Resumen de Geophysical techniques for the detection of suffusion: review of the literature

Cleber Pereira dos Santos, Jefferson de Lima Picanço

• The occurrence of tragedies by rupture of reservoirs and dams has prompted debates about the search for safer monitoring mechanisms and early detection. From this perspective, geotechnical engineering has progressively explored alternative methods to broaden the understanding of the occurrence of damage in dams. Geophysics emerges as an alternative methodology in overcoming these challenges, given its practicality in obtaining data, resolution capacity, and cost/benefit ratio, and above all by to using non-invasive methods. Thus, this research aims to present the potential of geophysical methodology in the evaluation of geotechnical problems associated with internal erosion, namely and piping in dams. To this end, a literature review was conducted about the geophysical methodologies that have successful identified piping in dam structures over the years. In addition, the theoretical aspects concerning each method will be presented, as well as the advantages and disadvantages in piping detection. Considering the versatility of the geophysical methods presented, it is believed that the increment of geophysical information in geotechnical monitoring can contribute decisively to the early detection of piping
