Contributions of solar-wind induced potential sputtering to the lunar surface erosion rate and it’s exosphere

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2018
Abstract Sputtering of lunar regolith by solar-wind protons and heavy ions with kinetic energies of about 1 keV/amu is an important erosive process that affects the lunar surface and exosphere. It plays an important role in changing the chemical composition and thickness of the surface layer, and in introducing material into the exosphere.

Comparative rates of wind versus water erosion from a small semiarid watershed in southern Arizona, USA

Aeolian Research, 2011
The relative erosion rates of wind and water erosion have rarely been studied simultaneously and are poorly quantified. In this study, wind and water erosion rates were simultaneously measured and compared over 2 yrs for a small rangeland watershed in the Santa Rita Experimental Range in southern Arizona.

The fractionation of soil aggregates associated with primary particles influencing wind erosion rates in arid to semiarid environments

Geoderma, 2019
Abstract Soil particle size distribution (PSD) plays an important role in wind erosion studies and sediment transport modeling. Few studies have been done focusing on the susceptibility of different soil fractions to wind erosion under natural conditions.

Using 137Cs tracing technique to estimate wind erosion rates in the typical steppe region, northern Mongolian Plateau

Science Bulletin, 2008
Wind erosion is one of the major factors of land degradation in the typical steppe region, northern Mongolian Plateau. Using 137Cs tracing technique, we estimated the wind erosion rates of different pastures and abandoned farmland at Bayannur and Karakorum in Mongolia.

Large‐scale variability of wind erosion mass flux rates at Owens Lake: 1. Vertical profiles of horizontal mass fluxes of wind‐eroded particles with diameter greater than 50 μm

Journal of Geophysical Research: Atmospheres, 1997
A field experiment at Owens (dry) Lake, California, tested whether and how the relative profiles of airborne horizontal mass fluxes for >50‐μm wind‐eroded particles changed with friction velocity. The horizontal mass flux at almost all measured heights increased proportionally to the cube of friction velocity above an apparent threshold friction ...

Comparison of soil erosion rates by wind and water in a semi-arid loess soil 

Soil erosion is a significant process in the loss of soil/land resources, degradation and desertification. Traditionally, wind and water erosions have been studied and modelled separately. A quantitative sediment flux measure from a specific soil due to both water and wind erosion is lacking.

NON-LINEAR MODELLING TO DESCRIBE THE WIND EROSION RATE IN DIFFERENT TILLAGE PRACTICES

2018
Soil erosion is a growing problem in Turkey and particularly in the Middle Anatolia, the biggest semi arid agricultural production area with great agricultural activity. Soil erosion not only decreases agricultural productivity, but also reduces the water availability in region. Nonlinear regression models are important tools because many crop and soil

Wind erosion rates in the Arctic as recorded the roots of tundra shrubs  – a new dendrochronological approach

Arctic and sub-Arctic terrestrial environments often have bare surfaces, thin and poorly developed soils, large amounts of loose sediment, and low and sparse vegetation. The sensitivity of these sites to modern climate change is reflected, among other things, in an increase in the activity of erosion processes mainly via deflation.
