FAQ/ Definition of Inundation Duration

Does the flood duration exported by DioVISTA comply with the following definitions in the Flood Area Mapping Manual (4th Edition)?

Manual for Mapping Flooded Areas (4th Edition) p. 30

If the water recedes and falls below 0.5 m, and then rises again to exceed 0.5 m, the total time (including the time when the water falls below 0.5 m) from the time it first exceeds 0.5 m to the final fall below 0.5 m is set (Figure 5.2).


Yes. You are right.

The flood duration output from DioVISTA is calculated according to the concept specified in the manual.
