Abstract Artificial levees along alluvial rivers are major components of flood-risk mitigation. This is especially true in the case Hungary, where more than one-third country threatened by floods and protected an over 4200-km-long levee system. Most such were built nineteenth century. Since then, several natural anthropogenic processes, as compaction erosion, might have contributed to these ear...

In this paper, a software tool developed in Matlab for stepped-frequency GPR (Ground Penetration Radar) is presented. It is intended for data simulation, image formation and basic GPR signal and image processing. The designed software can be useful for the researchers to help them analyze the performances of the different algorithms for data acquisition, signal processing and image processing. ...

Ground-penetrating radar (GPR) is a well-respected, effective, and efficient geophysical technique. However, for underwater engineering detection archaeology, the measured B-scan profiles typically contain surface-related multiple waves, which can reduce signal to noise ratio interfere with interpretation of results. SRME feedback iteration method based on wave equation, frequently utilized in ...

Methods for determining the parameters necessary for modeling fluid flow and contaminant transport in the shallow subsurface are in great demand. Soil properties such as permeability, porosity, and water retention are typically estimated through the inversion of hydrological data (e.g., measurements of capillary pressure and water saturation). However, ill-posedness and non-uniqueness commonly ...

We present the capabilities of low-frequency radar systems to sound the subsurface for a site located in south-central Egypt, the Bir Safsaf region. This site was already intensively studied since the SIR-A and SIR-B orbital radars revealed buried paleodrainage channels. Our approach is based on the coupling between two complementary radar techniques: the orbital synthetic aperture radar (SAR) ...

This is the first (Paper I) of three companion papers focused respectively, on the estimates of the errors in ice thickness retrieved from pulsed ground-penetrating radar (GPR) data, on how to estimate the errors at the grid points of an ice-thickness DEM, and on how the latter errors, plus the boundary delineation errors, affect the ice-volume estimates. We here present a comprehensive analysi...

In this paper, we adapt the Faster-RCNN framework for the detection of underground buried objects (i.e. hyperbola reflections) in B-scan ground penetrating radar (GPR) images. Due to the lack of real data for training, we propose to incorporate more simulated radargrams generated from different configurations using the gprMax toolbox. Our designed CNN is first pre-trained on the grayscale Cifar...
