Because of the linear nature of water conveyance projects, they include various geological formations and are usually in contact with water. For these reasons, most constructed irrigation and drainage networks are subject to deformation and displacement due to problematic soils. One of these problematic beds is unsaturated expansive soil. Unreinforced trapezoidal canals are damaged when constructed...
The effect of quality of water on deformation, pH, EC (electrical conductivity) and osmotic suction was studied for an expansive soil during wetting and drying tests. The cyclic wetting and drying tests were conducted on samples of an expansive soil in a modified oedometer flooded with distilled, acidic and saline water. During the tests axial deformation of the samples was recorded continuously....
