Various pollutants generated and deposited in the urban regions are washed-off to the receiving waters during storm events, resulting in receiving water quality degradation. The impacts on receiving water quality degradation include elevated toxicity, algal blooms and excessive sedimentation. Thus, use of stormwater pollution mitigation strategies to improve the quality of receiving waters has become increasingly important. Water sensitive urban design (WSUD) is the stormwater management philosophy adopted in Australia. The aims of WSUD are to manage stormwater quality and quantity to minimise the impacts of urban developments on the surrounding environment (Lloyd et al., 2002). WSUD concepts are developed to provide technically effective, more economical and less environmentally damaging solutions for stormwater management. However, there are barriers in widespread implementation of WSUD. In this regard, the long-term viability of implemented WSUD systems are perceived with high level of importance (Lloyd et al., 2002). The primary concern is that the treatment systems adopted in WSUD approach are typically designed considering static climate conditions. Changing climate in future scenarios including changes to rainfall patterns and characteristics of dry periods can reduce the effectiveness of such WSUD systems (Beecham et al., 2012). Climate change would have a significant impact on the future functionality of WSUD. Researchers commonly agree that
