Themethodology consists in the installation of observatories on the dynamics of sandy beaches in differentmorphological and sedimentary contexts. A “state zero” is established from a combination of satellite imagery,low altitude digital imagery and topographic and hydrodynamic measurements. These measurements arereiterated after an extreme event in order to apprehend the importance of morphological change, impactdampening and recovery. The monitoring is then continued over regular intervals with the aim of determiningrates of morphological and sediment budget recovery until equilibrium is restored.This experimental network design will subsequently be extended to other tropical beaches located on thepropagation paths of cyclones.Lire moins >
