Hydraulic capacity of ancient water conveyance systems to Ephesus

Ephesus was supplied by several long-distance water conveyance systems in ancient times. The 8 km long Şirince water conveyance system consists of baked clay pipes, and had a hydraulic capacity of around 10 l/s. The 7 km long Derbentdere water conveyance system consists also of baked clay pipes; and its hydraulic capacity was around 20 l/s. The 36 km long Değirmendere water conveyance system is a masonry conduit; its hydraulic capacity was around 200 l/s. The 42 km long Kayapınar water conveyance was also a masonry conduit; its hydraulic capacity was around 100 l/s. The Şirince system was extended over to the Ayasuluk hill and Saint John basilica in the 6th century ad by the 650 m long Selcuk aqueduct, serving as the venter of an inverted siphon.
