Abstract:
To predict flood and debris flow dynamics a numerical model ,based on 1D De Saint Venant equations ,modified for including erosion / deposition processes along the path ,was developed.To better predict immature ( stratified ) flows ,the model was improved in order to feature ,in a more realistic way,the distribution of the particles of different size within the mixture .The model is feasible to predict the whole debris flow phenomenon , i. e. the triggering ,mobilising and stopping processes of both mature and immature debris flow in different dam-break contitions.
