Groundwater flow paths using combined self-potential, electrical resistivity, and induced polarization signals Open
SUMMARY The dam of Lampy (Black Mountain, Aude, France) is considered as one of the oldest dams in France. A geophysical survey is performed to better understand the pattern of groundwater flow downstream of this dam in the granitic substr…

Leakage detection applied to the Da Hedong Reservoir dam (China) based on the flow-field fitting method Open
Detecting leakage in concrete gravity dams presents a formidable challenge. The flow-field fitting (FFF) method is used to identify leaks in China’s Da Hedong Reservoir dam. We develop vertical- and horizontal-gradient approaches based on …

Combining Electrical Resistivity, Induced Polarization, and Self-Potential for a Better Detection of Ore Bodies Open
Electrical resistivity (ER), induced polarization (IP), and self-potential (SP) are three geophysical methods that have been broadly used in the realm of mineral exploration. These geophysical methods provide complementary information, eac…

Mechanism of transition between separated and non-separated oil-water flows in inclined pipe Open
The analysis of drop formation and the transition between separated and non-separated oil–water flows enables us to better regulate flow parameters and pipe inclination angle, which is of great significance for improving the efficiency of …

Flow Field Fitting Method and Acoustic Doppler Velocity Measurement: A New Approach for Detecting Leakage Pathways in Concrete‐Face Rockfill Dams Open
In this study, we aimed to detect the leakage inlets and determine the leakage pathways through a dam, and ensure that the amounts of leakage upstream and downstream are consistent and that there is no leakage around the concrete‐face rock…
