Review Questions

• How did the management of levees contribute to the severity of the Great Mississippi Flood?
  • The management of levees before and during the Great Mississippi Flood played a crucial role in the flood's severity. Many levees were poorly maintained or inadequately designed, which failed to contain the unprecedented rainfall and river flow. When the levees eventually broke or were overtopped, large areas experienced catastrophic flooding, demonstrating that inadequate flood management practices significantly contributed to the disaster's impact.
• What were some major social and economic impacts of the Great Mississippi Flood on affected communities?
  • The Great Mississippi Flood had devastating social and economic impacts on affected communities. Over 700,000 people were displaced from their homes, leading to a humanitarian crisis. The destruction of crops and infrastructure devastated local economies, while many families faced long-term recovery challenges. This event also accelerated demographic shifts, as large numbers of African Americans migrated from the rural South to urban areas in search of better living conditions and job opportunities.
• Evaluate how the Great Mississippi Flood influenced future flood management policies in the United States.
  • The Great Mississippi Flood served as a turning point for flood management policies in the United States by highlighting significant vulnerabilities within existing systems. In response to the disaster, lawmakers enacted the Flood Control Act of 1928, establishing guidelines for improved levee construction and maintenance, as well as enhanced flood forecasting. This event spurred further investment in flood control infrastructure and laid the groundwork for contemporary flood management strategies aimed at reducing risks associated with natural disasters.
