HEC-RAS Basics Part 4 of 8: Internal and external boundary condition setup

Nice videos. Does anybody know when drawing an internal BC line on 2D is the same of drawing it from right to left or vice versa?

Hi Krey! How could you avoid the water travelling upstream? Thanks!

Hello Krey, I would like to ask you if, when using precipitation as a boundary condition, it is necessary to introduce external conditions such as normal depth. Thank you very much. Great videos!

sir hi, just for advice, u explain it to fast, maybe if u can go slower that would be nice, thank you,

Hello . Can I insert unifrom lateral flow hydrograph by Internal BC line on 2D?
Thank you.

how to make area in break line?

I cant change the boundary condition to internal, It keeps changing to external when I stop editing

In this tutorial there is a refinement region along the banks. It was not created in the previous tutorial part 2 of 7. Just people to know =)

Hello sir, I really interesting and want to use this model. But I don't have any data to practice. could you please share me for example data?

Hello Krey. Very nice tutorials.
I am having errors when inserting negative values in flow hydrograph on Internal BC line.
Is there a limitation for this option?
Can negative values only be inserted on External BC lines?

Thank you
P. Marinis

Can I have projection and DEM files
