Stormwater flows are a major issue for urban areas where impervious surfaces (e.g., roads) limit stormwater infiltration, thus increasing the risk for flooding. When stormwater-associated pollutants are discharged in aquatic resources (e.g., rivers, lakes), stormwater flows also threaten the health of aquatic ecosystems. To reduce these risks, bioretention cells can be used to intercept and reduced contaminated flows. These stormwater control measures include an engineered soil media whose properties influence infiltration and pollutant removal.

雨水流动是城市地区的一个主要问题，在城市地区，不透水的表面（例如，道路）限制了雨水的渗透，从而增加了洪水的风险。当与雨水相关的污染物排放到水生资源中时（例如，河流、湖泊），暴雨水流也威胁着水生生态系统的健康。为了降低这些风险，可以使用生物滞留细胞来拦截和减少污染流。这些雨水控制措施包括工程土壤介质，其特性影响渗透和污染物去除。
