When modeling piers does HEC RAS assumes that piers are continuous or single? For example when i turn on 3D CS plot on my model i can see that all piers are single (2 rows each of 3 piers on the US and DS section), but really i need to model 3 continuous piers that have same length as bridge deck width. How to do that? I noticed that that kind of choice can only be done when u have class A flow and use WSPRO equations in bridge model approach.
Thank you for your time
