Hello, Why is it necessary to make a breakline and re-enforce cells where we are going to place an internal boundary condition (hydrograph) ? I am assuming that is to send water perpendicularly to the BC Line (in other words, to send water parallel to the slope), but i am not sure ?
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!
@@ianhernandez3683 I followed the tutorial last summer and I don't remember very well. I imagine you just have to create a refinement region along the banks This afternoon i will check a small guide i did on spanish with screencapture following the tutorial. I can send it to you
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
As far as I know, negative values are not allowed - although this would be a very handy feature in being able to reset hydrographs in specific areas inside the 2D flow area. Some of the other 2D models I use allow negative inflows or negative rainfall to represent infiltration/storage. It's been on my wish-list for HEC-RAS for years. Maybe someone else out there has a hack?
One HEC-RAS video a day keeps unemployement away !

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 =)
Yup, I didn't know how he did that. I can't proceed in another step. Please notice me also if you know the steps

Hi, did you get an answer?

Hi Krey! How could you avoid the water travelling upstream? Thanks!
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?
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?
I cant change the boundary condition to internal, It keeps changing to external when I stop editing
Hello . Can I insert unifrom lateral flow hydrograph by Internal BC line on 2D?
Thank you.
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
Or break the 2d area where the BC lies (by subtracting a small region from the 2d area) and import the negative values to the External BC now.

how to make area in break line?
Can I have projection and DEM files
sir hi, just for advice, u explain it to fast, maybe if u can go slower that would be nice, thank you,
