HEC-RAS T2: How To Calculate 100-Year Flood Flow and Water Level

[@sourabhsuresh6578]

Hi Sir, your videos are very helpful, but the data are not available in the link you provided can you please share it again for all your videos.

[@traveltoeurope007]

sir, Can you please kindly give the data again because it's saying the data is deleted from the drop box link? thank you for your service. It's really helping me a lot.

[@akhtarzebkhan1989]

Thanks you so much for your sharing. I didn't have the discharge (flow rate) &water level data at the exact location of the river. How to calculate return period in my case. It's a humble request to guide me.

[@MdArifurRahmahn]

Glad it helped. You can follow the method I demonstrated.

very useful video, but data link above does not work. Could you please provide another link for data?

that's very clair thank's

You're welcome

Great tutorial, I noted one thing on Excel on computing wl with return period, you used Log instead of LN. The value WL is somehow lower, please correct me if I'm wrong

[@MdArifurRahmahn]

Thank you for the query. Yeah, I used log instead of LN. I usually use log so that I can specify the base. For log10, there is an specific function called log10. Previously Ln was not there in excel. That's why, we used log and used the based. Now I can see there is LN option. But still I use log as a habit, even though I don't use excel for the calculation. Here, you are absolutely right that the value is lower as I forgot to use the base. You guys can use LN.

great video, how to calculate 25,50, and 100 year return period flood flow at hourly or daily level? for unsteady flow, I need a flood hydrograph at a different return period. thanks in advance

[@MdArifurRahmahn]

Thank you for the query. Use the hourly maximum or daily maximum first; then, calculate the flows of the respective years return period following the steps.

[@buddhirajshrestha1640]

@@MdArifurRahmahn thank you so much for your response, you mean I should follow the same steps as your video for hourly and daily

Dear Sir survey dada is not there now. can you please add it again.

[@aarizahmed2422]

Very Informative Video tutorial. Can we do the same exercise for the lined canal? Could you please make videos with canal?

[@MdArifurRahmahn]

Yes, sure. I will make it. modeling with lined canal is more simple.

Sir, how to give reference for this video for my research purposes. Or can I get any research paper with this methods in it.

[@MdArifurRahmahn]

You can find the document of Generalized Extreme Value (GEV) Distribution method.

hello thank you for the video. i have a question i tried extracting my gis data from hec ras but they were saved as sdf file format. how can insert my sdf file to arcmap since i need a flood/inundation map?

[@MdArifurRahmahn]

You need to convert it as either shapefile, or raster.

why are the files in the link deleted :(

[@keyable]

Could u pls reupload the data? thnx!

[@Begoodbhg]

can you do python methode to find level from flow?

[@vaibhavgawade1129]

what is the name of river ?

[@MdArifurRahmahn]

It is called Muhuri Rver.
