thank you so much. I was wondering how to design a lake bathemetry terrain within Hec-Ras. You made it so simple and smart. Create a detention basin just like creating a river, very inspiring.
These is a great video, and an amazing channel. I am one of your channel's subscribers, and have found your videos really useful. So thanks for your efforts as well.
thanks a lot Krey. I have 2 ideas please for further contents, if you like: (1) since I ended my PhD I have wondered if is has been modeled in HecRas how climate change alters, along some years/decades, flood frequency via conveyance change due to channel morphodynamics. (2) intake sedimentation and ways to consider trash in the racks.
Hello Krey, Thanks for your helpful videos. Would you mind going over 1d-2d coupling particularly ‘connections’; also if you don’t mind using applicable time step in relation to cell sizes, distance between XS & channel depth. If you also talk about calibration. Thanks again.
Hello, i want to ask, i have already do a terrain mod of levee on the right and left side of my river, bud the water goes through the tributary river even if i already put levee over the right side, it goes through like a bridge, is it possible? how can i make it not go through? Thanks, i really need help
Good morning please i need help when i add a roadway then i make run unsteady i don't understand the erreur about boundery conditions and they said that HTab parameter for starting elevation is lower than the lowest elevation in the cross section main channel
In the geometry editor click on the HTab Param button in the lower left, select the cross section that's giving you trouble, and adjust the starting elevation to be above the low point in the cross section. Alternatively, you can just highlight the whole range and press "reset defaults". If you're still having trouble with it, contact me on www.surfacewater.biz/contact/.
Hello Users, I just need some insights on Breaklines.I have added breaklines into the 2d mesh area and enforced them as internal connections and entered weir data as top spillway elevation at 700m to the connections assuming they are acting as Embankments/weirs to the reservoir.But After I ran the Unsteady flow model successfully, in the results section in the RAS Mapper Water still flowing over the embankments at 653.55 only without filling the reservoir up to 700m elevation.What Should I do?Here I am attaching the supporting screenshots..Thank you in Advance#HECRAS #2dMODELING

Everytime i am stuck with a problem, its always you Cray who shows me the way. online for free. several years in advance. you Cray are a wizard!
Just stumbled on this and its got to be one of the most amazingly comprehensive tutorial videos ever. Bro you are a machine!!!
Thanks, Cray with this wonderful educational video. For sure it is one of the best episodes I have ever seen about Hec-Ras modeling.
These is a great video, and an amazing channel.

One of most useful channels on HEC RAS. Thanks
Wonderful!! these technics will probably solve much of my Master thesis work , Thanks alot
Holy cow! This is excellent!

Brilliant, thank you very much for these interesting tutorials
Thanks Krey, your vids are a great help & fun to watch 😉
Thanks, Krey! Great job!
"Costco's first skyscraper" was said so casually I had to do a double take haha
you are the best bro, thank you!!
Great tutorial! Really helpful.

how do i ideally download terrain modals please guide me sir i have failed
thank you dear so much
Hello sir, I added leeves but when I run the unsteady analysis the error comes about boundary condition what to do?
from where should i download terrain Data ?
