very very very helpful video thank u

@HydroAI2024 Dear Sir can you please tell how to get the UTM into .adf file to open it into terrains of HEC RAS please sir 🙏

Where did you get your ALOS-30m RAW file

You can download it from the below link: portal.opentopography.org/dataCatalog?group=global

Hi, Please follow the steps which are explained in the videos carefully. However, if you describe your problem I can better help you

i am facing problems in converting my extracted DEM to UTM coordinates. please help

Hi, If you explain more about your problem I can better help you

[@priyangshunag1972]

Thank you for reaching out very quickly. I just figured out the solution just now.

[@priyangshunag1972]

Actually i was unable to get the output for Decimel to UTM conversion but then i saw that i had not selected the output raster dataset of the selected file

Thanks this is help full. Please show dam break modeling from river cross section up to flood mapping. How to make small river cross section?

Sir how we calculate sediment yield in reservoir please make vedio on that ❤

[@HydroAI2024]

Hi, For sediment modeling in the reservoir, there must be done some techniques. However, if you take a look at this course you can find about reservoir modeling.

Teacher, Do you teach online?

[@HydroAI2024]

Hi, Yes of course. Using online platforms, I can teach you about flood modeling (1d or 2d).

​@HydroAI2024 hi! Notice me pleaseeeee... Can HEC-RAS be used in flood modelling without river? I mean I just want to model flood caused by fluvial flood (flood caused by drainage systems)
