Wet / dry cell in 2D flow area

[sam1]

hi,
after a simple 2d simulation in hec-ras, how can i get the information of the number if wet or dry cells in the flow area at differents time steps?

You would probably have to check the HDF files for this and write a script to automate it. I don’t think there is a way in Mapper to tell you this.

yes, thank you for your answer, actually this is what i did. But in the HDF file you have the depth in each cell, so cell is considered dry if depth equal 0 and wet if depth>0. But to calculate the flood area extent, is there any other method than considering wet cells? Because the water may not cover all the cell so to calculate the flow extent not all the cell area should be considerd.
