ESTIMATING THE SPATIAL VARIABILITY OF SPECIFIC CAPACITY FROM A SWEDISH REGIONAL DATABASE

A regional database incorporating well information has been used to de termine likely values of parameters controlling groundwater flow in so uth-east Sweden based on an assessment of the specific capacity using geostatistics. Variography is the basis for geostatistical simulation conditioned by measurements of the specific capacity in local wells. I n the absence of sufficient data to develop a stochastic model for the hydraulic conductivity at depth, it is suggested that a general model describing its vertical distribution be adopted using profiles establ ished in deep wells, guided by conditionally simulated estimates.
