Coastal flood risk: improving operational response, a case study on the municipality of Leucate, Languedoc, France
Abstract Background Climate change and rising sea level will certainly lead to significant changes in the management of low-lying coastal areas in the coming decades. While the most recent studies in the field of coastal storms-related flooding are increasingly integrated, simultaneously addressing...
