Study Notes
What is Flooding?
- Flooding occurs when heavy rainfall causes rivers to overflow, spreading water onto surrounding land.
Impacts of Flooding in China
- Injury and loss of life
- Crop failure
- Damage to buildings and infrastructure
- Disruption to transport services
- Disruption to utility services and electric supplies
- Pollution of drinking water
- Spread of diseases
Areas Prone to Flooding in China
- Eastern and southern parts, including coastal areas, are more prone to flooding.
Causes of Flooding in China
Physical Factors
- Heavy rainfall and typhoons
- Low relief (gentle slopes)
- Silting (deposition of soil and sand in river beds)
Human Factors
- Deforestation (leads to silting and increased river flow)
- Poor farming practices (overgrazing and over-cultivation)
- Reclaiming lakes for different uses (reduces lake sizes and holding capacity)
- Urban development (concrete surfaces and sewers/divert rainwater quickly)
