Hi,
As can be seen from the photos all input is same but the results are are different. I can't understand the reason of this. ı also upload my input file both HY-8 and Hec-Ras as an attachment. Thanks for interest...
I need to make calculations detaily in my work about culvert in both software. I try to show reasons of different result by determining different methods and calculations. Which steps are different in these programs(like friction loss equaiton etc.)
