Application of Hydraulic Conductivity Scaling to Infiltration: Drainage Field Tests

摘要

Spatial variability of hydraulic properties is of theoretical and practical importance in soil physics. Theoretically, there is the question as to how the variability might be best incorporated into existing predictive equations. Practically, spatial variability requires a large number of field and laboratory observations to characterize a soil. Scaling of hydraulic properties of soils is developed, treating spatial variability vertically. The vertical scaling results in a scaled depth coordinate and a scaled moisture content. Once this vertical scaling has been accomplished, the scaled profile concept of Warrick, et al (1977) is used to combine profiles from different locations across the field. (ERA citation 05:014219)
