Flood Inundation Mapping Using Remote Sensing DEMs and HEC-RAS (for data-limited areas)- Part3

[@takeleabebe255]

your video is very real and informative than other HEC RAS video which is based on fake data by assumption. i regret wasting my time with those fake video. i have question regarding the discharge valued you entered in steady flow data that is 150, 400, and 1500. where do you get these number???

Hi Takele, Thank you so much for your feedback. Have a good time.

EXCELENTE DEMOSTRACION INGENIERO, MUCHAS GRACIAS

Thanks ever so much

You can say that, regarding geometric data, we have actual measured vertical and horizontal cross-sectional data; Is it possible to merge these metrics into Ras-mapper?

[@HydroAI2024]

Yes, Of course. You can create a DEM using observed CS data and then combine it with RS DEM or other DEMs and create a new DEM. Best

Can u please tell that return period table can be made for unsteady flow as well ?

[@HydroAI2024]

Yes, this table can be used for unsteady flow. But, remember that you should have a flow hydrograph for unsteady flow simulation. You can use the Triangle hydrograph and the specific return periods. For example, create a triangle flow hydrograph based on Q25 or Q100 and then run the insteady model.

can u suggest any video for it ? Or u can make a video on it on ur channel

[@HydroAI2024]

@@hadiqaqadir2603 IF you search on the internet about triangle hydrograph you can more about this method.
