Flooding is worsening with climate change and urban growth. Learn what causes floods, their impacts, and how to build resilience.
The Basics of Flooding Key Takeaways
Key Takeaways:
Flooding is the overflow of water onto normally dry land, resulting from various natural and human-induced factors.
Types of flooding include fluvial (river), pluvial (surface water), coastal, flash, groundwater, and urban flooding, each with distinct causes and characteristics.
Natural causes of flooding encompass heavy rainfall, rapid snowmelt, storm surges, and ice or debris jams.
Human-induced factors such as deforestation, urbanization, poor land use practices, and infrastructure failures can exacerbate flood risks.
Climate change is leading to more frequent extreme weather events and higher sea-levels, resulting in a higher risk of flooding.
