IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Investigations on the drag force in submerged granular flows
Author : ARONNE ARMANINI(1), ELENA NUCCI(2) & MICHELE LARCHER(3)
ABSTRACT
The rheology of submerged granular flows is described according to a heuristic model recently proposed by Armanini
et al. (2014), which is a single parameter model, based on the fundamental evidence that the collisional and the frictional
regimes coexist across the flow depth. The main novelty of the heuristic model is to provide an equation of state valid
also for the frictional regime. Investigations on the role of the drag force in the balances of uniform submerged granular
flows are presented. A new relation of the voidage function valid for all the values of concentration is derived.
