Urban Drainage Flashcards
What is urban drainage?
Urban drainage refers to the system that manages the collection, transport, and treatment of stormwater and wastewater in urban areas.
True or False: Urban drainage strategies can help reduce flood risk.
True
What is the primary goal of urban drainage strategies?
The primary goal is to manage stormwater effectively to prevent flooding and waterlogging in urban areas.
Fill in the blank: Urban drainage systems often include ________ and retention basins to manage stormwater.
detention ponds
Name one benefit of green infrastructure in urban drainage.
Green infrastructure enhances water absorption and reduces runoff.
What role do permeable pavements play in urban drainage?
Permeable pavements allow water to infiltrate through surfaces, reducing runoff and flood risk.
Multiple Choice: Which of the following is NOT a component of urban drainage systems? A) Sewers B) Detention basins C) Highways D) Green roofs
C) Highways
How do bioswales assist in urban drainage?
Bioswales are designed to capture and filter stormwater, reducing runoff and improving water quality.
True or False: Urban drainage strategies can only be implemented in new developments.
False
What is a common consequence of inadequate urban drainage?
Inadequate urban drainage can lead to increased flooding and water pollution.
Fill in the blank: The use of ________ can help to increase the capacity of urban drainage systems.
storage tanks
What is the function of a rain garden in urban drainage?
Rain gardens capture and absorb rainwater, reducing runoff and promoting groundwater recharge.
Multiple Choice: Which of the following is a benefit of urban drainage strategies? A) Increased flood risk B) Improved water quality C) More impervious surfaces D) Higher maintenance costs
B) Improved water quality
What is the importance of regular maintenance in urban drainage systems?
Regular maintenance is crucial to ensure systems function effectively and prevent blockages that can lead to flooding.
True or False: Urban drainage strategies can help mitigate the effects of climate change.
True
What is the role of floodplain management in urban drainage?
Floodplain management involves regulating land use in flood-prone areas to minimize flood risk.
Fill in the blank: Urban drainage strategies often incorporate ________ to enhance resilience against heavy rainfall.
sustainable drainage systems (SuDS)
How does urban vegetation contribute to drainage?
Urban vegetation helps absorb rainwater, reducing surface runoff and enhancing drainage.
Multiple Choice: Which strategy is commonly used to slow down stormwater runoff? A) Concrete channels B) Green roofs C) Steel drains D) Asphalt surfaces
B) Green roofs
What is an overflow drainage system?
An overflow drainage system is designed to manage excess water during heavy rain events, directing it safely away from urban areas.
True or False: Urban drainage improvements can lead to higher property values.
True
What is the impact of urbanization on natural drainage patterns?
Urbanization typically disrupts natural drainage patterns, increasing runoff and flood risk.
Fill in the blank: The integration of ________ into urban planning can significantly improve drainage efficiency.
land use planning
What is the purpose of a stormwater management plan?
A stormwater management plan outlines strategies to manage stormwater runoff and reduce flood risk effectively.
