July, 2017: Workshop on wells and cisterns (Athens, September 28-29, 2017)(workshop)

The workshop 'Going Against the Flow, wells, cisterns and water in ancient Greece' focuses on the use of wells and cisterns, how these installations functioned and were used in ancient Greece, as well as how they can be better integrated into our understanding of the ancient water supply.
The workshop is divided into two parts. The first is centred on the water sources in their context, discussing use, function and terminology. The second is on contextualisation from other perspectives and disciplines.

The workshop will he help in the Swedish Institute at Athens, 28 - 29 September 2017. Organiser is Dr. Patrik Klingborg, Uppsala University, Engelska Parken, Thunbergsvägen 3H, Uppsala, Sweden, tel: +46736151874.

January 2017: An additional stretch of the Viminacium aqueduct (Serbia) discovered (excavations)

Excavation brought to light the remains of the Roman aqueduct from 1st century CE, at Viminacium, the Roman fortified town and legionaries camp in present-day eastern Serbia, near Kostolac. Archaeologists have discovered about 1.000 meters of the Roman aqueduct, geophysical methods showed another 1,800 meters, while remote detection found an additional 1,350 meters of it.
It was built by Roman soldiers from two legions – Legio III Flavia Felix and Legio VII Claudia Pia Fidelis. The aqueduct was built of stone, bound with lime mortar. The sides of the aqueduct were covered with lime mortar too, and the underneath layer was made of water resistant mortar. The bottom was built of fire-baked bricks with stamps of the Roman legions that have built it. In the upper part, the aqueduct was covered with massive floor bricks. Its total length was about 10 kilometers.

November, 2016: the Roman road, the monumental arch and the aqueduct in Tyr (book)

This book focuses on monuments of the site of Tyre el-Bass (close to present Sour, Lebanon), one of two main archaeological areas of Tyre city in an extra-urban position: the ancient road, the monumental arch and the aqueduct. The ancient road is the backbone of the site. The monumental arch dates back to the end of the first century CE and spans the ancient road just before the circus; its function would have been that of an urban gateway defining the limits of the municipal area and acting as a customs post.
The aqueduct is at the southern side of the road that captures the sources of Ras al-Ain, located 5 km to the south of the city. This aqueduct extends to a 7 km length and has several sections, some of which are well preserved.
Price € 55, 238 pages.

November, 2016: New dating of the famous aqueduct of Segovia (Spain)

El País reports that the discovery of a coin has revised the construction date for the Segovia Aqueduct to the early years of the second century A.D. A team of researchers analyzed materials collected during an excavation at three of the aqueduct's pillars in the Plaza del Azoguejo, the city's old market square, in 1998. The fill in the foundations included ceramics from workshops in La Rioja dating to the first third of the second century A.D., and a Roman coin minted between A.D. 112 and 116. Previous studies of anchors used to hang large bronze letters on the arches of the aqueduct suggested that the structure had been erected around A.D. 98.

April 2016: How to date sinter by 230 Th/U-method (scientific article)

Carbonate deposits in aqueducts, known as calcareous sinter, can reach a considerable thickness and are commonly annually laminated. Environmental and palaeoclimate proxies measured in calcareous sinter samples, such as stable oxygen and carbon isotopes and trace elements, can provide important highresolution information on hydrological conditions, temperature, and local precipitation in the catchment area of an aqueduct. In order to utilize the proxy data for palaeoclimate reconstruction, the sinter deposits must be dated by annual laminae counting and more precisely by 230Th/U-dating. Here a systematic approach is presented to date sinter deposits from various locations in western and eastern Europe using the 230Th/U-method.

Officials of the Nature Protection Service (Seprona) of the Guardia Civil of Morón de la Frontera (Seville, Spain) investigate a farmer of Osuna for an alleged crime against the historical heritage by expelling deposits of the first century BC. The investigation began after the Guardia Civil was informed by the archaeologist of the City of Osuna that the archaeological site near the Blanco river, in the place Cortijo de Girón, consisting of an aqueduct of Roman times, had been totally looted. The entire structure having been destroyed since the clay bricks that made it had been removed. These remains were unique in Andalusia and the construction was an engineering work of which there is no other documented in this area. Bricks of the ancient aqueduct would have been used to construct a new shed.

February 2016: Roman-era canal system unearthed near Dead Sea (excavation)

An ancient canal system used 2.000 years ago to irrigate terraced agricultural plots has been unearthed in an excavation near the Roman-era fortress of Metzad Bokek in southern Israel. The Israel Antiquities Authority (IAA) and the Israel Nature and Parks Authority (INPA) jointly conducted the excavation. The system used gravity to carry water from the Ein Bokek spring to the terraces. The longest of the canals measures almost 2 km (1,2 miles). Noah Michael, the archaeologist directing the dig for the IAA, said that "the canal system, which connected irrigation pools and linked to an aqueduct that conducted water from the spring, was plastered and apparently covered".

June 2015: Travertine reveals ancient water supply at the Anio Novus aqueduct (Rome)

Although popular with modern scholars, ancient flow rate measurements in Rome's aqueducts are unreliable since they only recorded flow section, not velocity. Use of limestone deposits - called travertine or sinter - as a record of wetted perimeter, enabled the first estimation of actual flows in Rome's Anio Novus aqueduct. Final flows reaching Rome, in the presence of thick travertine deposits, were significantly smaller, at 1.4 ± 0.4 m3/s (120,960 ± 34,560 m3/day), than previous maximum and minimum estimates. Lack of maintenance and/or changes in water use may have contributed to this difference. Even minimal travertine reduced the maximum flow rate by ~25%.
