Cohesional behaviours in pyroclastic material and the implications for deposit architecture
Pyroclastic density currents (PDCs) are hazardous, multiphase currents of heterogeneous volcanic material and gas. Moisture (as liquid or gas) can...

Regulation effect of the grille spacing of a funnel-type grating water–sediment separation structure on the debris flow performance
The size of pores or the grille spacing of water–sediment separation structures directly affects their regulation effect on the debris flow...
