Inundation statistics

Inundation statistics can be calculated and stored as a dfs2 file. Seven quan­tities are calculated and stored as separate items in the output file:

1.       maximum water depth, Hmax (j,k)

2.       time at maximum water depth, T@Hmax (j,k)

3.       maximum flux magnitude, Fmax (j,k)

4.       time at maximum flux magnitude, T@Fmax (j,k)

5.       maximum current speed, Vmax (j,k)

6.       current direction at maximum current speed, Dir@Vmax (i,j)

7.       time at maximum current speed, T@Vmax (j,k)

8.       duration above threshold (Optional)

These are all initialized as delete values and subsequently updated according to the specified update frequency (wet points only).

Water depths are grid cell centred values. All items in the inundation statistics are evaluated at the cell centre, making them directly identifiable with the val­ues from the HD output files.

Please note that the 8 characters “Aaa.dfs2”, are added to the user specified file name automatically. Here “Aaa” is an area number identification where the uppercase “A” is fixed and “aa” is replaced by the respective area number (e.g. “A01” for the main area, area number 1, and “A02” for area number 2, etc).
