520 $a Hydrologic modeling of near-surface soils requires characterization of the vadose or unsaturated zone. This study describes methods to measure saturated hydraulic conductivity in the field and laboratory for characterizing shallow ( $< $1 .0 m) unsaturated zones. The field work was mainly directed toward characterizing the upper 50 cm of soil in order to better model performance of vegetative field covers. The cover vegetation will eventually be applied to hazardous, radioactive, and mixed-waste landfills at the Savannah River Site. As such, the careful consideration of water infiltration and runoff are critical to water-balance modeling.
520 $a Field and laboratory testing techniques are discussed, namely falling-head and constant-head laboratory tests, and double-ring infiltrometer and Guelph permeameter field tests. Over 50 tests of each type were performed in the laboratory and field and their results are compared. Geostatistical methods are applied to lend greater insight into the spatial variability of the results.
520 $a Based on the tests performed here, falling head laboratory tests yielded the most consistent results while the Guelph permeameter showed a great deal of promise as a field method. The standard descriptive statistical methods yielded little insight into the distribution of saturated hydraulic conductivity. However, some trends in the soil properties became apparent using spatial description methods, and describing spatial continuity using covariance functions. A baseline study applying ordinary kriging method for estimation purposes was established.
