Effects of Ridges on Erosion of Soil by Wind

Soil Science Society of America Journal, 1964
Abstract The effect of ridges on soil erosion by wind was studied under laboratory conditions with wind tunnels. Smoothed soil surface and 1.3, 2.5, 5.1, 10.2, and 20.3 cm. high ridges constructed of dune sand and three simulated cultivated soils were exposed to six wind velocities ranging from 47 to 83 miles per hour.

Unity of mechanisms of water and wind erosion of soils

Eurasian Soil Science, 2009
An equation for the threshold velocity of the water or wind flow at which erosion of a homogeneous model soil begins was derived on the basis of accepted and explicitly formulated suppositions and limitations and tested using experimental data. The validity of the proposed mechanisms and equations describing the lifting force of the soil-eroding water ...

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.

Soil Ridges-Clods and Wind Erosion

Transactions of the ASAE, 1984
ABSTRACT A portable wind tunnel was used to evaluate soil losses in 10 minutes from a flat surface, and from ridges 63 to 254 mm high when 0 to 60% of the soil surface was covered with nonerodible clods. Soil losses were reduced 90% with soil ridges 63 to 254 mm high, 89% with nonerodible soil clods covering 60% of the soil surface, and 98% with a ...

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).

Bentonite Stabilization of Soil to Resist Wind Erosion

Soil Science Society of America Journal, 1969
Abstract Preliminary investigations indicate that the addition of bentonite to soil followed by moistening will significantly reduce the susceptibility of the soil to wind erosion after drying. This effect persists after rupture of the aggregates originally formed through bentonite amendment provided the soil is remoistened.

A Stochastic Formulation of Soil Erosion Caused by Wind

Transactions of the ASAE, 1984
ABSTRACT DEVELOPMENT of a new equation to predict soil erosion requires the integration of the surface soil flux vector across the eroding area and for some interval of time. In this paper we analyze the time integration and show that both an arithmetic and statistical average must be considered for prediction.

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.

GLACIAL CONTROL OF WIND AND OF SOIL EROSION IN ICELAND

Annals of the Association of American Geographers, 1966
ABSTRACT Investigations near some of the icecaps of central Iceland show that pressure and winds are markedly affected by the presence of the icecaps under various synoptic conditions. The main effect is of wave formation and descent of dry air, coming predominantly from Polar or Arctic air masses, and the descent of this air is associated with a belt ...
