Dry pond on brook to reduce floods, near Děčín, Czech Republic. A detention basin or retarding basin is an excavated area installed on, or adjacent to, tributaries of rivers, streams, lakes or bays to protect against flooding and, in some cases, downstream erosion by storing water for a limited period of time.
It is distinguished from a detention basin, sometimes called a "dry pond", which temporarily stores water after a storm, but eventually empties out at a controlled rate to a downstream water body. It also differs from an infiltration basin which is designed to direct stormwater to groundwater through permeable soils.
A detention dam is a dam built to catch surface runoff and stream water flow to regulate the water flow in areas below the dam. [1] Detention dams are commonly used to reduce the damage caused by flooding or to manage the flow rate through a channel. [2] Detention dams can also be constructed to replenish groundwater and trap sediment. [2]
Recently completed infiltration basin for stormwater collection. An infiltration basin (or recharge basin) is a form of engineered sump [1] or percolation pond [2] that is used to manage stormwater runoff, prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay.
Vernal pools, also called vernal ponds or ephemeral pools, are seasonal pools of water that provide habitat for distinctive plants and animals. They are considered to be a distinctive type of wetland usually devoid of fish, and thus allow the safe development of natal amphibian and insect species unable to withstand competition or predation by ...
Builders filled in the pond and built homes on the land without notifying the buyers. After exploring all the options, the town of Johnstown has been forced to buy back the four homes, demolish ...
In a complex arrangement, Slattery gave up a portfolio of 14 immigration detention facilities and adult prisons across the country as part of a $62 million sale, while buying back one division for $3.75 million: Youth Services International. As this new Slattery venture continued to grow in Florida, the old problems surfaced again.
A stormwater detention vault is an underground structure designed to manage excess stormwater runoff on a developed site, often in an urban setting. This type of best management practice may be selected when there is insufficient space on the site to infiltrate the runoff or build a surface facility such as a detention basin or retention basin .
