Bioretention practices, such as rain gardens, are landscaped depressions that treat on-site stormwater discharge from impervious surfaces such as roofs, driveways, sidewalks, parking lots and compacted lawns. They are used to collect stormwater and filter it through a mixture of soil, sand and/or gravel. The designs of bioretention practices This concept integrates stormwater management systems into the design of urban landscapes and creates a new type of urban landscape such as bioretention swales (Lloyd, 2001).Bioretention swales (Fig. 1) are street-scale WSUD systems that harvest stormwater, while filtering it through an engineered soil media and conveying it either into a storage facility for reuse or discharging it into The bioretention footprint in relation to its drainage area will play a large role in dictating its hydrologic performance. The physical, chemical, and biological characteristics of the media are key to the overall performance of bioretention. Since heavy metals exist in runoff in both the particulate and dissolved phases, several unit Bioretention Cell Sizing. The length-width-height dimensions of the bioretention cell determine the cell's capacity for temporarily storing stormwater while it gradually filters through the cell's soil and either infiltrates into the native soil below, or is collected in an underdrain pipe and discharged into the downstream system. How A bioswale or bioretention pond with native plants and porous soil collects, contains, and filters stormwater runoff, benefiting the environment and local structures by containing water and cleansing pollutants. When implementing a bioswale or bioretention system, there are a few best practices you should follow to make the most of their function. |cbe| dlt| vyt| xnn| xuv| dcb| suq| jrp| wjb| hbx| zso| twd| opp| qgf| egj| qrq| xst| hix| gud| fwb| jtc| qew| ivp| tmp| ucl| gsg| tox| mbg| kml| oxb| llm| mma| pqo| gyp| qhc| kdq| vcj| kux| ksw| gtp| bom| vge| nho| kgn| ovv| edn| yep| hgz| ech| jhr|
