Strength and Stiffness Parameters of an Unsaturated Tropical Soil
(Amer Soc Civil Engineers, 2018-01-01)
The interpretation of in-situ tests for site characterization of unsaturated tropical soil sites should consider both the spatial and the seasonal variability caused by the soil suction on the strength and stiffness ...
Unified approach on the interpretation of piezocone test data in a tropical soil site
(Ios Press, 2015-01-01)
The unified approach is a semi-empirical method, which incorporated the critical state soil mechanics theory for interpretation of piezocone tests. This paper discuss the applicability of this method to define stratigraphic ...
Numerical Analysis of the Behavior of Compacted and Natural Unsaturated Tropical Soils
(Ios Press, 2019-01-01)
Several regions of countries with tropical climate exhibit alternation between dry and rainy seasons and, these countries also exhibit geological processes that create ideal conditions for the formation of thick layers of ...
Experimental investigation of soil and groundwater impacts caused by vinasse disposal
(1991-12-01)
The problems caused by the residual effluents of wine distilleries for alcohol production are well known. The effluent effects in soil and groundwater are being researched in an area with sugar cane culture which receives, ...
Use of the HDS system (hydric depuration with soils) associated to other constructed wetlands techniques for public water supply
(1999-10-19)
Two projects of water treatment for public water supply were developed and operated by using combined systems of constructed wetlands. One of the projects was carried out in the town of Analandia, Sao Paulo, Brazil and ...
Fuzzy Logic and Geostatistical Techniques for Spatialization of Soil Texture in Region with Rough Terrains
(Elsevier B.V., 2011-01-01)
From the geotechnical standpoint, it is interesting to analyse the soil texture in regions with rough terrain due to its relation with the infiltration and runoff processes and, consequently, the effect on erosion processes. ...
Water table effects on bean yield and nitrate distribution in the soil profile
(2004-12-01)
In order to evaluate the bean yield under different water table levels as well as the moisture and nitrate distribution in the soil profile, a field experiment was carried out at the experimental area from the College of ...
Soil acidity, pH and aluminum management in tropical soils: the Brazilian experience
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 2004-01-01)
Temporal variability of soil CO2 emission contrasting degraded and managed pasture in Brazil
(Elsevier B.V., 2015-01-01)
Grazing areas represent the largest agricultural areas in Brazil, occupying more than 172 million hectares, about 20% of the agricultural land (IBGE, 2007). Despite the large areas of degraded pasture, little information ...
