Abstract
WIND EROSION OF SOIL IN A BASIN WADI AL-HAWAIMI IN THE DESERT OF NAJAF
The size distribution is an indication of the extent to which the soil
is affected and its susceptibility to wind erosion, and the clusters
with diameters less than (0.84 m) are among the most affected by
wind erosion. In other words, the soil loss by wind erosion
decreases with the increase in the size distribution of minutes and
according to the following order: (clay 'silt, sand Which means that
the sandy soil particles are less coherent than the clay soil particles,
so soil aggregates with a high sand ratio are prone to separating
more quickly than those with high clay content and thus have less
resistance to wind erosion, unlike the clay agglomerations most
affected by wind erosion. In other words, wind erosion of soil
increases in sandy tissue soils, and the study reached the following
results :
-Wind erosion of soil increases in sandy textured soils if it ranges
between (121 - 331) Mg, H - 1.
As for the muddy sand textured, the values of the soil erosibility
index decreased to (5 - 75) μg, H-1.
-The results confirmed that the highest value of the soil erosibility
index was in soils with low moisture content and ranged between
(221.3 - 331.2) Mg, HAs for soils with low content of organic matter, it led to a high index
of soil erosion vulnerability.
-The highest value of the soil erosibility index was in soils, the
higher the calcium carbonate content.
