Table 3 Parameters for the sensitivity analysis of FlowDIR applied to the three case studies. When not being tested, parameters were set to the values used in the case studies (Table 2). Note that due to differences in the DEM resolutions between volcanoes the start uncertainty measured in metres equates to a different number of DEM cells for the case studies
Input variable | Values tested |
|---|---|
Buffer | 20, 50, 100, 150, 200 m |
Start uncertainty | 10, 20, 30, 40, 50 m |
DEM resolution | 5, 10, 20, 30 m |
