... The FLOWGO thermorheological model of Harris & Rowland (2001) allows a one-dimensional (1D) simulation of downflow changes in rheology and velocity of basaltic lava flowing in an already established channel. FLOWGO applies a cooling model, based on the first principles of radiative...

... for Etna, indicating that the MAGFLOW default values are not perfect for the two Chaîne des Puys cases, but do allow a reasonable first approximation. For FLOWGO, the difference is greater (Fig. 4 ). Using the default values, the run-out is shorter and the velocities lower. The difference in run-out...

...-dimensional model for the downflow thermo-rheological evolution of a channel-contained lava volume, FLOWGO ( Harris et al. 2015 ), we move to the use of depth-average equations for lava flow modelling ( Costa & Macedonio 2005 ), as applied by VOLCFLOW ( Kelfoun & Vargas 2015 ). We then turn...

.... Ishihara et al. (1990) and Miyamoto & Sasaki (1998) use fluid dynamics and cooling equations to calculate the lava spreading in 2D (runout and width) on an incline. FLOWGO ( Harris & Rowland 2001 ) estimates the lava trajectory based on similar dynamics and cooling equations on a realistic...

... and yield strength are given as functions of both temperature and crystallinity, as in FLOWGO ( Harris & Rowland 2001 ). In this paper, we introduce the LavaSIM code ( Hidaka et al. 2005 ), and provide some case studies showing the advantages of the three-dimensional (3D) thermal dynamics formulation...

... for lava flow in a confined channel (the FLOWGO code). In Hidaka et al. (2005) , a three-dimensional model for a Newtonian fluid, which includes energy conservation, solidification and free surface, was presented. A variant on the deterministic approach is the cellular automata method. This allows two...
