Non-destructive investigation on small earth dams using geophysical methods: Seismic surface wave multichannel analysis (masw) and s-wave refraction seismic methods
(2020-01-01)
The application of non-destructive methods of investigation in dams, such as refractive seismic analysis and multichannel surface wave analysis (MASW) are increasingly effective from the point of choosing the best dam site, ...
Detection of seepage paths in small earth dams using the self-potential method (SP)
(2020-07-01)
The application of geoelectric methods, such as induced polarization (IP), the electrical resistivity and the self-potential (SP), presents an important indirect study methodology in several areas of geology, such as mining, ...
Intensity Measure Selection for Dynamic Analysis of Earth Dams
(Oklahoma State University, 2017-06)
A comprehensive study has been developed to determine the optimal Intensity Measure to be implemented in vulnerability and quantitative risk evaluation of earth dams. Newmark analyses and nonlinear time-history evaluations ...
Análise sobre a Política Nacional de Segurança de Barragens com ênfase nos critérios de monitoramento/instrumentação
(Universidade Tecnológica Federal do ParanáGuarapuavaBrasilEngenharia CivilUTFPR, 2021-08-27)
Technological evolution has enabled the advancement of security systems in practically all areas of knowledge. Dam engineering has also absorbed these new technologies. However, dam failures still occur. Thus, knowledge ...

This paper discusses the issue of dam safety, commenting and discussing some historical dam break cases. The main types of dams are presented and the equipment used for monitoring dams. Moreover, we present a brief commentary ...
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 ...
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 ...
