Levees versus Effective Areas
Levees versus Effective Areas
(OP)
I'm working on a large watershed model in HEC-RAS and having a discussion about whether it is better to use effective area to show areas of no flow or to use use levees to show where the flow should go. My question is "If you use effective area aren't you discounting HGLs in the main channel if you allow it to spread through out the cross-section. Some of my cross-sections are very large and I'm thinking levees are better.

So you need to make the decision based on what will happen in reality during your modeled condition.
