Very helpful video. Your English is very good!

very helpful video on scour

alhamdulillah, thank you brother for the video

My pleasure

Sir, thank you for sharing the tutorial videos of HEC-RAS. I got a warning saying that "some parameters for pier and abutment scour require flow distributions. The flow distribution option has been turned on for the two sections just upstream of this bridge, therefore not all the usual default data will be available". However, I did set the locations for flow distribution. How should I do to solve the warning problem?

Thanks for your query. I need to see the message, I usually demonstrate this in details in my training. For more info, please send message to [phone] on WhatsApp.

Sir, I have done all these steps successfully and got similar results. Sir, I want to do sediment transport modeling in this model as well. Can I do this? or do I have to do it separate medel.

[@MdArifurRahmahn]

It's possible with this model as well, only need to change the flow condition and add the sediment boundary condition.

@@MdArifurRahmahn Hello sir, please tell me how I can change the flow condition? I changed flow conditions from steady to quasi and unsteady in two separate simulations. But both showed errors. Please guide me how I can do. I am clueless. I have to show this demonstration to my prof that I have learned. I am eagerly waiting for your positive response, Sir. please

sir, is it possible to simulate the scour caused by jet near sluice gate in a flume?

[@MdArifurRahmahn]

Thank you Divya for the very important query. If you mean jet by waterflow as open channel, then it's possible. But usually, by water jet, we mean waterflow from nozzle. For that case it's not possible because then the flow condition won't remain as open channel. It will be regarded as pipe or pressurized flow then.

[@divyathokala6217]

@@MdArifurRahmahn sir, it is open channel only not pressurized. Thanks a lot for quick response. Expecting more videos from you 😊 specially scour near sluice gate and other related problems near hydraulic structures.

Please provide sediment sieve analysis sheet

Thanks for the query. I offer training on this software, where I demonstrate how to develop a model from scratch. For more details, send message to me on WhatsApp at [phone]
