All Flashcards
Cause: Impervious surfaces. Effect?
Decreased groundwater recharge.
Cause: Urban runoff. Effect?
Water pollution and harm to aquatic life.
Cause: Increased runoff volume. Effect?
Soil erosion and flooding.
Cause: Polluted runoff. Effect?
Contamination of water bodies.
Why is urban runoff a problem?
Reduces groundwater, increases pollution, causes erosion.
How do impervious surfaces impact groundwater?
They prevent water from seeping into the ground.
What is the primary goal of runoff mitigation?
To increase water infiltration into the ground.
How does runoff affect marine ecosystems?
Increases freshwater input and pollution levels.
Why is vertical building a solution?
Reduces the amount of paved area needed.
How does runoff impact aquatic life?
Pollutes water, harming or killing organisms.
What is urban runoff?
Water from rain/snow flowing over man-made surfaces.
Define impervious surfaces.
Surfaces that prevent water infiltration (e.g., roads).
What is permeable pavement?
Pavement that allows water to seep through.
What are green roofs?
Vegetation planted on rooftops to absorb rainwater.
What are rain gardens?
Depressions planted to collect and filter runoff.
