Study on the spatial variability of hydraulic conductivity

The spatial variability of hydraulic properties is the basis of stochastic research on groundwater.The hydraulic conductivity is the most important parameter.There is still no exact answer to the question about the distribution of hydraulic conductivity though studies dealing with this topic are numerous.In this paper,a discussion of Sudicky's (1986) field experiment for the geostatistical characterization of the hydraulic conductivity at the Borden aquifer in Ontario,Canada is performed by using the different schemes of the data disposal.The results of the analysis suggest that the distribution of hydraulic conductivity is lognormal by using the appropriate method.In addition,some useful advices are provided for carrying out the field study on the spatial variability of hydraulic conductivity in the future.
