“…The type of transport dependent on wind and land cover as well as the size of transferred sediment was worked on in experimental conditions on research plots [28] and in wind tunnels set up in agricultural areas [30], and spaced between olive trees [29]. Using artificial conditions, the authors attempted to identify the main factors affecting changes in the soil profile considering the type and volume of material blown.…”

The article aims to present extreme aeolian processes observed in April 2011 in the fields of the Szamocin municipality in Pojezierze Wielkopolskie (the Great Poland Lakeland). Aeolian erosion of cropland was fostered by strong wind with gusts exceeding 15 m·s−1. The erosion was related to the movement of a deep barometric low from the Norwegian Sea over western Russia (Joachim barometric low). Geomorphological mapping of accumulated sandy aeolian covers was conducted. Morphometric measurements of aeolian covers were made considering their spatial distribution and the thickness of sediments that build them. Samples were collected from sediments to analyze grain size and the volume of deposited sediments was calculated. According to grain size analysis the accumulated fine-grained mineral material was well, moderately well and moderately sorted. The thickness of aeolian covers exceeded the thickness of covers presented in Polish literature so far. Calculations of the total volume of mineral sediment derived from small areas covered with aeolian erosion (a few hectares each) indicate significantly greater volumes than those provided in publications from other research areas in Poland. The described dust storms did not cause much damage in Poland. At the same time (8 April) in northern Germany, a dust storm led to a severe collision on the A19 highway. Eight people died in car accidents and dozens suffered serious injuries.

“…Soil loss during each wind simulation was estimated using the point clouds acquired by the laser scanner following the methodology proposed by Asensio et al (2016). Number of particles, size distribution, aggregates and image color histograms of eroded particles trapped by the four vertical adhesive plates were analyzed by means of an artifi cial vision camera, JAI-CM080 model (5 wind simulations and 3 observations each one: n=15).…”

A wind erosion research was carried out in a wind tunnel where sediment samples acquired were studied by an artificial vision camera. These images could be enlarged for further analysis. Image analyses were mainly colorimetry, number of particles present and their size. Soil wind erodibility was analyzed with the image analyses supported by other laboratory results. Anthrosols were the most erodible soils, whereas Calcisols showed the highest resistance to the erosive action of wind. Sediment characteristics show the influence of trap height with decreasing particle size, number and darkness as transport height increases. A two-factor ANOVA for main effect height showed that there were significant differences in particle number and size for sediments trapped 0-15 cm and 40-70 cm high. Soils could be grouped by differences in particle number and size at different heights into highly erodible Anthrosols and Leptosols, non-erodible Calcisols and Arenosols, in which fine particles were already depleted by natural wind erosion. Aggregation showed a similar pattern with decreasing values from Calcisols and Leptosols to Anthrosols and finally Arenosols, where only single sand grains were observed in adhesive traps.

“…The use of wind tunnels in the field for wind erosion studies can be difficult and expensive to deploy due to physical limitations such as site access, steepness of slopes, and labour cost required to reach and operate the tunnel (Strong et al, 2016). On‐the‐other‐hand, some newly designed portable tunnels with associated technological apparatus has been successfully used at several locations with different soil types (Asensio, Lozano, Gallardo, & Giménez, 2016; Giménez, Lozano, Torres, & Asensio, 2019).…”

Determining the effectiveness of some soil stabilizers in wind erosion prevention using wind tunnel experiments

et al. 2021

View full text Add to dashboard Cite

Laboratory wind tunnel simulations were carried out to determine the effectiveness of some soil stabilizers in reducing soil loss by wind erosion under turbulent flow conditions driven by the reference wind velocities of 9 and 11 m s−1. Particle fractions of 0.5–1 mm of two different soil types: silty clay loam (SiCL) and sandy loam (SL) were used in the experiments as erodible test surfaces after stabilizer treatments. Molasses (M), cement (Cm), a mixture of cement and molasses (Cm + M), and hydrogel (H) were applied at four different application doses, and later those materials were subjected to incubation at room temperature for 24 hr before the trays were placed in the tunnel for wind tests. During simulations under turbulent air‐flow conditions, soil losses [(qs), g m−2 min−1] were gauged for 10‐min duration immediately following the first lift‐off movement of the particles. Experimental results on qs were compared to those of two controls [untreated control (C) and water‐treated control (Cw)], which indicated that the H applications were highly effective at the doses ≥ 13.33 g m−2 for every soil type and wind velocity combination. In addition, at the application doses ≥ 13.33 g m−2, Cm and Cm + M treatments were as effective as H statistically in reducing qs at 9 m s−1 by successfully forming resistant crust layers against stronger turbulent swirls on the research test surfaces. From the point of being more easily accessible and more cost‐effective, using less expensive Cm and Cm + M treatments could be a good alternative to utilizing hydrogel in reducing wind erosion in wide field applications.
