Le 15 octobre prochain, Roberta RAVANELLI nous fera le plaisir d’exposer ses activités de recherches scientifiques. Roberta RAVANELLI vient d’être nommée chargée de cours au Département de Géographie (Géomatique).
Elle fera cet exposé en anglais et nous aurons l’occasion de discuter avec elle, certainement en français aussi, après cet exposé sur son intégration dans l’équipe du Département.
Résumé :
Surface freshwater plays a vital role in sustaining life on Earth and supporting socio-economic activities. Its availability influences ecosystems, hydrology, and climate, while providing essential water resources for urban, agricultural, and industrial uses. In this context, inland water bodies and glaciers are critical to climate resilience and sustainable water resource management.
This talk presents recent advances in the use of Earth Observation data—specifically from the GEDI (Global Ecosystem Dynamics Investigation) and SWOT (Surface Water and Ocean Topography) altimetry missions—for monitoring inland water surface levels and Alpine surface glacier elevations through a geospatial big data analysis approach. The focus will be on presenting robust analysis workflows that enable the investigation of temporal dynamics in surface water levels and glacier elevations. These efforts aim to support global monitoring objectives aligned with the UN Sustainable Development Goals — specifically Goal 6 (Clean Water and Sanitation) and Goal 13 (Climate Action) — by addressing the growing need for large-scale and continuous environmental monitoring.
