Yes, I really don’t understand the problem. Using the datum adjustment manually takes a long time, because I’ve many cross sections and many points for each cross section, and the adjustment is different for each point, it’s not homogeneous…

Actually, the cross sections are correct, the only issue is the value of the elevations. They are like if we’ve introduced a scale factor

Thanks for your response Sir.

The elevations are correct before exporting, I even checked the cross sections profiles before exporting them, they are correct. Also, the cross sections have been digitized correctly, from left to right in the direction of the flow. So, what’s the problem then ?

Thank you Sir. Actually, I’ve already seen the diagram in the user manual but I think that I didn’t understand. So, according to what I’ve understood, the deck width is W as shown in the following figure :

The BU and DU are the cross sections just upstream and downstream of the bridge that are definied automatically by the HEC RAS, is it right ? So the width is the distance between these two typical cross sections. Am I right please ? If not, could you help me please ?

Thanks

Thanks a lot for your explanation, I get it.

Have a nice day Sir,

Thank you very much Sir, I’ve read the user’s manual help many times but I still have problems with bridges, I think that I must persever more, it requires experience… Thanks a lot and have a great day too

Amel.

Thanks a lot Mr. Robert, true enough, I prefer levees too because it’s simple.
