The document summarizes the second seminar of the CLIMAWARE project. It discusses granular flow extremes like floods, sediment transport, debris flows, and avalanches. The project is studying the impacts of climate change on water resources and hydrogeological risks. It uses experimental approaches with laboratory and scale models to develop predictive tools for simulating extreme events under changing climate scenarios.
