This is the great presentation I was searching for. I searched for the tutorial which starts from the scratch. Now I get it here from your channel. Thanks Sir for sharing your knowledge. I appreciate

Thank you for the tutorial, sir. I followed the steps exactly as you demonstrated, but during computation, I keep encountering the error: 'Error executing: StoreAllMaps - RasMapFilename '' does not exist.' Could you please advise on how to resolve this issue?

Hello Sir. Thank you for the tutorials . They have been helpful so far. Please could you help me understand how to get the values for the 1D steady flow boundary conditions for upstream and downstream for a river. Normal depth and critical depth

Dear , your videos are very clear but I have a project on an irrigation channel that has main and three secondary canals please how can I model this I could not get any information in this regard. please share with me if you have any hints.

Its a gret tutorial for learner but data file is not available at the moment. it would be so helpful for learning if you provide the data file.

Hello sir, I have a question not that related to the video but may I ask how will you get each area of the river?

Sir, I choose 10 cross-section along a river. Now those 10 cross-section are not capable of handling the total flow capacity. I wants to alter the cross-section, so that it can carry total flow. Will this alteration only will be there on those cross section? Or it will be applied to entire river strech??

@MdArifurRahmahn 2 жыл бұрын

Hi, thanks for the query. Yes, you need to alter the cross sections for the entire reach of the river, especially the sections in between the u/s and d/s boundary. Otherwise it will violate the continuity equation, Q = AV, and the channel will not be able to carry water.

Thanks Sir for sharing the video, I learned a lot , but I have a question. I set locations for flow distribution and selected 1(LOB, Channel, ROB), I also saw the distribution of different flow velocities on a cross section. I don't know why the result of selecting 1 or 10 is the same.

@MdArifurRahmahn 3 жыл бұрын

Thank you for the query. Since you have set the flow distribution as global instead of local. That is why it's the same. If you change it to one, then you will have different plots.

Sir, how to choose Manning’s n or k values

@MdArifurRahmahn 2 жыл бұрын

Thank you for the query. The roughness factor depends on the channel bed-, and bank-material . You can find the values of n and k from hydraulic books or published document.
