This paper refers on SPH simulations of water and non-cohesive sediment scour flow in a laboratory flume schematizing a two-dimensional vertical cross-section of a reservoir, in the presence of deposited sediment bed, during dam bottom outlet opening maneuvers . In order to capture the scour phenomenon a model suitable for the treatment of granular material is implemented. Experimental data of sediment bed profile are then compared to results of SPH simulation, and discussed to focus on capabilities and limits of the proposed model.

Abstract
This paper refers on SPH simulations of water and non-cohesive sediment scour flow in a laboratory flume schematizing a two-dimensional vertical cross-section of a reservoir, in the presence of deposited sediment bed, during dam bottom outlet opening maneuvers . In order to capture the scour phenomenon a model suitable for the treatment of granular material is implemented. Experimental data of sediment bed profile are then compared to results of SPH simulation, and discussed to focus on capabilities and limits of the proposed model.File in questo prodotto:
