Abstract
”Geophysical surveys are widely most common in the archaeological prospection for imaging the buried objects. The accuracy and resolution of the generated images are crucial parameters for excavation decision. Thus, the integration of the different geophysical techniques helps in overcoming the limits of each method and reduces the ambiguity of the interpreted data, especially when the physical contrast between the archeological remains and the host medium is very low. This is the case of San El-Hager (Tanis) site, which is considered one of the most important and richest archaeological sites in the Nile Delta region, Egypt. It has been selected to investigate its undiscovered areas. In this study, the integrated magnetic, 2D and 3D electrical resistivity tomography (ERT) as well as 3D ground penetrating radar (GPR) surveys have been carried out and combined with the auxiliary geological, geomorphological, and archeological data to image the undiscovered areas within Tanis site. The GPR survey has been carried out along different areas at North Tanis, where five sectors have been selected to be interpreted. Three sectors of them have been chosen to be surveyed by ERT. One area of them has been carried out by magnetic method to be a selective example of integration of three methods. The GPR survey has been carried out using frequency values of 100, 200, and 600MHz with different profile spacing according to the surveyed area. Moreover, ERT profiles were performed along the same GPR lines for integration using the Wenner Beta (WB) and dipole-dipole (DD) arrays with 1 m electrode spacing. Based on the output results of the GPR and ERT methods, an area has been chosen to carry out the gradient magnetic survey with 50 cm spacing interval. The processed and integrated results of the GPR, ERT and magnetic surveys have illustrated possible buried archaeological remains within the top 2 m of a clay layer, which is underlained by the turtle-back sand island in the area of study. The deduced archeological remains have been confirmed through further investigation by the archaeologists.
