Hi,
what is the best position for Upstream/ down stream bridge face cross section?
As i went through the Ras examples, I found that different distances used for these cross sections!
Is there any general rule to find these distance?
Cheers.
The suggested “rule of thumb” by HEC and many others is to locate the bridge bounding cross sections as close to the bridge as possible without being on the bridge or approach embankments. In otherwords, put it as close to the toe of the embankment as possible.
