[1] Estimation of the three-dimensional (3-D) distribution of hydrologic properties and related uncertainty is a key for improved predictions of hydrologic processes in the subsurface. However it is difficult to gain high-quality and high-density hydrologic information from the subsurface. In this regard a promising strategy is to use highresolution geophysical data (that are relatively sensiti...

vodeAbstractThe Radovna River Valley is located in the north-western part of Slovenia Julian Alps, where there an extensive intergranular aquifer whose depth to pre-Quaternary bedrock unknown. Therefore, obtain information about valley and geometry two geophysical methods were used our study; ground penetrating radar (GPR) seismic reflection method. The low-frequency GPR method has shown be use...

As a nondestructive geophysical tool, Ground penetrating radar (GPR) has been applied in tree root study in recent years. With increasing amounts of GPR data collected for roots, it is imperative to develop an efficient automatic recognition of roots in GPR images. However, few works have been completed on this topic because of the complexity in root recognition problem. Based on GPR datasets f...

The purposes of this study were to investigate the seasonal variations in the relative permittivity of actual concrete bridge decks of various ages on Korea expressways, and to propose a practical way to calibrate two critical effects, to assess the condition of the concrete bridge decks with better accuracy. For these purposes, fifty-three actual concrete bridge decks on Korea expressways were...

We are interested in Ground Penetrating Radar (GPR) as a geophysical tool useful for determining the depth of the ground water table (GWT) and for monitoring shallow water infiltration in sandy soils. At hydrostatic equilibrium, the water content distribution in a homogeneous unsaturated soil down to the water saturated zone depends on the soil water retention function. A classical way to fit r...

methods, intensive efforts have been undertaken to supplement the scarcity of hydrogeological data with densely We combine electromagnetic inversion of ground penetrating radar sampled geophysical data (Beres and Haeni, 1991; Ru(GPR) signals with hydrodynamic inverse modeling to identify the effective soil hydraulic properties of a sand in laboratory conditions. bin et al., 1992; Hubbard et al....

In recent years, the scale of China’s highway projects have been expanding. However, in real life, road construction some places not passed professional and rigorous inspections, resulting various quality problems, seriously affecting safety drivers pedestrians. This paper analyzes current situation engineering test detection, expounds application new technologies for detection. this paper, a c...

The Ground Penetrating Radar (GPR) has been studied for a long time as a non-destructive evaluation (NDE) technology for inspection of concrete structures. Currently, the most widely used technique for interpreting GPR data of concrete bridge decks is the one that based on the amplitudes measured at various interfaces such as asphalt-concrete, top rebar, or slab bottom. The assumption behind th...

We present an imaging pipeline to achieve enhanced images of the interior concrete from ground penetrating radar (GPR) and ultrasonic echo array (UEA) measurements. This work lays foundation for advanced yet practical tool assess structures. Specifically, we propose two-dimensional (2D) total focusing method (XTFM) reconstruct raw GPR UEA data. The proposed XTFM algorithm integrates (TFM) synth...

Quantifying the benefit of airborne and ground sensor fusion for target detection Report Title In this paper, a study involving the detection of buried objects by fusing airborne Multi-Spectral Imagery (MSI) and ground-based Ground Penetrating Radar (GPR) data is investigated. The benefit of using the airborne sensor to cue the GPR, which will then search the area indicated by the MSI, is inves...
