Flow rule, self-channelization and levees in unconfined granular flows [PDF]
, 2006 Unconfined granular flows along an inclined plane are investigated experimentally. During a long transient, the flow gets confined by quasistatic banks but still spreads laterally towards a well-defined asymptotic state following a nontrivial process ...

The Material Basis of 18th‐Century Meissen Porcelain
Archaeometry, EarlyView.ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Terrestrial, Atmospheric and Oceanic Sciences, 2010 The Chihsingshan Volcano Subgroup (CVSG) is one of the most important landforms located within the Tatun Volcano Group in northern Taiwan. Based on a Digital Terrain Model, contour maps and field investigations, the CVSG can be divided into four types of

ASHEE: a compressible, equilibrium-Eulerian model for volcanic ash plumes [PDF]
, 2015 A new fluid-dynamic model is developed to numerically simulate the non-equilibrium dynamics of polydisperse gas-particle mixtures forming volcanic plumes. Starting from the three-dimensional N-phase Eulerian transport equations for a mixture of gases and

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century
Fisheries Management and Ecology, EarlyView.ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Cybergeo, 2011 The valleys of the Merapi volcano are regularly filled with thick pyroclastic and volcaniclastic deposits, characterised by a large grain-size distribution, from fine ash to boulders.

Sedimentology, EarlyView.ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

The impact of volcanic eruption rate on pyroclastic hazard
Communications Earth & EnvironmentPyroclastic density currents – fast flows of hot gases, ash, and debris – are some of the most hazardous phenomena associated with explosive volcanic eruptions.

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2022 In the 90-m river bank of the middle reaches of the Icha River, thick strata of volcano-sedimentary deposits represented by pyroclastic rocks and siliceous tuffites with layers of diatomites were studied. Representative diatom assemblages assigned to the

Rheological behaviour of pyroclastic debris flow [PDF]
WIT Transactions on Engineering Sciences, 2010 The pyroclastic soils that cover the mountains of the Campania region in Italy are usually unsaturated and collapse due to rainfall infiltration triggering landslides. The evolution of these soils after collapse is not well understood. Indeed, their post-failure behaviour may be “solid-like” or “fluid-like”, depending on causes that are not well known.
