The pyroclastic flow is treated as a two-c … The pyroclastic flow is treated as a two-component granular flow with >30% volume fraction of solids supported by excess pore fluid pressure in a laminar Newtonian fluid. This approach of modeling mass flows is adapted from the debris flow model of Iverson and Denlinger (2001). The model solves depth averaged mass and momentum conservation equations in 2D, with suitable source terms, to determine the thickness and velocity of the current at each point in time and space. The current is primarily driven by gravity and the motion of the current is opposed by friction and viscous resistance. A shear-rate dependent variable basal friction model is used to determine the basal friction as the flow evolves (Jop et al., 2006). A 1st order Godunov scheme with an HLLC Riemann solver is used to calculate the flux across cell interfaces (Toro, 2009) and the source terms are solved separately using an explicit Euler method.ed separately using an explicit Euler method. +

The model generates several georeferenced … The model generates several georeferenced tiff files upon completion. These geotiff files can be viewed using any GIS software. Each file is a 2D map of a modeled flow property such as thickness, velocity etc. Additionally, multiband geotiff files containing similar 2D maps at multiple user-defined time intervals during the simulation.</br></br>Depth – Map of the final 2D flow thickness (in meters).</br></br>Depthbin – Binary map where cells with thickness > user-defined threshold thickness have a value of 1 and the rest of the cells have a value of 0.</br></br>MaxDepth – Map of the maximum flow depth obtained at each cell during the entire simulation (in meters).</br></br>MaxVelocity – Map of the maximum velocity obtained at each cell during the entire simulation (in m/s).</br></br>MomentumX – Map of final 2D flow momentum along the X direction (in sq. m/s).</br></br>MomentumY – Map of final 2D flow momentum along the Y direction (in sq. m/s).</br></br>Velocity – Map of the final 2D flow velocity (in m/s).</br></br>VelocityX – Map of the final 2D flow velocity along the X direction (in m/s).</br></br>VelocityY – Map of the final 2D flow velocity along the Y direction (in m/s).</br></br></br>The multiband (movie) files output by the model are DepthMovie, MomentumXMovie, MomentumYMovie, VelocityMovie, VelocityXMovie, VelocityYMovie.elocityMovie, VelocityXMovie, VelocityYMovie. +

A python code for modeling the dense endme … A python code for modeling the dense endmember of pyroclastic density currents (PDCs) generated either by impulsive column collapse or sustained fountaining eruptions. Dense, particle rich PDC is modeled as solid-fluid mixture driven by gravity analogous to the granular flow models of Iverson and Denlinger (2001). Flow movement over real topography is realized by using a digital elevation model (DEM) file as one of the model inputs. Other model inputs include simulation time, flow density and viscosity, x and y coordinates (or longitude and latitude) of the source, among others, which are input to the model either using a config file or via command line arguments.config file or via command line arguments. +
