摘要：

An inverse relationship exists between the longitudinal electrical conductance (S) and the leakance (L) of sediments between a bedrock aquifer and a surface-water body. The empirical relationship for western Lake Michigan, first reported by K. R. Bradbury and R. W. Taylor (1984), has been refined after additional measurements. Leakance can now be predicted from longitudinal conductance with 95% confidence to within plus or minus one-half order to magnitude. Evidence is also presented that sediment samples collected by coring give erroneously low values for hydraulic conductivity and leakance.
