This archetypal form of swale is a dug-out, sloped, often grassed or reeded "ditch" or "lull" in the landform. One option involves piling the soil onto a new bank on the still lower slope, in which case a bund or berm is formed, mitigating the natural (and often hardscape-increased ) risks to slopes below and to any linked watercourse from ...
[2]: 19 Bioswale design is intended to safely maximize the time water spends in the swale, which aids the collection and removal of pollutants, silt and debris. Depending on the site topography, the bioswale channel may be straight or meander.
An interceptor drainage swale in the middle of the berm is also helpful or the back of the berm can be terraced with retaining walls. On sloping sites, runoff may cause problems. A drainage swale or gully can be built to divert water around the house, or a gravel-filled trench with a drain tile can be installed along with footing drains.
Comparison of a ha-ha (top) and a regular wall (bottom). Both walls prevent access, but one does not block the view looking outward. A ha-ha (French: hâ-hâ [a a] ⓘ or saut de loup [so də lu] ⓘ), also known as a sunk fence, blind fence, ditch and fence, deer wall, or foss, is a recessed landscape design element that creates a vertical barrier (particularly on one side) while preserving ...
To function properly, a trench must be designed with a pretreatment structure such as a grass channel or swale, in order to capture sediment and avoid clogging the trench. [4] It may not be appropriate for sites where there is a possibility of groundwater contamination, or where there is soil with a high clay content that could clog the trench. [5]
"There's levels to tattling. Sometimes it's something as little as 'So and so is copying me,' or 'So and so keeps looking at me,' And those don't need to cause an interruption.
The family of an American killed when a Malaysian Airlines plane was shot down over Ukraine in 2014 can sue Russia's largest bank for allegedly providing money transfers to a group blamed for ...
A dry well receives water from entry pipes at its top. It can be used part of a broader stormwater drainage network or on smaller scales such as collecting stormwater from building roofs. It is used in conjunction with pretreatment measures such as bioswales or sediment chambers to prevent groundwater contamination. [6] [2]
