SNOEB.sub (BAND)

[Rayen Rivera]

Dear SWAT-CUP users,

I am calibrating a watershead in Chile and the upper part has unsatisfractory values for my objective funcion (NS).

I made the Elevation Bands, and the calibrated PLAPS and TLAPS. After that I have calibrated the tipical 5 snow parameters, but now I am trying to calibrate SNOEB.sub (Initial snow water content in elevation band) as I guess that might help (I already tried calibrating SNO_SUB but nothing changed... then I realised this value is not used if the subbasin is divided into elevation bands).

After it runs, I go to Sinle_Obj_Post.bat and it gives me the error:

C:\SWATCUP-Premium\RAYEN\REG_COMPLET\REG_COMP.Spe.SwatCup>SPE_Single_Obj_new_pars.exe
!!!!    Singular matrix in routine LUDCMP    !!!!
C:\SWATCUP-Premium\RAYEN\REG_COMPLET\REG_COMP.Spe.SwatCup>SPE_Single_Obj_95ppu.exe
SPE_Single_Obj_95ppu     ......done

Question: Is there any other way to set the Initial snow water content (SNOEB) in the elevation bands??

Please find my input files and a screenshot of the upper subbasin that is giving me trouble (Flow_out_8 and upstream subbasins).

Thanks!!!
