Factors affecting flood risk
I can explain the physical and human factors that affect flood risk, and why flood risk is increasing.
Lesson details
Key learning points
- Physical and human factors increase flood risk.
- Increased flood risk is due to several factors including increased storm frequency (and intensity) and land use change.
- Increased river flooding threatens people and the environment.
Keywords
Flood risk - the probability of a flood event occurring and its potential impact
Relief - physical shape or features of the land's surface
Urbanisation - the increase in the proportion of people living in cities and towns, often impacting natural land
Climate change - long-term shifts in temperatures and weather patterns, often linked to human activity
Common misconception
The only factor affecting flood risk is rainfall.
Whether a river floods in response to heavy rainfall also relates to many other factors, especially how quickly and in what volume rainfall enters the river.
