Ground penetrating radar (GPR) was used to non-invasively map the location of unmarkedgraves within the Lake Condah Mission Cemetery in western Victoria as a means of siting future interments. This cemetery was associated with the former Lake Condah Mission (established in 1869) and continues to be an important site for local Indigenous people. It is anecdotally thought to contain more than 100 graves however only 26 are currently marked. The GPR survey identified an additional 14 probable unmarked graves as well as 49 other areas that may contain one or more unmarked burials. The extensive subsurface disturbance present at the site and the presence of many extant tree roots made the effective interpretation of the GPR data difficult. Despite this, it was still possible to delineate areas where no unmarked graves are present. This is an important outcome for managing the cultural heritage of the cemetery because it identifies areas where new graves can be emplaced in a culturally appropriate fashion. This demonstrates the utility of GPR as a means of effectively managing heritage sites containing unmarked graves, even when substantial subsurface disturbance is present.

Moisture damage is the most critical issue regarding the preservation and integrity of cultural heritage sites. The electromagnetic (EM) sensitivity to the presence of moisture, in both soils and structural materials, is a well-known phenomenon. Thereby, studying the EM response to the presence of moisture, in order to prevent the damages done to sites of cultural heritage, is a well-established method. This paper will discuss the ability of a geophysical non-destructive technique (NDT), present in a Ground Penetrating Radar (GPR) system, to investigate a very precious building in Rome that is affected by a moisture problem (the Turkish Room at Villa Medici). This geophysical instrument is able to locate and estimate the extent of water ingression, which can aid in the development of restoration plans before permanent damage occurs. The main objective of this paper is to help restorers understand the related hazards, due to the presence of moisture in the wall structures, in real-time and to rapidly and non-invasively develop strategies for the preservation of cultural heritage sites.

The Given

Abstract The paper is devoted to using ground penetrating radar (GPR) for the detection of tree roots in an urban area, since GPR allow detect the hidden objects in non invasive way. It is necessary exactly to know the growth direction, thickness and depth of the roots of the tree to confidently assert about the tree root influence on the technical condition of engineering objects and structures: of the buildings, of pavements, of roadway, of engineering communications and etc. The aim of the given research was experimentally to evaluation the possibilities of detection of tree roots in an urban area with the use of GPR on frequency 400 MHz and of algorithms of secondary processing of GPR signals. Results of interpretation of radar profile and evacuation of soil around tree show the possibility of detection of the tree roots and the determination of their parameters using one or two radar concentric profiles.

Inversion Techniques

Ground Penetrating Radar (GPR) systems arenowadays standard inspection tools in several application areas, such as subsurface prospecting, civil engineering and cultural heritage monitoring. Usually, the raw output of GPR isprovided as a B-scan, which has to be further processed inorder to extract the needed information about the inspectedscene. In this framework, inversescattering-based approachesare gaining an ever-increasing interest, thanks to their capabil-ities of directly providing images of the physical and dielectricproperties of the investigated areas. In this paper, some advances in the development of such inversion techniques in theGPR field are revised and discussed.

Ground Penetrating

Protection and conservation are not feasible without a deeper knowledge of the cultural heritage of the subject of intervention. A careful analysis of documentation, a detailed visual inspection of surfaces, and a systematic diagnosis of the inner properties are the basis for planning preventive strategies of restoration. Digital noninvasive techniques represent an advantageous tool with useful outputs to estimate the state of health of cultural heritage in order to minimize the progress of degradation. This paper deals with a 3D metric survey through photogrammetry and ground-penetrating radar (GPR) tests applied to the study of the trapezophoros with two griffins attacking a doe of Ascoli Satriano, a masterpiece of ancient art that needs to be protected. This work provided information on both visible and hidden defects, such as numerous cracks that affect the sculpture.

The application of biochar amendments to soil has been proposed as a strategy for mitigating global carbon (C) emissions and soil organic carbon (SOC) loss. Biochar can provide additional agronomic benefits to cropping systems, including improved crop yield, soil water holding capacity, seed germination, cation exchange capacity (CEC), and soil pH. To maximize the beneficial effects of biochar amendments towards the inventory, increase, and management of SOC pools, nondestructive analytical methods such as ground penetrating radar (GPR) are needed to identify and quantify belowground C. The use of GPR has been well characterized across geological, archaeological, engineering, and military applications. While GPR has been predominantly utilized to detect relatively large objects such as rocks, tree roots, land mines, and peat soils, the objective of this study was to quantify comparatively smaller, particulate sources of SOC. This research used three materials as C sources: biochar, graphite, and activated C. The C sources were mixed with sand—12 treatments in total—and scanned under three moisture levels: 0%, 10%, and 20% to simulate different soil conditions. GPR attribute analyses and Naïve Bayes predictive models were utilized in lieu of visualization methods because of the minute size of the C particles. Significant correlations between GPR attributes and both C content and moisture levels were detected. The accuracy of two predictive models using a Naïve Bayes classifier for C content was trivial but the accuracy for C structure was 56%. The analyses confirmed the ability of GPR to identify differences in both C content and C structure. Beneficial future applications could focus on applying GPR across more diverse soil conditions.
