Soft Engineering River Management

What is flood plain zoning primarily used for?

• To increase urban development
• To create impermeable surfaces
• To build more houses on flood plains
• To categorise land into flood risk zones

How does afforestation help in flood management?

• By reducing surface runoff through leaf interception
• By increasing impermeable surfaces
• By creating more housing developments
• By removing trees from flood plains

Which of the following is an advantage of flood warnings?

• They are primarily internet-based and cheap
• They completely eliminate flooding
• They require expensive equipment to implement
• They are only effective in rural areas

What is one disadvantage of flood warnings?

• People may ignore them and not take action
• They are always accurate and reliable
• They require extensive physical infrastructure
• They are costly to implement

What is a disadvantage of flood plain zoning?

• It allows for more flood plain development
• It is very expensive to implement
• It increases the number of impermeable surfaces
• It can prevent development in areas with housing shortages

Which of the following is a disadvantage of afforestation?

• It can change the natural landscape and impact biodiversity
• It is the cheapest method of flood management
• It increases surface runoff significantly
• It has no impact on farming

What does river restoration aim to achieve?

• To return the river channel to its natural state
• To build more dams and barriers
• To increase agricultural land near rivers
• To create more urban developments

What is one benefit of flood plain zoning?

• It protects habitats by preventing development on flood plains
• It allows for rapid urban development
• It increases the amount of impermeable surfaces
• It is a very costly strategy

What is a key feature of flood warnings provided by the Environment Agency?

• They are only available to certain areas
• They require physical warning systems only
• They guarantee no flooding will occur
• They provide up-to-date flood alert information

What is an advantage of river restoration?

• Increased biodiversity through new wetland habitats
• It is the cheapest flood management strategy
• It allows for more urban development
• It does not affect agricultural land
