<P> The river rises at Mount Fumaiolo in central Italy and flows in a generally southerly direction past Perugia and Rome to meet the sea at Ostia . Popularly called flavus ( `` the blond '' ) , in reference to the yellowish colour of its water , the Tiber has heavily advanced at the mouth by about 3 kilometres ( 2 miles ) since Roman times , leaving the ancient port of Ostia Antica 6 kilometres ( 4 miles ) inland . However , it does not form a proportional delta , owing to a strong north - flowing sea current close to the shore , to the steep shelving of the coast , and to slow tectonic subsidence . </P>
