Hi Everyone,

I need to model Arch bridge of 5m lenght in Flood modeller. We can specify width and height in section data tab. Is there any option of selecting/adding length in the Bridge? 

Can i model the bridge as dual bridge to model the length?

Thank in advance for your suggestions.

I would advise not to model as a duel bridge as you will likely be overestimating the afflux. In order to retain the correct channel length (i.e. to account for the bridge length) you can either increase the distance to next of the upstream or downstream cross section by 5m or equally split it between them both.
