Urban Runoff and Green Infrastructure

Mr. Smith discusses urban runoff, its environmental consequences, and various mitigation techniques. The video covers the impact of impervious surfaces on groundwater infiltration and pollution. Solutions like permeable pavement, rain gardens, and public transportation are explored. The video concludes with a practice exercise on designing a research experiment related to urban runoff.

What is the primary objective of the lesson on urban runoff?

• To promote urban sprawl

• To describe methods to mitigate urban runoff

• To increase urban runoff

• To eliminate all urban runoff

Which of the following is a consequence of urban runoff?

• Decreased groundwater infiltration

• Reduced pollution

• Increased groundwater recharge

• Improved air quality

What is a major benefit of using permeable pavement?

• It prevents all types of pollution

• It allows water to infiltrate and recharge groundwater

• It increases urban runoff

• It is cheaper than standard concrete

What is a drawback of permeable pavement?

• It increases flooding

• It is more expensive than standard concrete

• It does not allow water infiltration

• It is harmful to plants

How do rain gardens help in reducing urban runoff?

• By increasing impervious surfaces

• By increasing the volume of stormwater

• By blocking storm drains

• By filtering pollutants and reducing stormwater volume

What is one benefit of using public transportation in urban areas?

• It increases CO2 emissions

• It increases the number of cars on the road

• It reduces pollutants on roads

• It requires more parking lots

What is the impact of building vertically in urban areas?

• It increases CO2 emissions

• It promotes urban sprawl

• It decreases the amount of runoff

• It increases impervious surfaces

How does vertical building combined with green infrastructure benefit cities?

• It increases impervious surfaces

• It lowers healthcare costs and reduces urban smog

• It reduces air quality

• It increases urban smog

What is a key difference between Atlanta and Barcelona in terms of urban planning?

• Barcelona uses effective transportation systems and has less urban sprawl

• Atlanta has fewer CO2 emissions per person

• Barcelona has more impervious surfaces than Atlanta

• Atlanta has less urban sprawl than Barcelona

What role do trees play in urban areas regarding stormwater runoff?

• They increase stormwater runoff

• They sequester carbon dioxide and reduce runoff

• They block storm drains

• They increase impervious surfaces
