River only represents the …

Proposed hydropower dams at more than 350 sites throughout the Amazon require strategic
evaluation of trade-offs between the numerous ecosystem services provided by Earth's …

Patterns of surface sediment concentration distribution in rivers are significant for
understanding fluvial morphodynamics and environmental characteristics of the rivers and …

We use cosmogenic nuclide-derived denudation rates from in situ–produced 10Be in river
sediment to determine sediment production rates for the central Amazon River and its major …

Large river sediments are mostly derived from tectonically active mountain belts, but then
undergo a series of sedimentation, temporary storage and reworking episodes on their …

In this work we document and analyze the hydrological annual cycles characterized by a
rapid transition between low and high flows in the Amazonas River (Peruvian Amazon) and …

The biodiversity and productivity of the Amazon floodplain depend on nutrients and organic
matter transported with suspended sediments. Nevertheless, there are still fundamental …

Résumé The Amazon River sediment discharge has been estimated at between 600 and
1200 Mt/year, of which more than 50% comes from the Solimões River. Because of the …
