I have a problem with the velocity mapping in HEC GEO RAS.
After successfully completed Inundation mapping (Water surface generation and Floodplain delineation), I have started the Velocity mapping. Process of velocity mapping breaks at the point when “Computing XS Transition lines and Grids” is conducted.
I got the warning: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index.
In the dialog box “Velocity mapping” at that moment I get the message: “Failed to find velocity grid in float point format for profile P001…”
The procedure of velocity mapping is then stopped (when “Computing XS Transition lines and Grids” is conducted).
Can anyone of You give me the answer or a clue why this problem happens, and possible solution for the problem.
Thank You all for Your answers and suggestions!
