Debris flows are unpredictable phenomena that behave like liquids during movement but can deposit like solids. The document outlines Carlo Gregoretti's presentation on debris flows at Mekelle University, including an introduction to debris flows, their unpredictability, modeling their rheology and wave behavior, reliability of simulation models, hydrological modeling of headwater basins, triggering models, deposition areas, hydraulic routing models, comparing models to field observations, new trends in rheology modeling, and precipitation triggering of debris flows.
