Fig. 3: Spatial Accuracy of Modelled vs. Observed Debris Flows.

From: Predicting debris flow pathways using volume-based thresholds for effective risk assessment

Fig. 3

The accuracy of simulated debris flow to the real-world condition. a The percentage of area of true positive, SH-type is well matched with real world scenario. b The percentage of area of over prediction. High over prediction in SC-type debris flow and low in SH-type can be seen. c Under predicted area is very less for both SC-type and SH-type of debris flow. d Kavalappara debris flow in Malappuram district, Kerala overlaid with real debris flow area and area simulated (Image source (d): Google Earth; Software used (a–c): R and (d): RAMMS::Debris Flow).
