Vulnerability of the biota in riverine and seasonally flooded habitats to damming of Amazonian rivers

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 31, Issue 5, Page 1136-1149, May 2021., 2021
Abstract The extent and intensity of impacts of multiple new dams in the Amazon basin on specific biological groups are potentially large, but still uncertain and need to be better understood. It is known that river disruption and regulation by dams may affect sediment supplies, river channel migration, floodplain dynamics, and, as a major adverse ...

Global rainfall erosivity assessment based on high-temporal resolution rainfall records [PDF]

, 2017
The exposure of the Earth’s surface to the energetic input of rainfall is one of the key factors controlling water erosion. While water erosion is identified as the most serious cause of soil degradation globally, global patterns of rainfall erosivity ...

Abordagem de discretização para modelagem de sedimentos em grande escala: estratégias de calibração baseadas na variabilidade hidrossedimentológica em múltiplas escalas espaciais [PDF]

, 2023
The lack of observed data and calibration strategies, scale variability, and difficulties in representing heterogeneity of sediment-processes contribute to the usual challenges in achieving satisfactory results in hydro-sedimentological modeling ...

Flash floods and muddy floods in Wallonia: recent temporal trends, spatial distribution and reconstruction of the hydrosedimentological fluxes using flood marks and sediment deposits [PDF]

, 2016
Flash floods and muddy floods may cause severe human and material damage despite their small spatial extent and low occurrence. In late May 2008, a major event has affected the area of Liège.

Understanding the Environmental Impact of a Mine Dam Rupture in Brazil: Prospects for Remediation

Journal of Environmental Quality, Volume 48, Issue 2, Page 439-449, March-April 2019., 2019
The rupture of the Fundão mine dam in Mariana municipality, Minas Gerais State, Brazil, spilled the tailings across the Doce River basin. These tailings, composed of residues discarded from the beneficiation of iron ore, are rich in SiO2 and Al2O3, as well as some ether amine compounds and NaOH.

Interannual variability of phytoplankton in the main rivers of the Upper Paraná River floodplain, Brazil: influence of upstream reservoirs

Brazilian Journal of Biology
The interannual variation of phytoplankton communities in the three main rivers of the Upper Paraná River floodplain is evaluated in relation to changes in the hydrosedimentological regime.

Sediment transport for nonuniform sediment mixtures: the Egiazaroff equation and its application in a canyon river in Brazil [PDF]

, 2020
Understanding the sediment yield and transport is one of the major topics of hydrosedimentology today. Although there are several methods to evaluate the incipient movement, the Shields model is mostly-used. However, the model proposed by Shields assumes
