<p>A method for remediation of arid soils comprises enclosing a portion of arid soil 100 having a bottom surface 101 within embankments 102 forming a closed loop; providing in the enclosed portion at least a shading structure 103 configured to at least partly intercept and mitigate solar irradiation; waterproofing the bottom surface of the enclosed portion of arid soil and at least part of the embankments; filling the waterproofed enclosed portion of arid soil with landfill soil 107 to a predetermined height relative to the bottom surface, thereby forming a raised ground level of the enclosed portion of arid soil; supplying to the landfill soil an adjustable flow of water 111; and controlling the level reached by water relative to the waterproofed bottom surface by providing the embankments or the shading structures or both with adjustable overflow outlets for water at a depth between the bottom surface and the raised ground level.</p> |
