Aqueduct deposits suggest Plague of Cyprian may have emptied Nîmes around 270 A.D.

Researchers at Johannes Gutenberg University Mainz (JGU) have gleaned new insights into ancient water management in the French region around Nîmes by analyzing carbonate deposits within the Roman aqueduct that features the famous Pont du Gard bridge. Among other findings, the aqueduct—built around 50 A.D.—was expanded to include an additional water source after 11 years of operation; this event coincided with a historically documented dry spell. A century after the aqueduct's construction, the water supply to the city was deliberately throttled; it is likely that some of the water was diverted to agricultural land in the surrounding area instead.
