STORMWATER MANAGEMENT

What is the main function of campus drainage systems during rainfall?

• To collect and redirect rainwater away from buildings and walkways

• To irrigate the campus gardens

• To increase the flow of groundwater

• To filter pollutants from the air

Which of the following features is typically part of a drainage system on a campus?

• Retaining walls

• Stormwater inlets or grates

• Streetlights

• Playground equipment

What tool would you use to measure the slope of the terrain on campus to assess water flow direction?

• Total Station

• Soil probe

• Water quality tester

• Compass

Which areas of the campus are likely to produce the most stormwater runoff?

• Sports fields with grass

• Parking lots and paved walkways

• Forested areas

• Garden beds with shrubs and plants

Why is it important to identify and monitor stormwater outfalls during the campus survey?

• To ensure rainwater reaches the nearest river

• To assess the discharge point where stormwater leaves the campus, ensuring proper drainage and preventing flooding

• To check the quality of drinking water

• To irrigate sports fields

What is the purpose of a detention basin on a campus?

• To permanently store rainwater

• To temporarily hold and slowly release stormwater to prevent flooding

• To channel water directly into underground pipes

• To increase groundwater recharge

How can you determine if a drainage grate is clogged during your survey?

• By measuring the depth of water near the grate

• By visually inspecting the grate for debris like leaves or litter blocking water flow

• By checking the weather report

• By testing the water quality near the grate

Which landscape feature helps to naturally absorb rainwater and reduce runoff on campus?

• Paved pathways

• Lawns and vegetated areas

• Rooftops

• Sports courts

Why is it important to evaluate the slope of walkways and parking lots during a drainage survey?

• To determine the location of the drainage grates

• To assess how quickly water will accumulate and run off the surface during rainfall

• To check for water quality

• To decide where to plant trees

What is the main consequence of inadequate drainage systems on campus during heavy rainfall?

• Improved plant growth

• Increased risk of flooding and water damage to buildings

• Better water quality in campus streams

• More recreational spaces for students
