I'm getting this error like: "Requried /MustExist Filed:LongestFL_HMS is not found-LongestFlow Path1" in the creation of Prepare Data for Model Export (HMS). Anyway, the filed are added default(LongestFlowpath1 and CentroidalLongestFlowpath1). Can you please clarify?

Hello did you manage? Am getting the same error

[@JALAJDARPAN]

Keep spatial projection projection data frame same as Projected DEM,it will work

[@alvarorojas2021]

I have a problem with longest flowpaths, it does not generate a proper result. Does the Longest flow path generated by the Arc Hydro tool work, in the watershed processing tab?

Try to enable/disable background processing.

Welcome

[@landryfakage4014]

Thank you for this very informative tutorial. I need a help on how to fix an error I'm encountering while trying to run bassin model function. The error message is HRESULT E_FAIL has returned from a call to a COM component. Background processing from Geoprocessing option is disabled, and the project pathway directory isn't such long as that. Please, can you provide solution on how to solve this issue?

[@hakimhakim-qv7tx]

when i am computing the longest flow path, the operation is coming long time more than (30 min) and as not correct. what should i do?

[@ngaleegiba7511]

When using the option stream definition, You have to input the threshold value for the area. But for some reason, I cannot put any value. It always shows put a number lower than the largest basin area. And I am sure my DEM file has basins area up to 200 km square. How do I procced?

[@amuronimelda5818]

Thanks for the video. I was doing a project on my on and the data I was trying to add failed to be literally seen in the folder I had saved it on. I was wondering if you could be knowing the reason for that.

[@JustLearnCivil]

Which data? Did you use filter all files ( *.*) to search the data? If it is GIS data you are talking about then maybe the data is saved in default location which may be c drive in case you didn't change the save location.

[@amuronimelda5818]

@@JustLearnCivil It's a DEM with file extensions of .adf and .XML......the data was on a flash then but I couldn't see it, so I eventually put it in one of my pc drives..but it wasn't the "c" drive. Are you saying that if I change the location of the files to the c drive then I may see it?

[@JustLearnCivil]

Open ArcGIS. Click ob add data then navigate to the location where you have saved the DEM. You will see a raster DEM of the same filename. Cilck on it and add it. The DEM will appear under ARCGIS layer. However, when you navigate to the folder in windows explorer, you may not see it. But through ARCGIS, you will be able to add the file.

[@amuronimelda5818]

@@JustLearnCivil thanks so much

[@patrickperales1993]

Does not having an area for the stream segmentation affect the result? In my case, the threshold for the area is shaded with grey, and it does not allow me to input an area.

Hello, what is the difference between generating the preprocessing with ArcHydroTools and HECGeoHMS? I've seen several tutorials where preprocessing is done with the HECGeoHMS tool and I don't know if there really is anything different. Regards.

[@JustLearnCivil]

You can use any.

[@ganadeepansubramaniam2575]

Is it possible to do same thing if I have already have the shapefiles? I need to find the hechms processes (scs, modclark and recession) and average slope

Yes you can strart the process with your shapefile (From this shapefile obtain the pore point). Then follow the process mentioned in the video.

[@aakritideuja3333]

Hello! please help me. Where can i find the dem and basin boundary data for rapti or karnali basin?

[@JustLearnCivil]

Download DEM from USGS website. You will get data of whole world there. Download the grids of karnali basin by specifying latitude and longitude.

[@aakritideuja3333]

@@JustLearnCivil Thank you for your response. and what about the basin boundary?

[@JustLearnCivil]

First you must know outlet of basin which is a hydrological station of DHM and using the coordinate of this point delineate catchment from your downloaded DEM. Remember that you cannot download DEM of exaxtly Karnali or other basin. You will get rectangular sheet so you may need to download more than one sheet and merge it in GIS software. Once you delineat catchment, convert it into Polygo which represents boundary of your basin.

[@renziegando8579]

How did you create your terrain dem data? Can i use dtm instead of dem? Thanks

[@JustLearnCivil]

Download DEM from online resource of your study area and clip it according to your catchment and use it. I'm not sure about DTM.

[@moteherogame]

plz! HELP!!! When I came to the parameter section----Subbasin Parameters from Raster. My input interface does not have options to input the SCS-cngrid. And it only has three rows, not like yours which is 8 rows. What I am gonna do? I want to input the cngrid parameter in subbasins.

Use ArcGIS version 10.2, if you have other version and HEC GEO HMS for version 10.2.

@@moteherogameYou mentioned having only three rows in subbasin parameters from Raster. How many rows appears depend on what options you selected in "Select HMS Processes".
