Flooding can occur due to a variety of natural and human-induced causes. The three major causes are:
1. Natural Causes
Heavy Rainfall: Intense storms can overwhelm drainage systems and cause rivers and streams to overflow.
Snowmelt: Rapid melting of snow in spring can lead to increased water flow in rivers.
Storm Surges: Hurricanes or tropical storms can push seawater inland, leading to coastal flooding.
River Overflow: Rivers can flood their banks due to excessive rainfall or upstream dam failures.
Tsunamis: Undersea earthquakes can generate massive waves that inundate coastal areas.
2. Human-Induced Causes:
Urban Development: Increased impervious surfaces (like concrete) prevent water absorption, leading to more runoff.
Deforestation: Removal of trees reduces the land’s ability to absorb rainfall, increasing surface runoff.
Poor Drainage Systems: Inadequate infrastructure can fail to handle heavy rain, resulting in flooding.
Dam Failures: Structural issues or excessive water can cause dams to break, leading to downstream flooding.
Climate Change: Changes in weather patterns can lead to more frequent and intense storms.

3. Other Factors
Topography: Low-lying areas are more susceptible to flooding.
Soil Saturation: Wet soils can’t absorb more water, leading to runoff.
Each flooding event can involve a combination of these factors, making effective management and preparedness essential.
