2. Bioswale - Wikipedia

   en.wikipedia.org/wiki/Bioswale

   They consist of a swaled drainage course with gently sloped sides (less than 6%). [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.

3. Swale (landform) - Wikipedia

   en.wikipedia.org/wiki/Swale_(landform)

   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 ...

   Photos of the gardens as well as design documents and drainage calculations are available online. [41] The Washtenaw County Water Resource Commissioner's office also offers yearly in person and online Master Rain Gardener classes to help guide those interested in the rain garden design, building, and upkeep process.

5. Keyline design - Wikipedia

   en.wikipedia.org/wiki/Keyline_design

   Keyline design is a landscaping technique of maximizing the beneficial use of the water resources of a tract of land. The "keyline" is a specific topographic feature related to the natural flow of water on the tract. Keyline design is a system of principles and techniques of developing rural and urban landscapes to optimize use of their water ...

7. Bioretention - Wikipedia

   en.wikipedia.org/wiki/Bioretention

   In laboratory experiments, bioretention cells removed 94%, 88%, 95%, and >95% of zinc, copper, lead, and cadmium, respectively from water with metal concentrations typical of stormwater runoff. While this is a great benefit for water quality improvement, bioretention systems have a finite capacity for heavy metal removal.
