Could you tell me where i’m wrong?

Thanks in advance 🙂

HI @deschoni ,

Thanks for posting. It looks like something is wonky in the Biophysical table. Could you attach that table so we can see what might be going on in there?

In the future it also might be easier to attach the logfile instead of pasting the contents. Thanks!

Doug

Hi @dcdenu4 ,

I’m pretty sure that my biophysical table isn’t correct, but I have tried for the test. Here it is:  
[biophysical table\_KRZ.csv](https://community.naturalcapitalalliance.org/uploads/short-url/8UCKjNp0MtVoCy0kzHCaXxbySwk.csv) (100 Bytes)  
In column “lucode” I have written VALUE records from my raster, which I converted from Corine Land Cover data.

Regards,  
Desislava

Hi @deschoni ,

Thanks for uploading that table. It looks like the columns are empty:

```auto
lucode;CN_A;CN_B;CN_C;CN_D
1;;;;
2;;;;
3;;;;

```

If you don’t know what those values should be at the moment you could try just filling them in for now to get the model running. Here’s the Users Guide data needs section for the mode: [https://storage.googleapis.com/releases.naturalcapitalproject.org/invest-userguide/latest/urban\_flood\_mitigation.html#data-needs](https://storage.googleapis.com/releases.naturalcapitalproject.org/invest-userguide/latest/urban_flood_mitigation.html#data-needs)

> - Curve number (CN) values for each LULC type and each hydrologic soil group. Column names should be: **CN\_A** , **CN\_B** , **CN\_C** , **CN\_D** , which the letter suffix corresponding to the hydrologic soil group

and for the soil group raster:

> - **Soils Hydrological Group Raster** (required). Raster of categorical hydrological groups. Pixel values must be limited to 1, 2, 3, or 4, which correspond to soil hydrologic group A, B, C, or D, respectively (used to derive the CN number)

I hope this helps!

Doug

Hi @dcdenu4 ,  
Sorry for this later response.

I’ve run the model today again after I repaired the biophysical table.  
Now I have a new problem, which I can’t understand:

 ![error](https://canada1.discourse-cdn.com/flex031/uploads/naturalcapitalproject/original/2X/2/2830a97baea30d02babbecde49b3458edf57ae8f.png)

All the best,  
Desislava.

Hi again @dcdenu4 ,

My bad, sorry for that. It turned out that this error was due to the antivirus program on my computer.  
So the model ended successfully.

Thanks a lot!

Desislava.
