How did river make the development of Rome difffecult?

The Tiber River, while crucial for trade and transportation, posed challenges for the development of Rome due to its unpredictable flooding. These floods could damage infrastructure and agricultural lands, making it difficult for the city to maintain a stable food supply. Additionally, the river's marshy banks created health hazards, contributing to the spread of diseases like malaria. These environmental factors complicated urban planning and necessitated ongoing efforts to manage the river's impact on the growing city.
