Hi all. I trying to import Geometric data of a River to Hec-Ras with Geo-HecRas in Arcgis.
River Profile create and import from Hec-Georas is like to stair and seem to be not correct(Pic Num.1.). but Civil 3d show better and smooth Profile for River (Pic Num.2.).
What is the problem with Hec-GeoRas?
The river profile is the same in both pictures. Only the horizontal scale of the second picture (Civil 3D) is different and the axis is displayed longer. If you generate the same scale profiles, it will overlap each other !!!
In other words, you can also find the difference by reading the axis values which is not readable in the Civil 3D generated figure.
M. Assem Mayar thank you for your answer but the river profile in both has same scale(1h:10v). the file attached in this reply show civil 3d profile with better quality.
Furthermore, if it was a display issue, river profile from civil 3d and arcgis should not have been different in hec-ras.
Amin Ebadi far you didn't get the point correctly, the scale might be the same, but is the size of both graphs horizontally the same? No!
In simple words, you can extend the length of the HEC-RAS profile figure, then you will see! Additionally, the values are the same, so there is no difference and the visualization is not a problem.
M. Assem Mayar The Problem is this: river profile from civil 3d and arcgis is different in Hec-ras and Civil 3d export better profile to it.
I think civil 3d interpolates and creates smoother profile and cross sections than hec-georas...
