Where are swales found?
More commonly referred to by laypeople as ditches or gutters, swales are often found along sloping driveways, adjacent to roads and parking areas, incorporated into golf courses, winding along the contours of hills on farms and in backyards, or along curbs to guide water away from roadways and into storm drains.
What are stormwater swales?
Swales, also known as bioretention, filter or infiltration strips, are broad, grass channels used to treat stormwater runoff. They direct and slow stormwater across grass or similar ground cover and through the soil. ... Some swales have liners to direct filtered runoff, or rocky linings to slow fast flows.
What are grass swales?
A grass drainage swale is an open channel that collects water from hard surfaces and allows it to percolate into the ground, reducing the amount of runoff leaving the road or property. The grass covering the side slopes and swale bottom provides a filtration surface for the water and helps to reduce the flow velocity.
What is a treatment swale?
Design Objective. Swales remove pollutants from stormwater by biofiltration, settling, and infiltration. Grassed. swales filter pollutants as stormwater runoff moves through the leaves and roots of the grass.
How do you make swales?
The general idea behind digging the swale is that it should be about three-times as wide as it is deep, and the berm—the pile of excavated dirt—should be mounded to create the upper part of the bottom side of the swale. Make sure that the base of the swale is level so that the water disperses evenly.
Why are swales used?
Description. Swales are shallow, broad and vegetated channels designed to store and/or convey runoff and remove pollutants. They may be used as conveyance structures to pass the runoff to the next stage of the treatment train and can be designed to promote infiltration where soil and groundwater conditions allow.
What's the definition of swales?
Definition of swale
: a low-lying or depressed and often wet stretch of land also : a shallow depression on a golf course.
What is a swale in civil engineering?
A swale is a shady spot, or a sunken or marshy place. In particular, in US usage, it is a shallow channel with gently sloping sides. ... Artificial swales are often infiltration basins, designed to manage water runoff, filter pollutants, and increase rainwater infiltration – green instances are the subterm bioswales.
Are swales bad?
Swales without trees can possibly be even more damaging than the flow of water they have pacified. In some climates, they can potentially oversaturate the landscape, leaving a designer with difficult growing conditions.
How do swales work?
Swales follow the contours around the base of a natural or created slope, redirecting storm water and filtering runoff as it sinks into the soil, instead of keeping it in one place, like a rain garden. Plants suck up the water along a swale's gently sloping banks and sometimes down the center of the channel.
Are swales suds?
Swales and filter strips are source control elements of SUDS. They are simple and yet are very effective in managing surface water runoff. The grass or other vegetation slows water down and also traps some of it by allowing it to soak into the ground.
Are swales lined?
Swales are linear grass covered depressions which lead surface water overland from the drained surface to a storage or discharge system, typically using road verges. ... The underlying aquifer can be protected, if needed, by placing an impermeable lining under the swale below the soil.
