“…In practice only a limited number of functions need be considered to satisfactorily describe most kinds of geohydrologica l and geotechnical data, and of these the spherical and exponential models are the most common (Rosenbaum, 1987). These mathematical functions (`model variograms') can be used as a basis for kriging.…”

The aquifer which forms the main water supply for the municipalities of MalmoÈ and Lund owes its value to the deposition of coarse sands during the deglaciation of the late Weichselian ice. Spatial statistical analysis based on construction of the variogram has been applied to the hydrauli c conductivity of this aquifer. This has identiWed an anisotropic distribution of the geohydrologica l properties with the least continuity striking in a north-northwes t direction, consistent with the believed Xow direction of the Weichselian melt-water streams which deposited the coarse sands. The application of geostatistical estimation (kriging) to model the distribution of hydraulic conductivity within the aquifer has honoured the depositional controls, notably the increased hydraulic conductivity towards the ice-proximal parts of the deposit.

“…In practice only a small selection of such functions are needed to satisfactorily describe most kinds of geotechnical data, of which the spherical and exponential models have been found to be the most applicable (Rosenbaum 1987 can then be used as the basis for a stochastic model which is capable of describing the spatial distribution. The model is applied by fitting it to the known data using the weighting coefficients which are dependent upon the distance from the observation points to the location of the site whose value is to be estimated.…”

Statistical analysis based on the spatial analysis of variance has been applied to the characterisation of Late Quaternary sediments within the valley of Kvilledalen in Gfteborg, illustrated in this paper by the bed thickness of the marine clay. The analysis of the thickness demonstrates a low random disturbance which was attributable to small scale environmental variability rather than to errors of measurement, and a maximum range of influence of 300 metres from the location of each observation point. Beyond this distance there was no spatial dependency and reliable prediction of values was not possible using the existing data. Stochastic modelling solved using kriging has been used to estimate the distribution of each bed thereby giving a quantifiable degree of certainty and improving the basis for predicting ground conditions based upon the assessment of existing information.
