Hec-Ras: Bridge perpendicular to cross sections
Hec-Ras: Bridge perpendicular to cross sections
(OP)
Hi,
I'm having trouble modelling a bridge in hec-ras (check out attached file), it is perpendicular to the cross section layout. The problem is that hec-ras doesn't like a bridge/deck that is not connected to the cross sections. The bridge in reality is suspended by piers. The problem with modelling piers is that the width is centred around the centreline thereby making the top stick out further than reality. Anyone had similar problems?
Cheers
Scott

RE: Hec-Ras: Bridge perpendicular to cross sections
From the figure you've provided it would appear as the bridge is acting more like a lateral structure than a bridge. If this is the case then, you may want to explore the lateral structure option.
What is this bridge spanning? Is there another reach you need to consider? You may need to provide more detail for the forum to comment further.
