  1. PYFLOW_2.0. A new tool for estimating the impact parameters and the deposition rate and time of dilute PDCs based on field data

    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...

  2. ASHEE

    14 Aug 2015 | Contributor(s):: Matteo Cerminara, Tomaso Esposti Ongaro

    A fluid-dynamic model is developed to numerically simulate the non-equilibrium dynamics of polydisperse gas-particle mixtures forming volcanic plumes. Starting from the three-dimensional N-phase Eulerian transport equations for a mixture of gases and solid particles, we adopt an asymptotic...

  3. Numerical simulations (TOUGH2) to quantify crater lake seepage: a case study for Laguna Caliente, Poás Volcano (Costa Rica)

    23 Aug 2013 | Contributor(s):: massimo nespoli, micol todesco, dmitri rouwet, maurizio bonafede, raul mora-amador

    Volcanic lakes are different from the common reservoirs of meteoric origin because of the interaction with the hydrothermal system of the volcano. The hot fluids (gas + liquid) of volcanic origin rise through the bottom of the lake resulting in strong acidic water and a variable temperature...

  4. Observational constraints for lava flow models

    26 Jul 2013 | Contributor(s):: Einat Lev

    A presentation given at the IAVCEI 2013 workshop for benchmarking of mass flows. The presentation is focusing on natural and experimental observations relevant to benchmarking of lava flows: temperature, velocity and flux rate, material properties, crust cover,

  5. Running Puff from multiple different wind files

    19 Mar 2013 | Contributor(s):: Peter W Webley

    This is an example of how to run Puff from one wind field type and then restart from defined time interval with different NWP type.# First run off AVN-GFS# 24 hrs simulation with 1 hrly outputspuff -volc=Cleveland -eruptDate "2013 03 19 00:00" -model avn --plumeMin=0 --plumeMax=16000 -saveHours 1...

  7. Integrating numerical and laboratory models of explosive eruptions with field observations

    29 Jan 2011 | | Contributor(s):: Amanda Bachtell Clarke

    This lecture is part of the Large-scale Experiments Workshop held in September, 2010.
