Causes of Flooding

Flooding can result from both natural and human-induced factors:

Natural

• Heavy Rainfall: Intense or prolonged precipitation can saturate the ground and exceed the capacity of rivers and drainage systems, leading to flooding. ​
   
• Snowmelt: Rapid melting of snow and ice can release large volumes of water into rivers and streams, causing them to overflow.
   
• Storm Surges: Strong winds from storms or hurricanes can push seawater onto coastal lands, resulting in coastal flooding. ​
   
• Ice or Debris Jams: Accumulations of ice or debris can obstruct river flow, causing water to back up and overflow the banks.

Human-induced Causes

• Deforestation: Removal of trees reduces the land's capacity to absorb rainfall, increasing surface runoff and the risk of flooding.
   
• Urbanization: The expansion of impervious surfaces like roads and buildings decreases natural infiltration, leading to increased runoff and overwhelmed drainage systems.
   
• Poor Land Use Practices: Activities such as improper agricultural practices and construction can alter natural water flow and reduce the land's ability to absorb water. ​
   
• Infrastructure Failures: Failure of man-made structures like dams, levees, or drainage systems can lead to sudden and severe flooding.
   
• Climate Change: Changes in climate patterns can lead to more frequent and severe weather events, including heavy rainfall and storms, thereby increasing the risk of flooding. ​
