What Is Detention Basin?
Detention basin is a empty excavated area near water bodies such as rivers, lakes and streams. It is also called retarding basin.
These basins mostly remain dry. When it rains heavily, the basin get filled with water. Detention basins reduce the potential for flooding of surrounding areas.
The detention basin is an empty pond. A basin that holds water permanently is called a retention basin. Detention basins are simple excavated areas to hold water. Some modern detention basins are designed to maintain water quality.
Description
Detention basins are very useful for controlling minor and major floods. Valleys are created when a city develops. Ponds help manage excess urban runoff caused by newly constructed enclosed surfaces such as roads, parking lots and roofs.
The main feature of a detention basin is that it accepts a large inflow of water, but restricts the outflow by providing a small opening at the lowest point of the structure. The size of this opening is determined by the capacity of the underground and downstream culverts. Flow areas are often designed to prevent any damage to the structure.
Reservoirs constructed with real-time controlled discharge from ponds are highly effective in retaining total suspended solids and related pollutants such as heavy metals as compared to uncontrolled reservoirs.
FAQ
What Is The Difference Between Retention Basin And Detention Basin?
The main difference between retention basin and detention basin is that retention basin is a permanent water body while detention basin is a dry pond. Detention basin only collect water if there is high rainfall.
