Continuous ponding and shallow aquifer pumping leaches salts in clay soils

Investigation of Leaching Requirement of Continuous and Alternate Ponding Methods in Saline and Sodic Soils in South of Khouzestan Province

In this study, leaching experiments were carried out by both continuous and alternate ponding methodsin the south of Khouzestan province. In equal applied water leaching, alternate ponding leachingmodel had a better performance than continuous ponding method in desalinization and dealkalization.In term of alternate method,there was not ayn difference between 5 and 8 day periods in one-meterdept...

Mechanisms of osmotic flow and volume change in clay soils

The mechanical behavior of compressible clay soils may be strongly influenced by physicochemical effects when concentrated pore fluids are introduced to the soil. Conceptual models have been used to explain the influence of pore fluid chemistry on the mechanical behavior of clays in a qualitative way. In this paper an alternate macroscopic description of the osmotic volume change behavior of a ...
