Seasonal Water Yield_CN and Kc values

Hi, everyone !
I run the SWY model in a small watershed and changed the CN and Kc values, but there was no difference among those results. This might reflect the fact that the result is not very sensitive to CN and Kc values. But does anyone  know the specific reasons, and provide some relevant literatures for me? 
Also, could anyone know where I can find the CN and Kc values for semi-arid region?  
Thanks a lot!!!!

    Is it possible that the values you changed weren't covering landcover codes or soil types that were represented in your raster inputs? I'm sorry, I'm otherwise not familiar with the relevant literature.
