Experimental Analysis of Velocity Distribution in a Coarse-Grained Debris Flow: A Modified Bagnold’s Equation

Today, Bagnold&rsquo

STIMA DEI PROFILI DI VELOCITA’ DEI FLUSSI IPERCONCENTRATI: analisi di sensitività sui parametri dell’equazione di Bagnold.

Nel presente lavoro l'attenzione è focalizzata sulla dinamica di propagazione delle colate detritiche, fenomeni naturali di elevata pericolosità e forza distruttiva. Com’è noto, una colata detritica si verifica quando il materiale solido (sedimenti e materiale sciolto) di versanti caratterizzati da elevate pendenze viene destabilizzato dal deflusso di ingente volume d’acqua. Durante la propagazione della miscela acqua-sedimento, elementi anche di elevata dimensione (massi, alberi,..) possono essere mobilitati aumentando la forza distruttiva della colata con conseguenti possibili ingenti danni a edifici e infrastrutture, perdita di vite umane e ostruzioni (parziali o totali) dei corsi d’acqu…
