Computation time of FlowDIR as a function of: the buffer width (solid black lines), DEM resolution (dotted red lines) and uncertainty (dashed blue lines). When not the parameter being tested, the values of the remaining parameters were set to those used in the case studies and detailed in Table 2. The original resolution of DEMs used are: Shinmoedake 5 m; Colima 30 m, Merapi 10 m
