Blue Kenue 3.12.2-alpha has a menu item that can extract the maximum flood extent during the simulation.

To extract temporal maximum of water depth:
  • Tools > Extract Surface > Temporal Maximums

If that's not what you are looking for, please try explaining in more detail so we can help you...

Kindly,
Alan

Thanks for your help.Actually Maxmimum water depth is not what I want.
For example,we consider a point is submerged when the water depth is larger than 5cm.And I want to know the duration that the water depth is larger than 5cm in this point.It means I want a time. I know it can exact the time series in a point. But i want to know the inundation duration in all the domain, it is unrealistic to extract all points.

PostTelemac on QGis can achieve this.
In ExtractMax tool, you can compute arrival time and flood duration.

  1. Tools > Calculator - Use the calculator to threshold your data (create 0 and 1 values), frame by frame, and create a new file in the process
  2. Load the new (thresholded) file into the work space
  3. Tools > Extract Surface > Temporal Sums
