Soil erosivity by wind in moderate climates

Ecological Modelling, 1994
Abstract A new computation method of the “soil erosivity” as an important and representative scalar description quantity for the steering influence of the actual or averaged regional climatic conditions on wind erosion is proposed, which is based on the combined application of two models. Erosivity describes the combined erosive action of wind stress

RWEQ – Wind erosion predictions for variable soil roughness conditions

Aeolian Research, 2016
The soil surface roughness is a main factor in all wind erosion prediction models, including the Revised Wind Erosion Equation (RWEQ). The objective of this study was to test the erodibility of two typical soils of the semiarid Argentinean Pampas under three different tillage conditions (compared to a flat surface) at three wind velocities using a wind

Biological Soil Crusts and Wind Erosion

2001
Wind is an important erosive force in deserts, where limited cover of vascular plant material offers little soil-surface protection. Dust deposition by wind often exceeds that of fluvial deposition in these drier regions (Goudie 1978; Williams et al. 1995).

Updating Soil Surface Conditions during Wind Erosion Events Using the Wind Erosion Prediction System (WEPS)

2007 Minneapolis, Minnesota, June 17-20, 2007, 2007
Abstract During significant wind erosion events the soil surface is continually modified, however, erosion models rarely account for these changes. The objectives of this work are to provide an overview of the WEPS soil surface update methodology and demonstrate that by periodic surface updating during events, a physically-based, field-scale model can ...

Soil Erosion by Wind: An Overview

1986
Wind erosion is a serious problem in many parts of the world. It physically removes the most fertile portion of the soil from the field, pollutes the air, fills road ditches, reduces seedling survival and growth, and lowers the marketability of many vegetable crops. Wind erosion also creates new desert landforms and landscapes.

Wind erosion of a soil in north Canterbury

New Zealand Journal of Experimental Agriculture, 1988
Abstract Measurements were made of soil loss from an overdrilled and heavy-rolled paddock supporting lucerne on a Glasnevin soil in north Canterbury during strong north-westerly winds on 17 and 18 April 1981. Seventy t/ha of topsoil was transported and deposited in the lee of a windbreak on the downwind side of the source paddock. Soil was deposited in

WIND EROSION MECHANICS: ABRASION OF AGGREGATED SOIL

Transactions of the ASAE, 1991
ABSTRACT The wind erosion process on agricultural soils is being modeled as the time-dependent conservation of mass transport of soil moving as saltation and creep. Emission of loose soil and abrasion of clods and crust act as sources, whereas trapping and suspension act as sinks for the moving soil. In this study, an expression for the abrasion source

Biopolymer soil stabilization for wind erosion control

2009
Laboratory experiments indicate that spray-applied biopolymer mixtures and biopolymer admixtures for compacted soil may offer cost effective means of mitigating wind-induced soil erosion. Mitigating wind-induced erosion can be a serious geotechnical consideration due to the associated soil loss and air and water quality impacts.

Crop residue removal and soil erosion by wind

Journal of Soil and Water Conservation, 2017
C rop residue, particularly corn ( Zea mays L.) residue, is often grazed by livestock or baled as animal feed or bioenergy feedstock. These practices are expected to increase to meet the increasing demands for forage and feedstock. Under irrigated, high-yield conditions, corn residue can pose some management challenges under no-till management.
