Developing a holistic risk management plan in mitigating flooding risks for buildings adjacent to the Swan River in Perth, Western Australia

摘要

Climate change as a major issue in the 21st century has seen the rise of the sea level and worse storm surges. This has impacted on the further distribution of salinity and flooding of low laying areas even in further inland areas. As the consequence, buildings in the proximity of riverbanks are left susceptible to potential damages and shortened life cycles. Thus, there is a real need to change the way buildings in these areas to be designed and how risk of damages can be mitigated and managed. The city of Perth in Western Australia, like many other cities around the world, is laying on the riverbank of a large river, the Swan River. As the population of Perth increases dramatically, it will become important to ensure sustainability of its buildings to support the ever growing populations and hence its needs. There are myriads of approaches in mitigating and managing these risks. This research project aims to investigate the contemporary risk management practices in mitigating flooding risk in buildings adjacent to the Swan River and bring them together as a holistic risk management approach. The findings of this research can be proposed to the Western Australian government to assist them in developing further policies in ensuring sustainable buildings fit for the future. At this point of writing, the research project is on its early stage of conducting literature review and designing the research methodology. It is intended to conduct a pilot survey, followed by case study approach of contemporary buildings adjacent to the Swan River to contextualize the research. This paper presents the current progress of this research.
