dc.description.abstract [EN] This paper describes the ground-penetrating radar (GPR) survey carried out on the Roman theatre of Sagunto (Valencia, Spain) following recent restoration work in 1991. The structure has been substantially altered a number of times: it was remodelled during the Roman and Moorish periods, partially destroyed during the Peninsular War (1808-1814) and the Carlist War (1833-1839), and extensively modified during the 1930s and 1950s. Major reconstruction work was carried out in 1991 to convert the building into a working theatre. The GPR survey was performed to detect the possible effects of the 1991 remodelling on the historical remains and to identify the point of contact between the present-day modifications and the Roman remains. We took several on-site measurements of the wave velocity in the different materials in known areas to determine as accurately as possible the depth of the contact point. The velocity was calculated by measuring the depth in these areas and the two-way travel time of the wave. The measurements were taken from the walls and the tiers as the thicknesses of the materials were known in these areas. The recorded values were compared with the velocities reported by other authors and with the information from diffraction hyperbolas recorded in the radar data, which are caused by small objects inserted in the medium. We used these velocities to determine the exact point of contact between the Roman remains and the materials used in later restorations. The contact points cause the reflections that can be seen in the GPR data. The results also reveal considerable variations in the surface of the Roman tiers, which can be attributed to partial erosion in these areas caused mainly by water. es_ES
dc.description.sponsorship This study was partially funded by the research projects CGL-2005-04541-C03-02/BTE of the Sub-directorate General of Research Projects of the Spanish Ministry of Education and Science, and REN2003-07170 of the Spanish Ministry of Science and Technology. Additional support was provided by the School of Civil Engineering of Barcelona (ETSECCPB). We would like to thank all those at the Technical University of Catalonia and the Technical University of Valencia who helped us during the radar data acquisition. Their assistance with the field surveys was greatly appreciated. The authors also would like to thank the Editor-in-chief Prof. P.A. Vigato, who carefully handled this manuscript, the anonymous reviewers for their constructive comments that help to improve the text, and Dra. Eleonora Maria Stella for editorial assistance.
