Coupling sediment supply from hillslope hydrology and fluvial morphodynamics at tropical mountain basins
(Universidad Nacional de ColombiaMedellín - Minas - Doctorado en Ingeniería - Recursos HidráulicosDepartamento de Geociencias y Medo AmbienteFacultad de MinasMedellínUniversidad Nacional de Colombia - Sede Medellín, 2022)
Mountain basins are open dynamic systems which organize at multiple scales to transform
hillslope sediment supply to fluvial sediment transport. In a given river reach, its
form and sediment regime depend on basin processes ...
Colluvial deposits as a possible weathering reservoir in uplifting mountains
(European Geosciences Union, 2018)
The role of mountain uplift in the evolution of the global climate over geological times is controversial. At the heart of this debate is the capacity of rapid denudation to drive silicate weathering, which consumes CO2. ...
Interações geomorfológicas entre bacias de cabeceira e vales fluviais principais: abordagem multiescalar na Bacia do Ribeirão Mata Porcos, Quadrilátero Ferrífero-MG
(Universidade Federal de Minas GeraisUFMG, 2014-06-04)
The Geomorphology, as interdisciplinary and multi-scale knowledge body, demonstrates that these approaches are possible and even desirable in Science. Thus, I present this work which has the general aim of testing the ...

The Cerro Guanaco mass movements: A geophysical and morphometric approach on a megalandslide in the Fuegian Andes (Southern Patagonia)
(Pergamon-Elsevier Science Ltd, 2020-08)
The Fuegian Andes, in the southernmost part of South America, are characterized by a relatively young deglacial landscape, where the glacial erosive relief is strongly influenced by regional-scale geological structures, ...
Relationships between landform properties and vegetation patterns in the Cerro Zonda Mt., Central Precordillera of San Juan. Argentina
(Pergamon-Elsevier Science Ltd, 2019-09)
Arid environments are dynamic systems due, in part, to the action of hydrological processes. However, studies on the relationship between the abiotic factors and the properties of arid vegetation communities of Argentina ...
Caracterização pedológica, uso da terra e modelagem da perda de solo em áreas de encosta do rebordo do planalto do RS
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2010-02-25)
The river catchment Vacacaí Mirim is located where the water reservoir that supplies part of the water needs of the city of Santa Maria is located in a hillslope area of
plateau border Southern Rio Grande. In these hillslope ...
Geochronological and paleoenvironmental reconstruction of colluvial deposits in a cuesta landscape in south-eastern Brazil
(2022-04-01)
The classic models of cuesta evolution in south-eastern Brazil have temporal gaps in their denudation chronology. Here, we analyzed the colluvial deposits located on the rim of the Serra Geral escarpments in the Paraná ...
