Climate Adaptation & Flood Risk Management

The present situation requires adaptation to the inevitable impacts of climate change. Both mitigation of and adaption to climate change call for a holistic, cross-boundary, cross discipline approach, involving many sectors, such as transport, energy, infrastructure, urban development and natural resource use, together with protection of natural systems and the wider environment.

Ramboll is among the world’s leading consultants, offering planning and implementation services for climate adaptation and flood risk management. We serve both the public and private sectors, at national, regional and local levels. We help our customers quantify the financial implications of climate change, and find alternative solutions for the consequences – mitigation as well as adaptation.

Adapting to Climate Change

It is generally accepted that global warming will lead to a rise in global sea level, increasing the risk of flooding in low-lying, coastal regions. An increase in the frequency and severity of extreme weather patterns will further increase this risk, contributing to flooding from rivers and from urban drainage systems of insufficient capacity.

These challenges call for adaptive measures in river basin management, water supply, storm- and wastewater management and agriculture, to name just a few. Our experience in modelling and risk assessment of flooding from the sea, from rivers and drainage systems allows our customers to make informed decisions about future investments. Environmentally and financially sustainable solutions rely on an evaluation of flood risk and costs for climate adaptation. Investment in climate-adapted buildings and infrastructure can help to safeguard standards of living and can avoid undesirable human and material costs from extreme weather and flooding.

Flood risk management

Ramboll provides an integrated service in all aspects of flood risk management and design. Our highly experienced engineers and scientists provide innovative, robust solutions to the challenges posed by river and surface water management, and can successfully steer projects through planning and regulatory requirements.

We help our clients mastermind their planning to satisfy the EU Floods Directive and quantify their risk and exposure to flooding. We offer innovative, cost-effective solutions for these and other climate change-related challenges.

An integrated service

Ramboll's flood risk management and climate adaptation teams offer high quality integrated services for all stages of a project — from initial studies and options appraisals to cost-effective design solutions, regulatory approvals and ongoing assessment after completion. We assess flooding potential from all sources, including coastal waters, rivers, surface water, groundwater, and man-made structures such as reservoirs, overland flow, site drainage and public sewers.

Our engineers have an in-depth understanding of how flooding can affect a development and we clearly communicate flood risks to clients and project design team members. This ensures that, in close cooperation with our landscape architects, traffic planners, road and tunnel engineers, biologists, geologists, geographers, economists  etc.,  flood risks are understood, fully assessed and appropriately mitigated, and that the full potential of a site is maximized.

Our clients include cities, utility companies, developers, private land owners, property managers, investors and insurers. We provide services to government's Environment Agencies and to local authorities and county councils.
