The combination of the lignocellulosic residue sugarcane bagasse and poultry litter as carbon and nutrients sources, respectively, in organic permeable reactive barriers for remediation of metal laden acid mine drainage has not yet been extensively tested and may be promising based on chemical composition. This system is being tested in the laboratory b...
View ArticleIn the design of flexible retaining walls supported by several levels of struts, apparent design diagrams are frequently used, particularly to predict the loads on the struts. In the case of sandy soils, the traditional design diagrams do not consider water table. The present work deals with apparent design diagrams for cases considering water table. A ...
View ArticleThe influence of soil-atmosphere interactions on an unsaturated soil in water-limited environment is investigated using a coupled heat-water flow model with a balance of net solar energy at earth’s surface. The paper also presents the governing equations for soil-atmosphere interaction analysis which, although important, are still rare in geot...
View ArticleThe mining tailings disposal system is often associated to the construction of large retaining systems, either for the great volume of materials generated by industrial plants or for the impossibility or difficulty of grants for new disposal areas. Due to increasing demand, these impoundments have become much more significant, triggering considerable in...
