Thank you for this new demonstration of HEC RAC. What you are showing is very educational. Also you are going to incorporate a bridge in this tutorial and that gives a lot of weight to this video. We hope that the next videos will be even more demonstrative. Thank you very much because we are learning a lot from the videos you are showing. Merci beaucoup et bonne continuation . 😊
During your presentations you keep on referring to handouts, could you please share the link to download them so that after watching these presentations I can have somewhere to reference back to
Hello, thank you for the content. By the way in my project, I don't see the cross section option, nor the other ones below it, only the river and its bank lines and flow paths. What do you think is wrong?
there is a problem with your cross sections. You create them using the DEM data which gives the water surface height in between the banks. That is why it shall be modified according to the bathimetry data. Else you will be running your simulation on top of an elevated river with flat bed.
Hi! I've just finished doing the cross section. However, when I tried to open the "view/edit geometry data" in hecras, it said "Error Geometry Data". Is there something wrong with my geometry? And how could I know if there's a problem with my geometry? Thanks!
Thank you very much for the video, I have a question, how can we correct the geometry errors? I know that you right click and change geometry and they appear red, how to correct them?, thanks!
@@hydrologyvideos8253 Thanks for your kind answer, I've always had this question, is it possible to change the sensitivity value (the dotted circle that appears when the lines are drawn), it comes out too big, is it possible to place it smaller?
thank you, my thesis is due in a month and your videos really helped.
You really giving very rich contribution to the research community, and it must be appreciated

Thank you. Your presentation is clear and the information helpful in understanding how the models are developed.
Estoy viendo tus videos, me gusta la manera en la que explicas el proceso. Gracias.
Muy Bien!
Good tutorials, many thanks looking forwards for the next ones

the video description has a link to the handout.

not sure! Make sure you are using a relatively current version of HEC-RAS.
there is a problem with your cross sections. You create them using the DEM data which gives the water surface height in between the banks. That is why it shall be modified according to the bathimetry data. Else you will be running your simulation on top of an elevated river with flat bed.
good point! the DEM that is used here has bathymetry integrated into it.
👍

Prof., do we need to validate the river cross sections using field surveys? thanks
Ideally you want to use field data to create the DEM used for your study. The data used in this video incudes field cross-sections.

You should be able move vertices to change the geometry. I think you can also undo your digitization if you make a mistake while creating geometry.

@@soniacarolinalobocabeza4271 it is just a snapping tolerance. it appears big when you zoom in and vice versa.I would not worry about it.
How its computing everything without any discharge
