The underained properties of soil can be estimated in the field with thumb, Torvane and PPT.

Is there a correlation between the Cu and C' values. Thank you.
 
No.

There are some correlations between index properties such as Atterburg limits and drained strength in some materials.

cu-c' correlation only by fantasy
 
The ratio c'/cu approaches unity as permeability increases.

For normally consolidated soils, phi-cu may be roughly approximated as 1/2 of phi'
