, 2021 Sand dunes are coherent sedimentary structures shaped by the shear stress exerted by the overlaying fluid. Natural dunes abundantly populate deserts, river bottoms, sea beds, and even snow fields.

Modeling proppant transport and settling in a 3D propagating fracture
Deep Underground Science and Engineering, EarlyView.A versatile multiphysics tool is presented for simulating the complex processes involved in hydraulic fracturing treatments. The model couples fracture opening and propagation, variable‐density slurry flow, and proppant particle transport within the multiphysics object‐oriented simulation environment framework, based on two‐phase mixture equations and ...

Aftasten/Tantear: A sensorial, coalitional wayfinding among Muslim runners
Feminist Anthropology, EarlyView.Abstract Muslim recreational runners in Muslim‐minority settings that take up running as their preferred form of leisure indicate that they feel they have to navigate a sense of exclusion when running outdoors. This article explores the process of exploration and sensing in public, represented by the Dutch verb aftasten, to investigate the way Muslim ...

Aeolian Geomorphology of Ergs and Dunefields in Iran. [PDF]
DesertIran's geographical location causes the majority of the country to be semi-arid, arid, or hyper-arid. The existence of ergs and dunefields in the central and eastern parts of Iran has caused residential areas and all kinds of land use to be affected by ...

Size distribution and structure of Barchan dune fields [PDF]
Nonlinear Processes in Geophysics, 2011 Barchans are isolated mobile dunes often organized in large dune fields. Dune fields seem to present a characteristic dune size and spacing, which suggests a cooperative behavior based on dune interaction. In Duran et al.

Annual Review of Fluid Mechanics, 2013 An erodible bed sheared by a fluid flow, gas or liquid, is generally unstable, and bed forms grow. This review discusses the following issues, in light of the recent literature: What are the relevant dynamical mechanisms controlling the emergence of bed forms? Do they form by linear instability or nonlinear processes such as pattern coarsening?

Geological Journal, EarlyView.In this study, we re‐examine the depositional architecture of the Erfoud limestone in Morocco. Introducing new biostratigraphic constraints from chitinozoan assemblages, we show that Katian to Hirnantian bryozoan‐pelmatozoan meadows reflect flooding events linked to a series of interglacial transgressions known to have occurred immediately prior to the
