Geophysical investigation of earth dam using the electrical tomography resistivity technique
(Fundação Gorceix, 2017-03-01)
Abstract Dams are structures that dam rivers and streams for a variety of purposes. These structures often need to be sturdy to withstand the force of the impoundment and the high values of accumulated water load. The ...
Assessing hydrofacies and hydraulic properties of basaltic aquifers derived from geophysical logging
(Soc Brasileira Geologia, 2020-01-01)
Basaltic aquifers are an important source of water supply in many regions worldwide. Because of their cooling process, flood basalts normally have complex internal structures and unpredictable permeable zone distribution. ...
A comparison of imaging conditions for wave-equation shot-profile migration
(Soc Exploration GeophysicistsTulsaEUA, 2008)
The Brazilian Seismographic Integrated Systems (BRASIS): Infrastructure and data management
(2011-05-09)
In geophysics and seismology, raw data need to be processed to generate useful information that can be turned into knowledge by researchers. The number of sensors that are acquiring raw data is increasing rapidly. Without ...
Semiautomated geologic mapping using self-organizing maps and airborne geophysics in the Brazilian Amazon
(Soc Exploration GeophysicistsTulsaEUA, 2012)
Analysis of the Physical Integrity of Earth Dams from Electrical Resistivity Tomography (ERT) in Brazil
(2019-01-01)
Dams are structures that barrier rivers and streams for a variety of purposes. The constant maintenance of these structures is essential, since a possible accident can lead to damage of catastrophic proportions. In November ...
The use of shallow seismic reflection technique in near surface exploration of urban sites: An evaluation in the city of SãO Paulo, Brazil
(2001-12-01)
In order to evaluate the use of shallow seismic technique to delineate geological and geotechnical features up to 40 meters depth in noisy urban areas covered with asphalt pavement, five survey lines were conducted in the ...
Application of longitudinal conductance in the estimation of the natural vulnerability of the guarani aquifer system in the São Paulo stateAplicação da condutância longitudinal na estimativa da vulnerabilidade natural do sistema aquífero guarani no estado de São Paulo
(2018-01-01)
This paper presents the results obtained from geophysical data processing, which were acquired through vertical electrical soundings developed on occurrence area of the Guarani Aquifer System (GAS), in São Paulo state, ...
Piping process: Genesis and network characterization through a pedological and geophysical approach
(2020-03-01)
Piping is a soil erosion process initiated by concentrated subsurface water flow, which can develop in both natural and anthropogenic landscapes and causes various environmental impacts. The piping process acts as a relief ...
Prediction of the level of Paraguay river using neural networks.
(Pesquisa Agropecuaria Brasileira, Brasilia, v.33, p.1791-97, out.1998., 2011)
