An innovative new flood forecasting tool for the safety of the people of New Caledonia.
Creation of a flood forecasting prototype for Grande Terre in New Caledonia as part of the PROTEGE project, funded by the 11th European Development Fund (EDF) regional.
New Caledonia faces significant flood risks associated with strong depression systems. It appeared essential to assess the feasibility of implementing a flood monitoring system in particularly vulnerable areas to enhance the intervention capabilities of emergency services during crisis periods.
The consulting firm BRL Ingenierie was commissioned, as part of the PROTEGE project and in collaboration with the National Institute for Agriculture, Food, and Environment (INRAE), to develop a flood forecasting prototype for Grande Terre in New Caledonia. This service is conducted in partnership with the Directorate of Civil Security and Risk Management (DSCGR), the Meteorological Service of New Caledonia, and the Government of New Caledonia (DAVAR).
The created tool enables real-time flood simulations based on precipitation and river flow data. Through the instrumentation of major rivers on Grande Terre and the use of rainfall observation data, the necessary modeling for flood prediction has been calibrated and tested.
The BRL Ingenierie provider was on a mission in New Caledonia for one week, from June 26th to June 30th, 2023. Throughout the week, meetings were held with various relevant government departments, as well as workshops to ensure that the tool is effectively integrated into their internal crisis management procedures. This mission also served as an opportunity to present the tool to decision-makers, outlining its advantages, limitations, and the necessary conditions for its optimal functioning.
