Abstract:

The objective of this study was to assess the efficiency of three mathematical models (power, exponential and logarithmic functions) for the calculation of the horizontal mass transport (HMT), as compared to the linear spline interpolation for the Cyclone Dust Sampler (CDS) and one with a Cone (CDSC), modified Wilson and Cooke trap (MWAC) and big spring number eight (BSNE). For the purposes of this study, wind erosion was measured at wind velocities of 2–7 ms−1 on a clay loam soil in wind tunnel experiments. The test results showed that the HMT of BSNE, MWAC, CDS, and CDSC samplers, calculated by these equations, fitted well to each other (p

Living windbreak design for wind erosion control in arid regions: A case study in Dehloran, Iran

Wind erosion is considered as one of the main processes of land degradation in different parts of the world. Among the most effective ways to control wind erosion is to cover land surface with natural vegetation area. In this study, 3 replica soil samples were collected, at a depth of 0-3 cm, from various land uses in Dehloran, Ilam Province, Iran. Physical and chemical characteristics of soil ...

The effect of mulch on properties of erosion sensitive soil using a wind tunnel

The aim of this study was to produce mulch by combining natural mineral and organic substances in order to reach soil stabilization and improve soil physical and mechanical properties in Koopal area. The effects of organic mulch (at 3 levels of O1: combination of 1% sugarcane bagasse biochar+0.5% gum Arabic+0.5% gelatin; O2: combination of 3% sugarcane bagasse biochar+1% gum Arabic+1% gelatin; ...

Wind Tunnel Experiments: Influence of Erosion and Deposition on Wind-Packing of New Snow

Wind sometimes creates a hard, wind-packed layer at the surface of a snowpack. The formation of such wind crusts was observed during wind tunnel experiments with combined SnowMicroPen and Microsoft Kinect sensors. The former provides the hardness of new and wind-packed snow and the latter spatial snow depth data in the test section. Previous experiments had shown that saltation is necessary but...

Wind tunnel experiments on the effects of tillage ridge features on wind erosion horizontal fluxes

In order to parameterize horizontal soil fluxes produced by wind over tillage ridges, eight-ridge configurations composed of sandy soil and exhibiting ridge heights to ridge spacing (RH/RS) ratios ranging from 0.18 to 0.38 were experimented in a wind tunnel. These experiments are used to develop a parameterization of the horizontal fluxes over tillage ridged surfaces based only on the geometric...

An Investigation on Performance of Shrouding a Small Wind Turbine with a Simple Ring in a Wind Tunnel

Ducted wind turbines are a kind of small wind turbine having a diffuser or any other shape around the rotor which increases the air flow through the blades and absorbs more power. In the present study, a small wind turbine was ducted with a relatively simple ring and its performance was investigated in a wind tunnel. The duct is shaped using rolling steel sheets on a sloping surface and finally...

Comparison of Interpolation Methods for the Mapping of Wind Erosion using the USEPA Model

Wind erosion is one of the environmental problems worldwide, particularly in arid and semi-arid areas of Iran. Different methods and models have been proposed to measure and monitor wind erosion in the recent years. One of the accurate models for measuring f wind erosion is the USEPA model. The purpose of this study was to evaluate the quantification of wind erosion with the USEPA model and the...
