Variations of hydrological parameters of tuff and soil
- Lawrence Berkeley Lab., CA (United States). Earth Sciences Div.
In this paper the saturated and unsaturated flow parameters of Yucca Mountain and Apache Leap tuffs and Las Cruces sol are compared. The saturated permeability generally has large variance, spanning over 2 to 4 orders of magnitude within each medium. Among different media, the mean value of saturated permeability are approximately proportional to the square of capillary radius. The capillary radius is determined by the unsaturated characteristic curve. A simple relationship between the variance of saturated permeability and the variance of pore-size distribution index is deduced from these data sets. These relationships could impose constraints on the choice and scaling of hydrological parameters for fractures, faults, or other units with scanty measurements.
