The spatial heterogeneity is an inherent feature of site conditions with significant functional implications. Water table depth was measured monthly for 6 years.
Results show that spatial patterns of site conditions are highly variable.
Temporal fluctuations in the surface water tables of all sites were also highly variable. Analyses of the data show that GIS and geostatistical applications are powerful tools, not only for storing digital objects, but also for spatial and temporal analyses of the interrelationships among these objects.
