Introduction
Retention basin is an artificial pond. Landscaping is provided along the edge of the pond. There is constant water in the retention basin. Its primary purpose is to control storm water runoff, prevent flooding, control erosive forces, create an artificial wetland, and enhance water quality in nearby bodies of water. It is also called as stormwater retention basin.
Description Of Retention Basin
Wet ponds are widely utilized to reduce flooding risk, recharge groundwater, and improve water quality. Sometimes they replace the forest’s or another natural process’s natural absorption, which is lost when an area is developed.
Rainfall spends less time on impermeable surfaces before it enters the stormwater drainage system. This will result in extensive flooding downstream if it is not stopped.
A stormwater pond’s purpose is to hold this surge in place and let it out gradually. The quantity and intensity of storm-induced floods on receiving waters downstream are reduced by this gradual release.
Stormwater ponds also gather suspended sediments, which are frequently present in stormwater at high quantities as a result of upstream development and the application of sand to roads.
Design Consideration For Retention Basin
Storm water typically flows into reservoirs drainage system. Reservoirs are designed in a way that they can bear high water pressure. These types of water channels are restricted in drainage to the receiving area by outlet structures that only function during very large storms.
Regulating ponds are often landscaped with a variety of grasses, shrubs, and aquatic plants to provide embankment stability and aesthetic benefits. Vegetation also provides water quality benefits by removing soluble nutrients through uptake.
Correct reservoir depth is critical for contaminant removal and maintenance of fish populations. Urban fishing continues to be one of the fastest growing fishing segments as new suburban neighborhoods are being built around these bodies of water.
Uses Of Retention Basin
- Retention basins are used to collect flood water.
- It decrease the chances of flood.
- Retention basis are good for economy. Various types of fishes can be produce in the retention basin.
