1. tropical soils, bentonite, hydraulic conductivity, compatibility, barriers. / CONDUTIVIDADE HIDRÁULICA E COMPATIBILIDADE EM COMBINAÇÕES DE SOLO TROPICAL E BENTONITA PARA USO EM BARREIRAS
Barriers are key elements for the environmental protection in waste disposal sites. Additionally, compacted tropical soils have great potential to be used in these barriers, once some technical matters are correctly addressed, including low hydraulic conductivity and adequate compatibility to the disposed fluids. In this context, the bentonite addition in tr

2. EVALUATION OF HYDRAULIC PROPERTIES OF UNSATURATED TROPICAL SOILS / AVALIAÇÃO DE PROPRIEDADES HIDRÁULICAS DE SOLOS TROPICAIS NÃO SATURADOS
The present research work had two main objectives. The first was to obtain a geotechnical index for measuring the weathering degree of gneissic residual soils. For that it were analyzed data corresponding to typical weathering profiles found in the municipality of Rio de Janeiro and executed a complete characterization of a specific weathering profile of fac

3. Hydraulic conductivity of compacted soils in flexible wall permeameter tests / Condutividade hidráulica de solos compactados em ensaios com permeâmetro de parede flexível
The hydraulic conductivity of five compacted soils from São Paulo state is studied aiming at their use in lining systems. Permeability tests were performed in flexible wall permeameters with constant volume hydraulic control system (closed system), rigid wall permeameters and contraction tests. It was verified that lower values of hydraulic conductivity are

4. STUDY OF THE HYDRAULIC CONDUCTIVITY OF SOILS FOR DISPOSAL OF SOLID WASTE IN THE REGION OF SANTA MARIA / ESTUDO DA CONDUTIVIDADE HIDRÁULICA DE SOLOS PARA A DISPOSIÇÃO DE RESÍDUOS SÓLIDOS NA REGIÃO DE SANTA MARIA
The study of hydraulic conductivity of soil is an important stage in the geotecnical investigations, aiming at the use of compacted soils as impermeabilizing mineral layers, for the base and cover of sanitary land-fill sites. This paper presents the study of hydraulic conductivity (k) of natural and compacted soils of the Santa Maria region, in the area call
