On account of its economic weight, its dense network of businesses and research centres and its appeal for tourists, Greater Paris is one of the world’s major metropolitan regions.
Floods and natural hazards
Artelia was a pioneer in the detailed mathematical modelling of floods in urban areas and has designed innumerable protection schemes. It has also specialised in assessing and reducing the vulnerability of public or private assets and implementing risk mitigation measures, concerning critically important urban areas and industrial sites in particular.
Artelia is frequently involved in the drawing up of flood risk assessments, prevention and disaster contingency plans and cost-benefit analyses of risk reduction measures. It also helps to set up flood warning, flood forecasting, alarm and crisis management systems as well as resilience measures in urban areas. Artelia is a major innovator in these fields.
Artelia has been accredited by the French Ministry of Ecology, Sustainable Development and Transport to perform safety studies of hydraulic structures. This accreditation, to perform monitoring on embankments and dams, attests to the skills and dedication of the teams working daily alongside operators, especially on nearly 40 class A or B large dams owned by Electricité de France. Numerous hydrological and dam break wave studies have also been performed in order to prevent risks related to managing these major structures.
The programme to mitigate urban risks in Haiti involves implementing a standard national methodology, raising the capacity of national and local authorities, improving knowledge and maps representing risks, and drawing up risk prevention plans for the most vulnerable urban areas.
The project consists in creating a modern hydraulic modelling tool for the main water courses in the Seine river basin.
The section of the future high-speed rail line passing through the town of Saint-Jean-de-Maurienne is liable to be flooded in the event of a breach on the embankments that protect it.
