Hi all..I’m a new to HEC RAS.. I have a question about 2D modelling..
I try to calculate the velocity on the specific cross section..
I have defined the cross section and input the discharge data, but the result give a very big velocity such as 50000 m/s.. I defined the cross section automatically based on DEM terrain file and the discharge ranging around 8 – 20 m3/s..
Do you guys have any clue how to fix this error? Thanks
