[Houssem Hmaidi]

Hi everyone,

I am working on a 2D project with Hec ras and i am trying to configurate/understand recession/duration/arrival time maps in Ras Mapper and how can i use them.

If anyone has an idea about this matter or where can i find informations please let me know,because i checked the manual and i could not find a fulfilling answer.

I really apprecaiate your help and suggestions.

The arrival time is at what time the cell gets to a depth you specify.
The duration is how long it is at a depth you specify.
The recession is how long until it drops below a certain depth you specify.
