suggestions to edit every XS at once?

[Anonymous]

Hi there,

I have a problem where my XS elevation data needs to be shifted.

Basically the d/s end will remain the same, the u/s end will be shifted up 0.4m. Everything in between will be a linear interpolation.

What is the easiest way I can achieve this without doing it manually? Potentially a HECRASController solution?

Or is there some way to covert a g##.hdf file to a .g## file to be used in HECRAS?

Any suggestion would be greatly appreciated.

Thanks

I managed to write a script to manipulate the .g## text files and alter the elevations, only problem is when I am writing it back out, HECRAS has a VERY particular format of the text representing the station/elevation data

looks like right justified tab/space delimited but weird because if there’s alot of decimals the text basically has no delimiter so I’m struggling trying to figure out the general theme of the text output

tried a few ways and can’t get it to write the proper way, XSs always end up looking screwy in HECRAS.

Anyone know how to format this text or any hints that could help?

UPDATE :

Well it was a fun experience 😀 but figured out that there was a tool in the Geometry Editor that does exactly this.

Geometry Editor -> Tools -> Vertical Datum Adjustment

Options to shift all XSs same value, or different values for each, also either just main channel or overbanks.

If anyone else ever needs this.
