A French drain is a trench that diverts water away from an area where it's pooling to a lower elevation where it can be released, explains Mike Arnold, director of The Gardens at Texas A&M ...
A diagram of a traditional French drain. A French drain [1] (also known by other names including trench drain, blind drain, [1] rubble drain, [1] and rock drain [1]) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area.
A streambed or stream bed is the bottom of a stream or river and is confined within a channel, or the banks of the waterway. [1] Usually, the bed does not contain terrestrial (land) vegetation and instead supports different types of aquatic vegetation ( aquatic plant ), depending on the type of streambed material and water velocity.
Drainage basin (also known as a watershed in the United States) The area of land where water flows into a stream. A large drainage basin such as the Amazon River contains many smaller drainage basins. [34] Floodplain Lands adjacent to the stream that are subject to flooding when a stream overflows its banks. [34] Headwaters or source
Trench drains are commonly confused with French drains, which consist of a perforated pipe that is buried in a gravel bed, and which are used to evacuate ground water. A slot drain , also wrongly associated with a trench drain, consists of a drainage pipe with a thin neck (or slot) that opens at the ground surface with sufficient opening to ...
A percolation trench is similar to a dry well, which is typically an excavated hole filled with gravel. [3] Another similar drainage structure is a French drain , which directs water away from a building foundation , but is usually not designed to protect water quality.
The creek that may have run along the bottom of the gulch in the past has been diverted to a parallel aryk. A gulch is a deep V-shaped valley formed by erosion. It may contain a small stream or dry creek bed and is usually larger in size than a gully. [1] Sudden intense rainfall upstream may produce flash floods in the bed of the gulch.
A dry lake bed, also known as a playa (/ ˈ p l aɪ-ə /), is a basin or depression that formerly contained a standing surface water body, which disappears when evaporation processes exceed recharge. If the floor of a dry lake is covered by deposits of alkaline compounds, it is known as an alkali flat.
