HAPPENINGS Singapore
First site-specific study to commence for a flood-resilient master plan
The National Water Agency PUB will commence a site-specific study along Singapore’s City-East Coast, looking into possible solutions to protect it from the threat of rising seas caused by climate change. This is the first of a series of planned studies for different parts of Singapore’s coastline to be progressively carried out over the next few years, and are a key plank in Singapore’s long-term coastal protection plans.
The study covers 57.8 kilometres of the coastline, across three areas— Changi, the East Coast-Marina stretch and part of the Greater Southern Waterfront district. This section of the coastline had been identified to be more vulnerable and critical based on factors such as the potential impact of a flood event, criticality of assets (e.g., airports, economic and industrial districts) and opportunities to dovetail with upcoming developments.
The study will take around four years to complete, and will include work such as literature review for international best practices; collecting site data to support design works; formulating adaptation measures and pathways; and developing the designs of solutions to mitigate flood risks.
Hazel Khoo, Director of PUB’s Coastal Protection Department, said, “The real challenge is to develop solutions that are flexible and adaptive to climate change uncertainties, to safeguard our island and people from flooding risks while ensuring our coastlines remain liveable. This is also an opportunity for us to explore a combination of both engineering and nature-based solutions with innovative designs to better integrate with local development and land-use plans. This will allow us to potentially enhance the living environment and create new recreational spaces with multi-functional uses for the community like what was done at Marina Reservoir.”
Having divided Singapore’s coastline into different segments, PUB will adopt a phased approach to progressively roll out studies and develop protection measures for the respective segments of the coastline. Studies to protect Jurong Island and the North-West coast, comprising Sungei Kadut and Lim Chu Kang, will commence later this year and in 2022 respectively. The City-East Coast study will be undertaken by CPG Consultants Pte Ltd, a subsidiary of Singapore-based consultancy services, infrastructure and building management firm CPG Corporation. CPG was appointed following an open tender exercise in 2020. To augment its knowledge and capabilities in coastal protection and computer modelling, CPG will be partnering with Royal HaskoningDHV, a consultancy firm headquartered in the Netherlands that specialises in coastal engineering, as well as water management solutions provider Hydroinformatics Institute (H2i).
Building local expertise and engaging with stakeholders To enhance PUB’s knowledge and expertise in coastal engineering, the agency has formed a Coastal Protection Expert Panel, comprising both local and international experts in the relevant fields. The panel will share international best practices and planning considerations, and will provide advice that will allow PUB to build new capabilities and aid in its overall planning efforts.
The panel is chaired by Professor Chan Eng Soon, Chief Executive Officer of the Technology Centre for Offshore and Marine, Singapore (TCOMS). Panel members include coastal engineering experts such as Professor Marcel Stive, a Dutch engineer internationally recognised for his work in coastal solutions; Professor Robert Nicholls from the United Kingdom (UK), an expert in climate change and sea-level rise who was involved in the Building and Construction Authority’s Coastal Adaptation Study (2013- 2019); and Professor Robert Dalrymple from the US, who specialises in coastal processes. Professor David Balmforth, who is based in the UK and

an expert on urban flood risk assessment, rounds out the five-member panel.
Coastal protection is a complex and long-term undertaking. Besides consulting experts, PUB also intends to adopt a collaborative approach as they develop the strategies and solutions to protect Singapore’s coastlines. The agency will work closely with the community and relevant stakeholders, including nature groups and businesses, to seek their feedback on the proposed coastal protection measures and explore opportunities to create a vibrant living environment in harmony with nature.
