Addressing the 14th Annual Symposium on the Iranian Archaeology, that ended at Iran National Museum in Tehran (March 6-8) on Tuesday, Eberhard said the experiment had been made by Richard Batrtes, Hamid Omrani Rekavandi, Bardia Shabani and others.
Eberhard's lecture themed: Engineering and safeguarding prosperity in the Sasanian Empire: The 1394/2015 season on the Great Wall of Gorgan and its hinterland by the Iranian Cultural Heritage, Handicraft and Tourism Organization and the University of Endinburgh.
He said it continues in a straight alignment to 40S, 0233480, 4079320.
In the east it is lined by a ditch which, like the northernmost section of the wall, is covered by marine sediments, he added.
The terminals of wall and ditch are sufficiently distinct to suggest that the wall does not continue beyond this point and that the earlier hypothesis that the Gorgan and Tammisheh Walls are linked, is probably mistaken, the scholar said, adding conditions for survey were less favorable to the west and southwest of the Gorgan Wall as the sonar was unable to penetrate recent organic alluvial sediments.
He announced that whilst further fieldwork is needed to locate the western terminal of the Gorgan Wall, it seems likely that both walls terminated in the vicinity of the contemporary shore (at c. 32m from bypassing coastal wall terminals in shallow water.
Wooden piers and naval forces may have been effective, if hard to trace archaeologically, he concluded.

Tehran, March 8, IRNA – Professor of Roman Archaeology in School of History, Classics and Archaeology in the University of Edinburgh in the UK, Professor Eberhard W. Sauer, says underwater sonar survey succeeded in tracing the Tammisheh Wall for more than 900 m further than the sections known so far.
