PYFLOW_2.0. A new tool for estimating the impact parameters and the deposition rate and time of dilute PDCs based on field data
out of 5 stars
22 Nov 2017 | Contributor(s):: Fabio Dioguardi, Daniela Mele, Pierfrancesco Dellino
PYFLOW_2.0 is a hazard tool for the calculation of the impact parameters of dilute pyroclastic density currents (DPDCs). DPDCs represent the dilute turbulent type of gravity flows that occur during explosive volcanic eruptions; their hazard is the result of their mobility and the capability...
Pyroclastic density currents and local topography as seen with the conveyer model
15 Apr 2014 | Contributor(s):: Domenico M. Doronzo
Pyroclastic density currents (PDCs) are multiphase flows generated during explosive volcanic eruptions, and they move down the volcano, and over the surrounding topography. The flow-topography interaction can play a fundamental role in the sedimentary processes, and in the resulting deposit...
