A constructed swale or bioswale built in a residential area to manage stormwater runoff. A swale is a shady spot, or a sunken or marshy place. [1] In US usage in particular, it is a shallow channel with gently sloping sides.
Annual maintenance through soil testing, visual inspection, and mechanical testing is also crucial to the health of a bioswale. Bioswales are commonly applied along streets and around parking lots , where substantial automotive pollution settles on the pavement and is flushed by the first instance of rain, known as the first flush .
Landscape maintenance (or groundskeeping) is the art and vocation of keeping a landscape healthy, clean, safe and attractive, typically in a garden, yard, park, institutional setting or estate.
Properties that are influenced by soil texture include porosity, permeability, infiltration, shrink-swell rate, water-holding capacity, and susceptibility to erosion. In the illustrated USDA textural classification triangle, the only soil in which neither sand, silt nor clay predominates is called loam.
Swelling of marine clay has the potential to destroy building foundations in only a few years. Due to the changes in climatic conditions on the construction site, the pavement constructed on the marine clay (as subgrade) will have less durability and requires lot of maintenance cost.
The shrink–swell capacity of soils refers to the extent certain clay minerals will expand when wet and retract when dry. Soil with a high shrink–swell capacity is problematic and is known as shrink–swell soil, or expansive soil . [ 1 ]
