Aeolian Remobilisation of the 2011-Cordón Caulle Tephra-Fallout Deposit: Example of an Important Process in the Life Cycle of Volcanic Ash
Dominguez, Lucia; Bonadonna, Costanza; Forte, Pablo; Jarvis, Paul Antony; Cioni, Raffaello; Mingari, Leonardo; Bran, Donaldo Eduardo; Panebianco, Juan Esteban (Frontiers Media SA, 2020-01-14)Although volcanic eruptions represent short periods in the whole history of a volcano, the large amount of loose pyroclastic material produced, combined with aeolian processes, can lead to continuous, long-lasting reworking ... -
Diseño de un túnel de viento portátil para el estudio de la erosión eólica
Colazo, Juan Cruz; Méndez, Mariano Javier; de Oro, Laura Andrea; Avecilla, Fernando; Panebianco, Juan Esteban; Buschiazzo, Daniel Eduardo (2016)La erosión eólica (EE) es un proceso de degradación irreversible de suelos de regiones áridas y semiáridas. Con el uso de túneles de viento portátiles es posible simular la EE controlando variables críticas como la velocidad ... -
Dynamics of volcanic ash remobilisation by wind through the Patagonian steppe after the eruption of Cordón Caulle, 2011
Panebianco, Juan Esteban; Mendez, Mariano Javier; Buschiazzo, Daniel Eduardo; Bran, Donaldo Eduardo; Gaitan, Juan Jose (2017)Wind erosion of freshly-deposited volcanic ash causes persistent storms, strongly affecting ecosystems and human activity. Wind erosion of the volcanic ash was measured up to 17 months after the ash deposition, at 7 sites ... -
Effect of temporal resolution of wind data on wind erosion prediction with the Revised Wind Erosion Equation (RWEQ) = Efecto de la resolución temporal de los datos de viento en la predicción de la erosión eólica con el modelo RWEQ
Panebianco, Juan Esteban; Buschiazzo, Daniel Eduardo (Asociación Argentina de la Ciencia del Suelo, 2013-12)In wind erosion modelling and assessment, wind speed is a crucial variable. Available records for large regions of the world generally show relatively low temporal resolution. The effect of using wind data of different ... -
Mass fux decay timescales of volcanic particles due to aeolian processes in the Argentinian Patagonia steppe
Dominguez, Lucia; Rossi, Eduardo; Mingari, Leonardo; Bonadonna, Costanza; Forte, Pablo Brian; Panebianco, Juan Esteban; Bran, Donaldo Eduardo (Springer Nature, 2020-09)We investigate the timescales of the horizontal mass flux decay of wind remobilised volcanic particles in Argentina, associated with the tephra-fallout deposit produced by the 2011–2012 Cordón Caulle (Chile) eruption. ... -
Meteorological conditions during dust (PM10) emission from a tilled loam soil: Identifying variables and thresholds
Avecilla, Fernando; Panebianco, Juan Esteban; Buschiazzo, Daniel Eduardo (Elsevier, 2017-10-15)Soil wind erosion and consequent PM10 emission is a complex process that has been related to surface properties and meteorological conditions. Most of the studies have emphasized on the relationship between the surface ... -
PM10 emission efficiency for agricultural soils: Comparing a wind tunnel, a dust generator, and the open-air plot
Avecilla, Fernando; Panebianco, Juan Esteban; Méndez, Mariano Javier; Buschiazzo, Daniel Eduardo (Elsevier, 2018)The PM10 emission efficiency of soils has been determined through different methods. Although these methods imply important physical differences, their outputs have never been compared. In the present study the PM10 emission ... -
PM10 emission, sandblasting efficiency and vertical entrainment during successive wind-erosion events: a wind-tunnel approach
Panebianco, Juan Esteban; Mendez, Mariano Javier; Buschiazzo, Daniel Eduardo (Springer, 2016-11)A wind-tunnel experiment was carried out to measure saltation and PM10 (particulate matter with a mean aerodynamic diameter less than 10 μ μ m) emission during three successive wind-erosion events on three different ... -
A study on the fragmentation of saltating particles along the fetch distance during wind erosion
Avecilla, Fernando; Panebianco, Juan Esteban; Buschiazzo, Daniel Eduardo (Elsevier, 2018-12)PM10 emission largely depends on the characteristics of the saltation process, which involves the movement of aggregate and isolated particles. Studies analyzing the relationship between the fragmentation of saltating ... -
A wind-tunnel study on saltation and PM10 emission from agricultural soils
Avecilla, Fernando; Panebianco, Juan Esteban; Buschiazzo, Daniel Eduardo (Elsevier, 2016-09)PM10 emission depends on the texture and the aggregation state of a soil. A decisive but less studied factor is the saltation fraction of the soil (fraction between 100 and 500 μm). Six soils of contrasting textures were ...
