This technical note presents some preliminary results obtained with the use of hydrophobic and hydrophilic
tensiometers to measure liquid pressures in three-phase systems (air-NAPL-water). The porous tips of the hydrophobic
tensiometers underwent a surface treatment known as silanization. The silanized tensiometers demonstrated l...
It is commonly accepted that the shear strength of Municipal Solid Waste (MSW) is enhanced by the
reinforcement effect of its fibrous constituents. However, most papers in the technical literature do not systematically
evaluate the effect of the MSW fibers on its stress-strain-strength response. This paper presents results of a s...
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...
After a short period of relatively intense rainfall, a deep-seated landslide occurred in a slope in Rio de Janeiro.
On the following day, field inspection revealed full saturation of the failure mass, despite the inexistence of groundwater in
the slope. A comprehensive experimental investigation was undertaken to determine the ge...
