detention basin

A detention basin temporarily holds rainwater to prevent flooding downstream.

Definition
  1. Noun:
    • A storage site (such as a small reservoir) that delays the flow of water downstream: A detention basin is a constructed or natural depression designed to temporarily hold stormwater runoff. Its primary purpose is to control the rate at which water is released into a downstream watercourse, helping to mitigate flooding and reduce erosion.
Usage Examples
  • Noun:
    • The new housing development includes a large detention basin to manage stormwater.
    • After the heavy rain, the detention basin was full, but it slowly released the water over the next 24 hours.
    • Engineers designed the detention basin to hold excess runoff during peak flow periods.
Advanced Usage
  • "Dry detention basin": A basin that is typically dry except during and immediately after a rainfall event.
    • The park doubles as a dry detention basin during storms.
  • "Extended detention basin": A basin designed to detain water for a longer period, often to improve water quality by allowing sediments to settle.
    • The extended detention basin is part of the city's strategy for cleaner waterways.
Variants and Related Words
  • Detention pond: A synonym often used interchangeably with detention basin.
    • The detention pond successfully prevented street flooding.
  • Retention basin: A related but distinct structure designed to hold a permanent pool of water in addition to detaining stormwater.
    • Unlike a detention basin, the retention basin always contains water.
Synonyms
  • Stormwater detention facility: A more formal term.
  • Flood control basin: Emphasizes the primary function of flood mitigation.
Related Phrases
  • "To detain water": The action performed by a detention basin.
    • The structure's function is to detain water temporarily.
  • "Peak flow control": A key purpose of detention basins.
    • The basin provides effective peak flow control for the watershed.
Related Concepts
  • Stormwater management: The broader field of practices, including the use of detention basins, to handle runoff.
  • Hydrology: The scientific study of the movement, distribution, and management of water on Earth, which includes the principles behind detention basin design.
