THE TIBER RIVER
 This river is the 3rd longest river in Italy and flows through the city of Rome and is 252 miles through Umbria and Lazio, where it is joined by Aniene river and
Tyrrhenian Sea. Rome was founded on the banks of Tiber, 16 miles from the sea at Ostia (Tiber River, 2015).
 In Rome, the Tiber river was very important to its trade and commerce, where their ships were able to reach as far as 60 miles upriver. This was also used to send grain, stone, timber, and foodstuff to Rome.

THE TIBER RIVER
 During the Punic Wars, the harbor at Ostia became a naval base and

eventually became its most important port where they ship wheat, wine, and oil around the Mediterranean. Romans also built wharves along the riverside which lines the riverbanks around the Campus Martius. They also connected the Tiber river with a sewer system and tunnels to send water to the mid-city (Tiber River, 2015).
 The river’s heavy sedimentation made it tough to maintain at that time, so the emperors had to create a new port on the Fiumicino. They built a new road to connect Rome with Fiumicino.

THE TIBER RIVER

 The navigation on the Tiber river was improved with extensive dredging which boosted the trade for a while, however, eventually it resulted to silting in the river and was only navigable as far as Rome (Tiber River, 2015).
 The river was also popular for its floods. It would usually flood as high as 6 feet
7 inches. It is now confined between high stone embankments since 1876. Also, in Rome, criminals were thrown into the Tiber and it continued over the years.
