River, Volume 1, Issue 1, Page 91-103, August 2022., 2022 Abstract Many slow‐moving landslides in the Three Gorges Reservoir (TGR) area exhibit episodic movement patterns in response to variations in the reservoir water level and seasonal rainfall. These landslides are typically characterized by pre‐existing shear zones composed of thick, clay‐rich layers that are sensitive to hydrological forcings.

Non-invasive (georadar) investigation of groundhog (Marmota monax) burrows, Pennsylvania, USA
Theriologia Ukrainica, 2023 Zoogenic impact plays a critical role in stream processes, especially bank stability and resulting channel dynamics. This study focuses on bioturbation by groundhogs (Marmota monax) along the riparian zone of Mill Creek (Bucks County, Pennsylvania, USA).

Application of Geodetic Techniques for Antenna Positioning in a Ground Penetrating Radar Method
E3S Web of Conferences, 2018 The accuracy of determining the location of detectable subsurface objects is related to the accuracy of the position of georadar traces in a given profile, which in turn depends on the precise assessment of the distance covered by an antenna.

Experimental tests for characterization of GPR antenna patterns
Annals of Geophysics, 1994 Detection and location of buried structures using the electromagnetic impulsive methodologies (GPR) require the study of the spatial distribution of energy irradiated by an antenna into the ground and the mechanisms of wave propagation and scattering ...

Journal of Radio Electronics, 2023 Resistive-loaded dipoles of various lengths, for different frequency ranges, are widely used in GPR suvey of subsurface ground structures. At the same time, in most cases, a transmitter with a fixed pulse length is used, which does not always allow you to fully use the characteristics of the antenna.

Assessment of Material Layers in Building Walls Using GeoRadar
Remote Sensing, 2022 Assessing the structure of a building with non-invasive methods is an important problem. One of the possible approaches is to use GeoRadar to examine wall structures by analyzing the data obtained from the scans. However, so far, the obtained data have to be assessed manually, relying on the experience of the user in interpreting GPR radargrams.

The ground-penetrating radar (GPR) method in the characterization of the Monastery of Batalha
Conservar Património, 2019 The characterization of the Monastery of Batalha included the use of the geophysical method of ground-penetrating radar (GPR), a non-destructive and indirect method that provides high-resolution 2D/3D images of the structures to investigate. Owing to the
