Comparison of Saturated Hydraulic Conductivity Measurement Methods for a Glacial‐Till Soil Academic Article uri icon

abstract

  • To evaluate the performance of four in situ saturated hydraulic conductivity (Ks) measuring methods, Ks measurements were made at four depths and five locations on a glacial-till soil of Nicollet (Aquic Hapludoll)-Clarion (Typic Hapludoll) association in the Des Moines lobe, central Iowa. The Ks was also determined in a laboratory on undisturbed soil cores. The Guelph permeameter method gave the lowest Ks values, possibly because of small sample size, whereas the disk permeameter and double-tube methods gave maximum values for Ks with minimum variability, possibly because of large sample size. Estimates of Ks however, are most comparable for the velocity permeameter and the laboratory method using a constant-head permeameter. -from Authors
