Long-Term Interactions between the Roman City of Ostia and Its Paleomeander, Tiber Delta, Italy

摘要: This study examines the long term interactions between well-known Roman city of Ostia and a river meander. Located at mouth Tiber River, was major harbor that connected Rome to Mediterranean Sea. Based on aerial photography boreholes analysis, paleodynamics Fiume Morto’s paleomeander are understood be linked urban evolution Ostia. Four periods have been identified as result this interdisciplinary work: (1) foundation Ostia’s center, in 4th – 3rd century BC, occurred when meander already existed; (2) BC AD, human/environmental contributed compound growing which possibly eroded an important road linking Rome; (3) from Imperial period until cut off AD 1557-1562, constricted channel apex led stability downstream channel; (4) completed 1562, leading filling paleochannel. These successive phases mark changing fluvial risks today.
