Why were people flooded in the 19th century?

In the 19th century, people were often flooded due to a combination of natural disasters and human activity. Heavy rainfall, snowmelt, and hurricanes led to overflowing rivers and coastal areas. Additionally, inadequate infrastructure, such as poorly designed drainage systems and levees, exacerbated the situation. Urbanization and agricultural practices also contributed to increased vulnerability to flooding, as natural landscapes were altered and wetlands were drained.
