The physics of wind-blown sand and dust [PDF]

open access: yes, 2012
The transport of sand and dust by wind is a potent erosional force, creates sand dunes and ripples, and loads the atmosphere with suspended dust aerosols.

Study and evaluation method of concrete erosion under a wind–sand flow load

open access: yesCase Studies in Construction Materials
Many concrete buildings and infrastructures in sandstorm areas are subjected to years of sand and wind erosion. Wind erosion will damage the concrete, affect the structure durability, and even affect the safety of the structure in severe cases.

Salix gordejevii females exhibit more resistance against wind erosion than males under aeolian environment

open access: yesFrontiers in Plant Science, 2022
Effects of wind erosion on growth and adaptability have been widely reported in many plants, but little attention has been paid to dioecious plants. Recent studies have shown that sex-specific responses to environmental changes in many plants exist.

Earth-like sand fluxes on Mars [PDF]

open access: yes, 2012
Strong and sustained winds on Mars have been considered rare, on the basis of surface meteorology measurements and global circulation models, raising the question of whether the abundant dunes and evidence for wind erosion seen on the planet are a ...

Soil erosion rates caused by wind and saltating sand stresses in a wind tunnel [PDF]

open access: yes, 1993
Wind erosion tests were performed in a wind tunnel in support of the development of long-term protective barriers to cap stabilized waste sites at the Hanford Site. Controlled wind and saltating sand erosive stresses were applied to physical models of barrier surface layers to simulate worst-case eolian erosive stresses.

Effect of Different Types of Erosion on the Aerodynamic Performance of Wind Turbine Airfoils

open access: yesSustainability, 2022
Taking the S823 airfoil as the research object, this study investigates the influence of different types of leading-edge erosion on the aerodynamic performance of airfoil by using the computational fluid dynamics method.

Estimation of wind erosion rates of Mongolian Plateau by using 137Cs tracing technique

open access: yesAnnals of Warsaw University of Life Sciences - SGGW. Land Reclamation, 2010
Estimation of wind erosion rates of Mongolian Plateau by using 137Cs tracing technique Wind erosion is one of the major environmental problems in semi-arid and arid regions. Here we established a transect from northwest (Tariat, Mongolia) to southeast (Xilingol, Inner Mongolia of China) across the Mongolian Plateau, and selected eight sampling ...

Glyphosate and AMPA concentrations in wind-blown material under field conditions [PDF]

open access: yes, 2018
Agricultural intensification in fragile arid and semiarid environments has led to an increase in soil degradation, mainly through wind erosion. Argentina is an agricultural and cattle-farming country, which has increased its productivity in the last few ...

Spatiotemporal Variation in Soil Wind Erosion in the Northern Slope of the Tianshan Mountains from 2000 to 2018

open access: yesLand
The Northern Slope of the Tianshan Mountains (NSTM) is characterized by complex and diverse terrain, which represents a fragile ecological environment.

Direct numerical simulations of aeolian sand ripples

open access: yes, 2014
Aeolian sand beds exhibit regular patterns of ripples resulting from the interaction between topography and sediment transport. Their characteristics have been so far related to reptation transport caused by the impacts on the ground of grains entrained ...
