wow!!! great knowledge being shared
Thanks for your feedback
Impressive Work.
Thanks for your feedback
Excellent job
Thank you so much
Very Informative video, Nice work Sir 🤓
Thanks for your feedback
Hello, when I create the geometry of my watercourse, the boxes river, cross section, 2D flow, structures etc. are not displayed but rather "17 empty layers"
Hi Nanan, As I mentioned on LinkedIn, You need to watch my courses carefully and then you can easily simulate flood 1d and 2d for your case.
How to derive roughness coefficient values?
Hi, just search on the net bout roughness coefficient values for different land covers and then you will find practical tables for this issue.
@@HydroAI2024 where I would find tables any link or website?

How we can calculate discharge value of a river with different return periods for the research purposes?
Hi, Please watch the below course for Flood frequency analysis:

Hello sir i am not able to change the river station and elevation dimensions from metres to feet. Please help
Hi, Did you creat your model in SI unit or feet?
I was trying to reproduce what was taught in my region and two messages appeared. "Time series data starts after the simulation starts. Stage(s) in time series data are below the cross section minimum." What would that be.
Hi, the first error indicates that you run your model more than your input time span. try to use the same time span for both Time series data and simulation start and end time. the second one, says that initial water stage is lower then bed elevation and you should modify the stage level for better running
Good
Thanks for your feedback
Sir, if the river is connected with two river branches. how this modelling part changes.
Hi, First, you should create (digit) the mainstream centreline and then create the other branches. Before finishing the digitizing process, double-click on the main stream, and the model will automatically create a junction at the confluence location.
I hope this works
Best
@@HydroAI2024 Thank u sir, I have a problem with the inundated area. why is it not appear in the whole inundated area? it was congested to the cross sectional length only. how to avoid this problem.
Hi, May i see you outputs? and then I can help you. I mean inundated area..
I placed a junction on 2 rivers but it now views them as 2 different rivers not. 1
Hi, It's true. Despite splitting the river, now you have one river but 2 reaches.
@@HydroAI2024 it shows 2 different catchments
@@tanatswamagidi9626 Dear Tana you are talking about rivers, not catchments. First of all, start digiting the main river and then digit the tributary river and double click on the junction location and then the model will automatically split the main river into two different parts. Just this
@@HydroAI2024 okay thank you
how do i generate a terrain modal in hec ras sir
Dear Naleeb
If you watch to this video and other parts you can find the answer of your question. I've completely described how to download DEM and create geometry model in RAS Mapper.
