The estimation of hydraulic conductivity and other correlation scales by traditional geostatistical methods requires a large number of field measurements at appropriate horizontal and vertical spacings. In order to extend the application of stochastic subsurface hydrology analysis to situations where such data are limited we propose an approach to correlation scale estimation that incorporates geological mapping. Regions of the formation with hydraulic conductivity values above (or below) some specified cutoff value are mapped and their dimensions are related to the correlation scale, by means of threshold‐crossing theory.
