Consulting on flood risk management

Floods cause distress and damage wherever they happen and flooding from rivers, estuaries and the sea threatens many millions of people.Ramboll provides an integrated service in all aspects of flood risk management and design.

Ramboll’s flood risk management 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, man-made structures such as reservoirs, groundwater, 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 flood risks are understood, fully assessed and appropriately mitigated, and that the full potential of a site is maximised. Our clients include architects, developers, landscape architects, land owners, property managers, investors and insurers. We provide services to the government’s Environment Agency and to local authorities and county councils
