See section on methodology for details of procedure s(2 ) The percentage of gravels by weight may be converted to an approximate percentage by volume by assuming a density of 2 .6 g/cc for the gravels and a bulk density of 1 .3 forthe less than 2 mm fraction .(3) The values for estimated available water (storage capacity) for plant growth are based on the differences between field capacity and wilting point . The total amount o favailable water may be estimated by multiplying the estimated available water in cm/cm 2 by the rooting depth . In Yoho, unless there is a lithic contact, the rooting depthis frequently in the order of 100 an, but can vary from site to site .(4) Permeability classes of slow, slow-moderate, moderate, moderately rapid and rapid were used roughly as defined by Soil Survey Staff . 1951 .
