Floods and natural hazards

Flooding is a major threat to humans and infrastructure. Numerous studies have been devoted to floods, so that it is now possible anticipate them with greater certainty, take protection measures and manage crisis situations more effectively. Artelia was a pioneer in the detailed mathematical modelling of floods in urban areas and has designed innumerable protection schemes. It has extended these services to the areas of prevention and evaluation of the vulnerability of public and private property, and implementing structural and non-structural risk-reduction measures. It is frequently involved in the introduction of flood-risk prevention and disaster contingency plans and helps to set up flood warning, flood forecasting, alarm and disaster management systems as well as resilience measures in urban areas. Artelia is a major innovator in these fields.
