This paper presents a parametric study on erodibility of soils which occurs in Southern Brazil. Different
methodologies were carried out and soils more vulnerable to these phenomena were identified. The research lays mainly on
erodibility criteria based on infiltrability tests, weight loss by immersion, direct shear tests and mod...
Given the shortage of information available in the literature on transport parameters of heavy metals in Brazilian
tropical soils, the mobility of manganese (Mn2+) in a residual gneissic compacted soil is studied in this work. Manganese
can be found in toxic concentrations in landfill leachate, besides being one of the main conta...
A method based on the application of Kötter’s equation is proposed for the complete analysis of passive earth
pressure on a vertical wall retaining horizontal cohesionless backfill. The unique failure surface consisting of log spiral and
its tangent is identified on the basis of force equilibrium conditions. On...
The use of Permeable Reactive Barriers (PRBs) for in situ remediation of contaminated groundwater represents
an attractive technology for both economic and operational reasons. A reactive medium widely used in PRBs is the
Zero-Valent Iron (ZVI) which, in several case studies, has proved highly efficient for the removal of both in...
