Bioretention is a water management practice that increasingly being applied for runoff quality control. Although previous studies have used some techniques to improve nutrient removal, nutrients still leach out. Therefore, this study Cascaded (CB) by connecting three columns in series. The planted Column was retrofitted adding subsurface drainage module (SDM) below the gravel layer create dual ...

Bioretention cells (BRCs) are a promising low-impact development (LID) practice that commonly used in urban settings to improve the water quality and mitigate hydrological effects of stormwater runoff. BRCs have been subject extensive research order better comprehend their function effectiveness. However, BRC performance differs greatly among regions terms hydrologic enhancement. Due this varia...
