Wind erosion rates on terraces in the Mackenzie Basin

Journal of the Royal Society of New Zealand, 1997
The extent of soil erosion was estimated at six transects on terraces in the Mackenzie Basin using the 137 Cs technique to quantitatively estimate erosion since 1953. Mean 137 Cs areal activity over all sites was 351±9 Bq/m 2

An expression for wind erosion rate from dry and dense soil surface

European Journal of Soil Science, 2023
Abstract Wind erosion is a physical process predominated by airborne grains rather than the wind itself. The soil deformation is either elastic–plastic or fully plastic during its collisions with solid grains, corresponding to dense and loose soils, respectively.

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

2023
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.

Accelerated Wind Erosion and Prediction of Rates

1983
When vulnerability of the soil to wind erosion is coupled with high surface winds, large-scale damage to agriculture, transportation, and human habitation can result (for example McCauley et al., 1980; Wilshire et al, 1980). The effects of off-road vehicles (ORVs) on areas of arid or semiarid soils may continue long after the ORV event if some physical

Spatiotemporal variations and driving factors of the potential wind erosion rate in the Hexi region, PR China

Land Degradation & Development, 2020
AbstractTo reduce the damage caused by wind erosion, the accurate evaluation of wind erosion dynamics and revelation of their driving mechanism are crucial. In this study, the revised wind erosion equation was applied for the estimation of the potential wind erosion rate (PWER) from 1982 to 2015 in the Hexi region, China. Geographic detection, variable

Wind erosion rate for vegetated soil cover: A prediction model based on surface shear strength

CATENA, 2020
Abstract Vegetation is regarded as the most effective measure for soil erosion control and sand control projects, which plays an important role in controlling soil wind erosion and sand disasters in arid and semiarid regions. Most of the existing models for soil wind erosion rate prediction are based on empirical results that consider factors such as

A Method for Determining Field Wind Erosion Rates from Wind-Tunnel-Derived Functions

Transactions of the ASAE, 1984
ABSTRACT THE mass flow rate equation for a convex-shaped field surface subjected to wind erosion is derived by the application of the steady state continuity equation. It is assumed and justified that the soil flow can be idealized as a flux. The resultant equation, predicted on the availability of line-intensity functions (q) developed from wind ...

High-resolution, spatially resolved quantification of wind erosion rates based on UAV images (case study: Sistan region, southeastern Iran)

Environmental Science and Pollution Research, 2022
Estimating the quantitative distribution of wind erosion rates is one of the most important requirements for managing affected environments and optimizing locations to control wind erosion. This study develops high-resolution maps for wind erosion with unmanned aerial vehicles or UAV images in the Sistan region-an area in southeastern Iran with severe ...

Comparative rates of wind and water erosion on typical farmland at the northern end of the Loess Plateau, China

Geoderma, 2019
Abstract Compound erosion of wind and water is a serious global environmental problem, and the relative magnitude of water versus wind erosion has important implications for future studies and soil conservation practices. However, currently, field measurements of compound erosion are rarely reported, probably due to the lack of generally accepted ...
