WebTherefore, the capillary rise within a soil can be written as: (6.8) ( ) 0.15 ( ) D10mm hcm≈ As you would expect, finer the soil, smaller the capillary tube diameter, and larger the capillary rise. This can be also inferred from Eq. 6.8, which works well for sands and silts. Gravels are so coarse that there will be negligible capillary effects.
