“…Numerous topographical and hydrological uses of the GPR have been portrayed by Davis and Annan (1989), Annan et al (1991), Doolittle (1993. In like manner, the procedure has been effectively utilized in archeological investigations (Goodman, 1994;Goodman et al, 1995;Conyers and Goodman, 1997;Leckebusch, 2000;Tomizawa et al, 2000).…”

Archaeological Investigation and Hazard Assessment Using Magnetic, Ground-Penetrating Radar, and GPS Tools at Dahshour Area, Giza, Egypt

An archeological study using magnetic and ground-penetrating radar methods has been performed at the Dahshour region (Giza, Egypt), where various covered structures have not been found because of the long coercion of the zone under the military specialists. Dahshour is the southern extension of the Saqqara and Giza Pyramids plateau, around 25 km south of Cairo. The area is known for its colored pyramids—the white, red, and black pyramids, and the famous Bent Pyramid. Four investigation sites were chosen around the Bent Pyramid complex. The geophysical investigation has revealed the presence of some buried structures made up of mud bricks such as tombs, mud-brick walls, causeway, and remains of an ancient temple. Numerous limestone blocks were also detected. The study indicates the possible existence of an older valley temple made up of mud bricks and confirms the existence of another causeway that led to the Nile Valley. To protect the Egyptian heritage around this vital area, a detailed computation of the current crustal stress/strain state has been performed by taking into account all the available GPS observations. Achieved results indicated that the southern and the southeastern sectors of the investigated area are currently accumulating strain, and this means that there is a possibility for future earthquakes to occur around this vital archaeological area. Buried structures are preserved by confinement in the burial materials like a large mold. However, external load or stress can still cause damage. Therefore, during excavation, the stress should be reduced to avoid wall collapsing and structure damage. Therefore, it is recommended to start excavation from the stress direction from the southern side.

In this work, the results of high-resolution integrated geophysical surveys of the archaeological site of Traiano's Villa (Altopiani di Arcinazzo, Roma, Italy) are presented. The Villa of Roman Emperor Marco Ulpio Traino (AD 98-117) was built in Arcinazzo (Italy), approximately 55 km northeast of Rome. Today, the only remains left standing at the site are the public building entrances comprising a small portion of the entire site. Over 5 ha, adjacent to the entrance remains, had not been surveyed. As part of an ongoing study to rescue this national archaeological treasure, highresolution ground-penetrating radar (GPR) surveys, using a submetre profile spacing, integrated with a gradiometric survey, were conducted. Amplitude GPR time-slice analysis indicates that many structural foundations and walls of the villa are still well preserved below the surface. Timeslices below 1.5 m in one area indicate two large mushroom shaped structures enclosed within a large building over 100 m in length. These structures are believed to be dipping pools within a larger structure believed to be the bathhouse to the villa. At the location west of the bathhouse a large oval shaped anomaly 45 m along its major axis was located. This subsurface structure is believed to be an oval garden pond or a swimming pool. Several other remnants of rectangular buildings coincident with the oval structure but much deeper were also imaged. Other structures include a long rectangular corridor that contains many square shaped rooms, which has been interpreted as a criptoporticus. The magnetic map, related to part of the area investigated, shows many dipole anomalies. These anomalies represent linear and semicircular structures of the villa. The magnetic results provide complementary information to the GPR survey that lines out walls and floors.

This article gives an overview of the various aspects of ground-penetrating radaras used in archaeology. Aftera short overview ofthe historicaldevelopment ofthe technique, the most important physical parameters and principles are explained. This includes relative dielectric constant, conductivity, attenuation, horizontal and vertical resolution, wavelength and footprint.The focus is on data processing and some ofthe pitfallsinvolved.Severalalgorithmsfrom seismic data processing are described, including migration. Stress is laid on the generation of time-or depth-slices as the basis for displaying the data. Using three-dimensional visualization techniques can enhance this, but interpretation in combination with other data, preferably within a geographical information system, remains the important last step.The advantages of modelling are explained and presented with the range of possible applications. Many the techniques and methods described are subsequently used in four case histories, ranging from a survey on a lake to a three-dimensional model of a part of a roman town.Finally some thoughts about the future development of the method are presented.
