Debris flow: Simulating the mitigation properties of vegetation

Author:

Leonardi Alessandro,Pasqua Andrea,Flammini Luca,Pirulli Marina

Abstract

Natural vegetation impacted by debris flows can act as an energy dissipator. This braking effect is similar to the one exerted by baffle arrays. However, this effect, and its potential for hazard mitigation, has been studied only marginally. In this work, we apply a depth-averaged model to reproduce scaled laboratory experiments of flow-forest interaction.
