Great videos. Very educative. I have really learnt so much. Can you please do some videos of Civil 3D on open channel longitudinal profiles

When adding CN number to hec ras, can we do it to a single map layer with different soil type? or should we input separate maps of each soil type?

Many thanks, Andrea for the well-done and comprehensive video about the calculations of the CN. I have a question about the assignment of CN =79 to the built-up area. Would not it be set to higher values (90s) to be similar to the corresponding values of residential areas given in the TR55 tables?

When I ran the zonal statistics, an error occurred saying "Feature from subbasin has invalid geometry" Is there a way to fix it?

Nothing else in the message? Difficult to say. did you go step by step? I should see the file!

Yes I did follow the steps from the first video. It also said in the error that "please fix the geometry or change the invalid features filtering option for this input or globally in processing settinfs." Thanks, btw.

I tried fixing the geometry, and I was able to run the zonal statistics. However, the mean column is NULL. It has no value, unlike yours.

Yes there is. On QGIS you must go to Vector/Geometry Tools/Check Validity to find which basin (shapefile) has a error. It happens.

Hello Sir. In my attribute table, one of the DN number is 11. How can I find the soil type and CN number for this?
@umitatak1565

He has written WHEN DN = 9 THEN 'Snow-Ice' ELSE 'Cloud' END . So That means after 9 all of them Cloud.

Sir, if my catchment is between 2 land use cover map. How should I perform the clip raster by extent? Cause I can only select one of the land use tif as my input layer. Is there any way to merged both landuse tiles together?
@AndreaCippa-Siteplanning

If I understood you right, you should merge the two rasters (with the land use information) together and then perform the workflow on the newly developed raster layer. To merge two raster in qGis have a look at this opensourceoptions.com/blog/merge-multiple-rasters-in-qgis-create-a-raster-mosaic

Sir i have a question. How can we calculated initial and constant or deficit and constant? Because i can't find any soil textures information about my location

Very difficult, you should probably survey your whole basin and make laboratory test of each subbassin. In refugee's settings, this would be almost impossible. In academic context it could be possible. I've simply neglected this factor. Hopefully someone can give me a better solution one day. Sorry for the unsatisfactory replay.
