      abstract     = {A Cone Penetration Test (CPT) survey with a high spatial
                      resolution was performed in order to investigate the
                      stratigraphy as well as the spatial variability of various
                      soil properties of the Krauthausen test site. Analyses of
                      the CPT measurements showed the subsurface to be dominated
                      by a planar layered structure. Variogram analysis of the
                      various CPT parameters disclosed that within each layer the
                      soil properties have an anisotropic spatial correlation
                      structure. A correlation analysis of the measured CPT data
                      and co-located grain size distributions from soil samples
                      was performed. Since the correlation coefficients were
                      greater equal to 0.7, a reliable empirical relationship
                      between the data sets could be developed. Based on this
                      empirical relationship grain size distributions were
                      estimated at CPT locations. The statistical processing of
                      estimated and measured grain size distributions with respect
                      to their spatial correlation structure disclosed good
                      agreement between the data sets. The estimated grain size
                      distributions from CPT data were used to estimate the
                      hydraulic conductivity in the aquifer. The results provide
                      detailed information of the spatial heterogeneity of the
                      hydraulic conductivity at Krauthausen test site. The
                      validation of these results, using a prior investigation of
                      hydraulic conductivity statistics, suggests the CPT a fast
                      and inexpensive tool for the estimation of three dimensional
                      hydraulic conductivity fields with sufficient accuracy.},
