The myth may have explained a memory of an earlier, perhaps
pre-Indo-European name for the river, "white" (''alba'') with sediment, or "from the mountains" from
pre-Indo-European word "alba, albion" mount, elevated area. ''Tiberis/Tifernus'' may be a pre-Indo-European substrate word related to
Aegean ''tifos'' "still water", Greek
phytonym ''τύφη'' a kind of swamp and river bank weed (''
Typha angustifolia''),
Iberian hydronyms ''Tibilis, Tebro'' and
Numidian ''Aquae Tibilitanae''. Yet another etymology is from *dubri-, water, considered by Alessio as
Sicel, whence the form Θύβρις later Tiberis. This root *dubri- is widespread in Western Europe e.g. Dover, Portus Dubris.

The Tiber was critically important to Roman trade and commerce, as ships could reach as far as upriver; some evidence indicates that it was used to ship grain from the Val Teverina as long ago as the fifth century BC.
It was later used to ship stone, timber, and foodstuffs to Rome.

Wharves were also built along the riverside in Rome itself, lining the riverbanks around the
Campus Martius area. The Romans connected the river with a sewer system (the ''
Cloaca Maxima'') and with an underground network of tunnels and other channels, to bring its water into the middle of the city.
Wealthy Romans had garden-parks or ''horti'' on the banks of the river in Rome through the first century BC. These may have been sold and developed about a century later.
The heavy sedimentation of the river made maintaining Ostia difficult, prompting the emperors

and
Trajan to establish a new port on the Fiumicino in the first century AD. They built a new road, the ''
Via Portuensis'', to connect Rome with Fiumicino, leaving the city by
Porta Portese (the port gate). Both ports were eventually abandoned due to silting.
Several
popes attempted to improve navigation on the Tiber in the 17th and 18th centuries, with extensive dredging continuing into the 19th century. Trade was boosted for a while, but by the 20th century, silting had resulted in the river only being navigable as far as Rome.
The Tiber was once known for its floods — the Campus Martius is a
flood plain

and would regularly flood to a depth of . The river is now confined between high stone embankments, which were begun in 1876. Within the city, the riverbanks are lined by boulevards known as ''
lungoteveri'', streets "along the Tiber".
Because the river is identified with Rome, the terms "swimming the Tiber" or "crossing the Tiber" have come to be the shorthand term for converting to
Roman Catholicism. A Catholic who converts to Protestantism, in particular Anglicanism, is referred to as "swimming the
Thames" or "crossing the Thames".
In ancient Rome,
executed criminals were thrown into the Tiber. People executed at the
Gemonian stairs were thrown in the Tiber during the later part of the reign of the emperor
Tiberius. This practice continued over the centuries. For example, the corpse of
Pope Formosus was thrown into the Tiber after the infamous
Cadaver Synod held in 897.
Bridges
In addition to the numerous modern
bridges over the Tiber in Rome, there remain a few
ancient bridges (now mostly pedestrian-only) that have survived in part (e.g., the
Ponte Milvio and the
Ponte Sant'Angelo), or in whole (
Pons Fabricius).
In addition to bridges, the Metro trains use tunnels.
Representations
Following the standard Roman depiction of rivers as powerfully built reclining male gods, the Tiber, also interpreted as a god named
Tiberinus, is shown with streams of water flowing from his hair and beard.
In popular culture
In the ''
Command & Conquer'' video game series, the alien mineral the game revolves around, Tiberium, was first discovered by, and named after, the Tiber River.
In Part 5 of the manga series
JoJo's Bizarre Adventure, the final conflict between the characters occurs on a street adjacent to the Tiber River, and ends with Diavolo's body flying into it.
2022 Heatwave
In 2022, there was a big heatwave in Europe. As a result of these, the water levels dropped and a number of objects emerged. Some of these objects include world war 2 shipwrecks, bombs and a 2000 year old bridge.
