Mitigating Urban Flood Impact

Click on the flashcard to see the answer

What are urban floods?

Urban floods are inundations in city areas due to intense rainfall exceeding stormwater drainage capacity.

Why are urban floods more common in cities?

Cities have numerous impermeable surfaces, reducing water absorption and increasing surface runoff.

How does climate change contribute to urban floods?

Climate change increases rainfall intensity and frequency, raising the risk of flooding.

What is stormwater management?

Stormwater management involves controlling rainwater runoff through systems like drains and retention basins.

How can green roofs help in flood mitigation?

Green roofs absorb and store rainwater, reducing runoff.

What role do permeable pavements play?

Permeable pavements allow rainwater to seep through, reducing runoff and flooding.

How do retention ponds mitigate flooding?

Retention ponds hold excess stormwater and release it slowly.

Why is public awareness important in flood mitigation?

Informed citizens can take precautions to protect themselves and their property.

What is the role of urban planners in managing floods?

Urban planners design cities with infrastructure to prevent and manage flood risks.

How do flood prediction systems help reduce flood impacts?

They provide early warnings, allowing for timely evacuations and preparations.

What is a floodplain?

A floodplain is the area adjacent to a river or stream that floods naturally.

How can nature-based solutions aid in flood mitigation?

Nature-based solutions use natural processes to manage water and reduce floods.

What is a flood barrier and how does it work?

Flood barriers are structures that block water from entering certain areas.

Why is inter-agency coordination important during urban floods?

Coordination ensures effective disaster response and resource sharing.

What is sustainable drainage system (SuDS)?

SuDS manage rainwater using natural processes to mimic natural water handling.
