Support Request about Calibration of slope

[Barbara Popczyk]

Dear group,

I am working on manual calibration of WRF-Hydro and stucked unable to gain any changes in model performance. 

 I run it with activate OVRTSWCRT = 1, CHANRTSWCRT = 1, channel_option = 2 (Musk.-Cunge-reach), FORC_TYP = 5 (with my precipitation data). 

I already tried to modify refkdt (and it is the only parameter which gave me noticable changes), LKSATFAC , OVROUGHRTFAC, RETDEPRTFAC in Fulldom_hires.nc, OV_ROUGH2D in hydro2dtbl.nc and slope in GENPARM.TBL. Othe listed variables do not give me any significant changes. 

I would be very grateful for any suggestions, what can I do to obtain better results.

 Maybe I modify the parameters in wrong files? 

Where should I modify the value of slope? I found it only in GENPARM.TBL and soil_properties.nc (slope=0.1).

Best regards,

Barbara

Hi Barbara, 

Some of the parameters that were in the GENPARM.TBL file have been moved to spatial files such as the soil_properties.nc file. Therefore, the model will read the parameters from the spatial files such as soil_properties.nc file, and not the GENPARM.TBL file. Slope in particular is in the soil_properties.nc file, please make modifications there. 

Thanks!

Arezoo
