QDebrisFlow
Plugin ID: 5479
Modelling of post-fire debris flows (O'Brien quadratic rheology + LIA). Two tabs: single run and multiple-run (LHS) analysis with calibration against the observed inundation zone and depths. Individual source hydrographs, output layer selection.
This plugin has an experimental version available!
Models post-fire debris flows based on the quadratic rheological model of O'Brien and Julien (1985, 1988) and the local inertial approximation of the shallow water equations (LIA). Based on the FLO-2D formulation. Outputs: maximum depth envelope (h_max), maximum velocity (V_max), maximum of the instantaneous h·v² (HV2_max), Froude number at the peak h·v² (Fr_hv2), final deposit (h_final), flow arrival time map (t_arrival).
