Hi all,

I was wondering if HEC-RAS uses values from the .uXX file to simulate the WSE at the downstream end when the option Rating Curve is selectionned rather than the limited curve of 50 points in the Unsteady Flow Data interface. I can see 150 points in the .uXX file but I’m unsure if HEC-RAS does extrapolate or not after the 50th value from the interface instead of using the values that goes beyond the 50th pint in the .uXX file.
