A field experiment aiming to study the influence of measurement conditions on depths of penetration and resolution of GPR surveys was conducted in the middle Obra valley (western Poland). The tests were carried out along five profile lines in three sites representing fluvial, lacustrine and anthropogenic landforms. The GPR surveys were conducted at various hydrogeological conditions: high and low groundwater levels, and in winter conditions when the ground was under snow/ice cover and frozen. The best measurement conditions for imaging the internal structure of fluvial landforms were found during a period of low groundwater levels. At high groundwater levels the bottom parts of radar profiles were obscured by reverberations originating from the differences in the water content between unsaturated and saturated parts of the studied sections. Some sedimentary structures within lacustrine landforms were better seen at high levels when all the deposits were saturated. In winter conditions, high quality radar profiles were obtained only when measurements were conducted on an elevated, anthropogenic landform, unaffected by dispersion and attenuation of the radar signal in the other landforms due to a water layer situated between the ice cover and land surface. It was also shown that it is possible to image sedimentary structures of landforms built of deposits with significant admixtures of silts, although the depths of penetration are reduced in such cases.

“…Of particular usage of GPR is for geologic characterization of the subsurface materials as well as for mapping of nongeologic objects. The technique is successfully found to be applicable in stratigraphic studies of sedimentary formation (Bristow and Jol, 2003), outlining the foundation of building and other engineering structures (Abbas et al, 2009), archeological investigation (Oveisy Moakhar, 2008Negri et al, 2008), mineral exploration (Gómez-Ortiz et al, 2007;El Assel et al, 2011;Francke, 2012), location of water table, and characterization of subsurface contamination (de Menezes Travassos and de Tarso Luiz Menezes, 2004;Hamzah et al, 2009;Win et al, 2011), geomorphic studies and surface subsidence (Poole et al, 2002;Gómez-Ortiz and Martín-Crespo, 2012), and as well pipe and underground objects inspection (Mohammadi Vizheh and Kamkar Rouhani, 2013).…”

Rough Terrain GPR Antennae made of flexible hose are dragged along small trails to image near surface geology in field areas with dense vegetation and rugged topography. For accurate antenna midpoint coordinates between transmitter and receiver two miniature GPS receivers are attached to such a snake-like 50 MHz GPR antenna. During a three day field test on a Pleistocene highstand reef complex in the Dominican Republic 21 km of 2D GPR profiles were acquired. Differential post processing of the raw GPS data recorded by the two GPS rovers attached to the GPR antenna together with a third stationary GPS receiver yields sub-meter precise GPR profile coordinates on gravel roads and trails. The reef carbonates are imaged to depths of 15 m along bush trails. Data quality is degraded on gravel roads due to conductive road fill material. Overall, the network of 2D GPR profiles provides an accurate framework of the near surface geology for 3D visualization and facies correlation.
