Performance of water sensitive urban design bioretention installations on the Gold Coast

Water Sensitive Urban Design (WSUD) techniques have been used for the last few decades to manage and treat stormwater runoff and protect urban infrastructure and aquatic ecosystems. Bioretention systems are one such technique that involve a depression or basin where stormwater collects and is then filtered through dense vegetation and a filtration layer reducing sediments and contaminants and slowly releasing runoff into stream systems. This research project proposes investigating existing bioretention systems on the Gold Coast to discover trends in design, construction and maintenance that are affecting their performance
