Investigation of the Roman Defence Wall by using Multi-Electrode Resistivity System

O5 - 01 ENVIRONMENTAL ENGINEERING & ARCHAEO-GEOPHYSICS INVESTIGATION OF THE ROMAN DEFENCE WALL BY USING MULTI-ELECTRODE RESISTIVITY SYSTEM Mehmet Emin Candansayar Ankara University Faculty of Science Geophysical Eng. Dept. 06100 Besevler-Ankara Turkey Summary I investigate a defense wall used in late Roman and early Ottoman Empire period by using multi electrode direct current resistivity system in Ankara the capital city of Turkey. I suggested a 2x2 meter area for excavation after two-dimensional inversion of pole-dipole and Schlumberger arrays data interpretation. The wall constructed in the Roman period (B.C. 300) was found in 4 meter depth. This result validated the resistivity
