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 and cross discipline approach, involving many sectors, such as transport, energy, critical infrastructure, urban development and environment.

Ramboll is among the world’s leading consultants, offering everything from large to small scale planning and implementation services for climate adaptation and flood risk management. We help our customers identify the challenges, quantify financial implications of climate change, and find alternative solutions for the consequences – mitigation as well as adaptation focusing on enhancing multi-benefits. We serve both the public and private sectors, at national, regional and local levels.

Integrated services

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 with insufficient capacity.

These challenges call for implementation of adaptive measures in coastal zone management, river basin management, water supply, and storm- and wastewater management, to name just a few. Our experience in hydraulic modelling and risk assessment of flooding from the sea, 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. Investments in climate-adapted buildings and infrastructure can not only help to safeguard standards of living but can also avoid undesirable human and material losses from extreme weather and flooding.

Feature article about Denmark's climate change adaptation

From August 2010 to August 2011, the City of Copenhagen—the capital of Denmark—was hit by three devastating cloudbursts in a 12-month period. As a consequence, the city decided it had to do something to protect the city from future damage.

On 2 July, 2011 large areas of the city of Copenhagen were flooded. Copenhagen is on the front line of climate change, experiencing increasingly heavy rain events, as they are also on the leading edge of urban innovation with a vision of transforming their city into a sustainable, C02 neutral city by 2025.

Bishan-Ang Mo Kio Park

Bishan Park is one of the most popular parks in the heartlands of Singapore. As part of a much-needed park upgrade and plans to improve the capacity of the Kallang channel along the edge of the park, works were carried out simultaneously to transform the utilitarian concrete channel into a naturalised river.
