AP®︎ Environmental Science: Topic 5.13 Flashcards

Rainwater or snowmelt that flows over developed land instead of infiltrating into soil

A human-made surface that prevents or greatly reduces water from reaching soil, increasing surface runoff

Movement of water from the land surface into soil, leaving less water available for immediate runoff

Pavement with pores or openings that let water pass into underlying gravel and soil, reducing runoff volume and peak flow

Trees reduce runoff by intercepting rainfall, improving soil infiltration through their roots, and returning water to the atmosphere through evapotranspiration

Using mass transit to reduce demand for roads and parking, preserving more vegetated and permeable land

Concentrating development in taller buildings so the same activity occupies less land, preserving permeable open space

Vegetation, soil, and permeable surfaces used to capture, slow, store, or infiltrate stormwater

Shallow vegetated areas that receive runoff, slow it, and allow it to infiltrate into amended soil

A rooftop layer of growing medium and vegetation that retains precipitation and delays and reduces roof runoff

A strip of vegetation that slows runoff and promotes infiltration before water reaches a stream or storm drain

A basin that temporarily stores stormwater so it can soak into the ground

A pond that temporarily stores stormwater and releases it gradually, reducing peak discharge and flood risk

A pond that maintains a permanent pool and provides additional storage for stormwater
