Good day .
I am trying to design a flood plain by autocad civil 3D and Hecras . The water surface which I have inport from Hecras into civil 3D is under my ground level in somewhere. Here is a attached photo of the profile .
I will really appreciate if anyone could give me advise on it.
Regards
Iman
Hi Todd
First of all , i want to thanks for your answer.
Isn`t there anything wrong ? I mean in my modeling.
Does it usually happen with water surface?

I don't think the WS is modeled correctly.
Any chance you can post just the data you built the WS from? Water surface on each section with elevation.
