On the intermittency of sediment transport in conditions near the threshold of motion
(2015)
The dynamics of sediment particles in a
at bed channel is mainly controlled by the
coherent structures of the turbulent boundary layer, as intense velocity
uctuations
increase the instantaneous bed shear stress and ...
Sediment transport dynamics in a glacierized Andean basin: lessons from the Estero Morales, Chile
(2022)
Suspended and bedload transport dynamics on rivers draining glacierized basins depend on complex processes of runoff generation along with the degree of sediment connectivity and coupling at the basin scale. This thesis ...

Análise de metodologias para o cálculo da descarga de fundo, aplicada ao Rio Doce, ES
(Universidade Federal do Espírito SantoBRPoluição do Ar, Recursos Hídricos, Saneamento AmbientalPrograma de Pós-Graduação em Engenharia AmbientalUFES, 2012-08-17)
Knowledge of bedload transport is of primary importance in a number of aspects in watershed management, including fluvial geomorphology and ecology, stability of engineered structures and navigation condition. Despite the ...
Decrease of streamwise mean velocity of single spheres due to presence of a sparse network of immobile bed-mounted particles
(American Society of Civil Engineers, 2020)
The transport of spheres as a bed-load through a sparse network of immobile, bed-mounted submerged cylinders was experimentally studied to quantify how the mean velocity of the spheres in the streamwise direction is altered, ...
Extraordinary sediment delivery and rapid geomorphic response following the 2008–2009 eruption of Chait en Volcano, Chile
(American Geophysical Union, 2016)
The 10 day explosive phase of the 2008-2009 eruption of Chaiten volcano, Chile, draped adjacent watersheds with a few cm to >1 m of tephra. Subsequent lava-dome collapses generated pyroclastic flows that delivered additional ...
