This video
demonstrates the multiple realizations for the statistical parameters of the
Borden aquifer, Canada ( Sudicky ,
1986). Details are provided in Tables 2.1.1. 

The following
observations can be made from the video:


Any aquifer can be
statistically represented using a mean, ln K variance and a
correlation scale. A brief description of these parameters is given below:
The Borden aquifer is
a test site, which generated a large amount of hydraulic conductivity data
with extremely fine resolution. Using this data, Sudicky
(1986) performed a statistical analysis to obtain the mean, variance and
correlation scale for this site. Given these parameters, it is possible to
create a random field that statistically represents the Borden aquifer.
