High-resolution aquifer analog of fluvial-aeolian sediments of the Guarani aquifer system
(2013-08-07)
The Guarani aquifer system (GAS) represents one of the biggest aquifers in the world and is the most relevant groundwater resource in South America. For the first time, by combining field and laboratory measurements, a ...
Fluvial morphology and sediment dynamics: analysis of the downstream effects of the Madeira River hydroelectric complex
(Revues Org, 2020-01-01)
Brazil has a rich density of superficial water bodies in its territory, this is associated with one of the largest potentials for hydroelectric power generation in the world. This potential has gradually been explored with ...
Dynamics of sediment transport in two subtropical plain rivers of South America
(Schweizerbart, 2006-12)
Two rivers located in the subtropical Chaco</place /> plain are compared in order to analyse the sediment transport dynamics. Gauging and sediment samples were obtained during different hydrological stages. Grain size and ...
Variabilidade temporal no transporte de sedimentos no rio Ivaí - Paraná (1977-2007)
(Sociedade Brasileira de Geologia, 2011)
This paper evaluates the behavior of suspended sediment load of the river Ivaí over a period of 32 years measured by the station further downstream the river (Novo Porto Taquara). The most suitable parameters for this ...
Rapid monitoring of heavy metals in fluvial sediments using laser-induced breakdown spectroscopy
(Sociedad Mexicana de Física, 2019-09)
In this work, a quantitative analysis of heavy metals Cr and Cu in fluvial sediments was carried out by Laser-induced breakdown Spectroscopy (LIBS) to assess the anthropogenic. To perform the analysis, different sediment ...
Determination of soluble salts in interstitial water of fluvial sediments by IE-HPLC
(Sociedad Chilena de Química, 2014)
An ionic exchange high resolution liquid chromatography (IE-HPLC) method for determination of cations and anions in interstitial water of sediments, affluent and effluent of dams is proposed in this paper.
Cations: Na+, ...
Optically stimulated luminescence and isothermal thermoluminescence dating of high sensitivity and well bleached quartz from Brazilian sediments: From Late Holocene to beyond the Quaternary?
(2016-06-01)
The development of optically stimulated luminescence (OSL) dating of sediments has led to considerable advance in the geochronology of the Quaternary. OSL dating is a well established technique to determine sediment burial ...
Sequential development of tidal ravinement surfaces in macro- to hypertidal estuaries with high volcaniclastic input: the Miocene Puerto Madryn Formation (Patagonia, Argentina)
(Springer, 2016-12)
The late Miocene beds of the Puerto Madryn Formation (Provincia del Chubut, Argentina) are formed by shallow marine and estuarine sediments. The latter include several tidal-channel infills well exposed on the cliffy coast ...

Volcaniclastic sedimentation influenced by logjam breakups? An example from the Blanco River, Chile
(Pergamon-Elsevier Science Ltd, 2020-03)
The Blanco River drains the southern flank of the Chilean Chaitén volcano toward the Pacific Ocean. During 2008, much of the rhyolitic tephra erupted by the volcano was remobilized by this (and others) fluvial system. In ...
