Floods are the most common natural disasters in Asia, and the urbanised mega-deltas in the region are experiencing increased incidence of flooding. Flood risk has increased due to rapid urban growth which makes people more vulnerable and threatens economic assets, and due to climatic extremes, such as frequent and intense typhoons, rainstorms and global sea-level rise. This study addresses the Pearl River Delta (PRO), where 120 million people will live by 2050, and in particular the megacities of Hong Kong and Shenzhen, important economic hubs of East Asia, which are low-lying, densely populated and increasingly vulnerable to flooding. The research has focussed on case studies of Tai 0 and the Shen- zhen River catchment to address both coastal and riverine flooding. Drawing on best practice and lessons from flood risk management internationally, a theoretical sustainable flood risk appraisal (SF RA) framework was developed to enable bench marking of flood management practices, constraints and barriers against sustainability objectives for the two study sites, and for the wider PRO region. A textural analysis approach is employed in order to analysis data from semi-structure interviews, and secondary source from grey literature. The study found good practice in the area, including that authorities initiated more ecological friendly soft engineering approaches in the current Shenzhen River Regulation project, and flood contingency planning and a special tidal warning system are operational in Tai 0 after two coastal floods. However, current practices are rather ad-hoc, and tend to respond to events without sufficient prior strategic and long term planning strategies. They also suffer from a lack of attention to socio-economic risks, flood risk information is not publicly accessible so limiting flood awareness and preparation, and access to flood insurance is poor. Traditional hard-engineering measures still dominate. Significant constraints on sustainable flood risk management (SFRM) practice also include poorly defined Institutional responsibilities with respect to flood risk management (FRM) and climate change adaptation, and little opportunity for public participation in flood risk management.
