A bioswale is a landscape feature designed to capture and filter stormwater runoff by channeling it through a shallow, vegetated trench or depression. Bioswales help reduce flooding, remove pollutants from the water, and allow for the natural infiltration of water into the soil. They are commonly used in urban areas, parking lots, and along roadsides to manage runoff and improve water quality. The plants and soil in a bioswale act as natural filters, trapping sediments and absorbing excess nutrients.
