Control of Sand-Hill Movements and Prevention of their Harmful Effect on Vital Infrastructures

One-third of land is covered with desert; characteristics of these areas include high temperature due to intensity of sunlight, severe winds, and low and dispersed precipitation over the year, which cause reduction of vegetation and dispersion of plants. One of the most effective causes of this little vegetation is the wind, whose impact in these areas is stronger than other lands. Severe winds affect lands by causing erosion and extreme changes, and ultimately create problems in construction and maintenance of vital facilities (roads, railways, power transmission lines, etc.).
