Analyzing the Impact of Sea Level Rise on an Urbanized Coastal Area: Saint-Laurent-du-Var

25/06/2025

The MedSeaRise project supports Mediterranean coastal territories in understanding and preparing for the long-term effects of sea level rise. A key objective of the project is to develop a methodology that allows stakeholders or experts to assess risks and to amplify their knowledge on adaptation strategies using existing and projected datasets.
As part of this mission, the Chamber of Commerce and Industry would like to work on Saint-Laurent-du-Var, located just next to Nice. A part of this city is a coastal area with a high level of urbanization, combining important economic infrastructures and coastal activities that could be exposed to environmental risks.
🏙️ The selected site includes:
A major commercial center (Cap 3000), employing over 2000 people
Recreational facilities along the coastline (Promenade des Flots Bleus), Cousteau & Landberg beaches
Proximity to the Var River delta, which brings specific hydrological challenges, with an accretion phenomenon
The site has already been subject to preliminary studies related to coastal defence infrastructure, but this new MedSeaRise case study will take a longer-term approach, focusing on future climate scenarios and impacts such as:
🌊 Marine submersion caused by extreme weather events and sea level rise
🏚️ Economic vulnerability, measured by potential flooded area or damage to buildings
💧 If relevant, saltwater intrusion and its possible effects on soils or groundwater systems
The analysis relies on datasets collected and simulated by MedSeaRise’s European scientific partners, including projections of sea level anomalies, temperature, precipitation, and astronomical tidal variations.
By refining the zoning of the study area and integrating high-resolution topographic and hydrodynamic models, this work will contribute to identifying vulnerable subzones and establish the best impact indicators.
✅ The next steps will involve defining the precise scope of the study, with results expected to enrich the incoming benchmarks.
