Garbrecht in the late 1980s has raised some doubts whether Procopius's account are to be interpreted as referring to an arch dam. Garbrecht was able to identify a dam site near the ancient city-walls whose characteristics were consistent with Procopius' precise description – with the
142:
At a place about forty feet removed from the outer fortifications of the city, between the two cliffs between which the river runs, he constructed a barrier of proper thickness and height. The ends of this he so mortised into each of the two cliffs, that the water of the river could not possibly get

Procopius makes two essential points clear: first, the dam had a curved plan in order to withstand the water pressure, and did not follow a more or less curved line just because this was where the most solid bedrock was found, and secondly, the thrust of the water was not contained by the sheer

by that point, even if it should come down very violently...This barrier was not built in a straight line, but was bent into the shape of a crescent, so that the curve, by lying against the current of the river, might be able to offer still more resistance to the force of the stream.
