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...
The geotechnical graduate program of the University of Brasilia maintains a research site on the campus (to be
discontinued for a new place). The site is underlain by the typically partly-saturated and potentially collapsible “porous
clay” of the Federal District of Brazil. The soil conditions have been thorou...
The Brazilian road network is constructed in a highly heterogeneous geological environment and some stretches
cross through discontinuous rock masses that have uncertain or even ignored geotechnical characteristics. Rock slopes are
potentially unstable surfaces and as such are susceptible to rockfalls that affect the highway&...
