Flood risk management services

About 40% of the world’s population lives within 100 km of the coast and it is estimated that 600 million people live on land lower than 10 m above sea level. With climate change and the increasing risk of major floods, it is vital that we prioritise cost-effective, low-carbon and sustainable flood defence and coastal erosion projects that protect communities from rivers and the sea. We find solutions that not only manage flood and coastal erosion risk but also maintain and enhance our current environment without compromising the ability of future generations to meet their needs.

Binnies is at the forefront of whole life-cycle delivery for flooding, coastal and maritime projects to ensure it delivers long-term sustainable outcomes. We adapt existing assets to mitigate the impacts of climate change and improve habitats while unlocking and redeveloping land for recreational, residential and commercial use. We offer stakeholder engagement services to ensure that our designs do not impinge on the natural environment and consider the needs and concerns of local communities.

In the UK and Ireland flood and coastal risk management sector, we work extensively for the Environment Agency, Natural Resources Wales, The Office of Public Works and local authority clients. We undertake feasibility studies to select optimum solutions; prepare business cases to unlock funding; design cost-efficient schemes using the latest digital technologies; provide construction supervision and administrative support; and advise on how to best manage and extend the life of our clients’ assets. Our team also has first-hand experience of supplementing and supporting client resources and helping them to manage their programme and deliver technical assurance on their behalf.

In the UK, we have a leading role in the £500 million River Thames Flood Alleviation Scheme. In addition to providing complex economic and engagement support and driving the sustainable management of natural resources, we undertook a natural capital valuation in which we identified an additional £48 million in ‘hidden’ economic benefits (health, water quality and carbon reduction) that were unlocked from the scheme’s nature recovery measures. We led a series of seven facilitated discussion workshops with more than 120 individuals representing a broad range of interests, including communities, cultural heritage and landscape, recreation, natural environment, business, landowners and project partners. We used the feedback to shape and agree the preferred solutions. The discussion group events have been professionally designed and facilitated in a deliberative process.

In Hong Kong, we undertook a feasibility study on enhancing the quality of coastal waters for the renowned Victoria Harbour, which involves the most extensive field survey and investigation programme of its kind ever undertaken in the city to support the government’s vision to transform the harbour into a water-friendly tourist hub.

In Singapore, we provided a more cost-effective alternative design to create a freshwater reservoir for the iconic Marina Barrage. While acting as a tidal barrier to prevent flooding, the barrage helps to boost freshwater resilience in the resource-scarce city state. The reservoir and its environment provide a beautiful venue for water-based and other recreational activities in the heart of the city.

The Binnies flood damage economic model (FDEM) is a tool we developed that is successfully used for flood damage calculations. It provides flexibility for assessing, visualising and understanding flood damage, and identifying the beneficiaries of flood defence schemes, as it uniquely bases all the calculations at property level. The tool supports improved decision-making, automated analysis and better optioneering.

Our international coastal and maritime team delivers both complex mooring and coastal protection solutions while providing environmental enhancements through the creation of new habitats. Our detailed design for the UK’s Donna Nook coastal realignment included new defences inland that were sympathetic to local features, which, after the breach in 2019, have been allowed to erode naturally and adapt over time. This provides an improved >1-in-200-year standard of flood protection and has created a habitat-rich mosaic of saltmarshes, mudflats and creeks. For other schemes, we have designed for tsunami level-scenarios and considered diverse projects, including floating gardens in the USA.

In Hong Kong, we have developed the innovative Yuen Long Barrage Scheme to deliver a broad range of benefits based on hydraulic performance, ease of operation and maintenance, constructability, cost and public disturbance. The scheme is designed with a stormwater conveyance capacity of 300 m3/s and includes a tidal barrier to combat extreme rainstorms and high tides. In addition to flood resilience, the scheme also provides opportunities for restoration of the river.
