ABSTRACT:
Our paper presents the results of determining temporal variability in the water table depth in topohydrosequence of Retisols/Luvisols and Phaeozems/Gleysols. Assessing temporal variability in the water table was done using geostatistical and statistical methods. The mean annual water table depth in soils occupying higher locations in the relief were determined by precipitation in the given and previous years, but in soils of footslope only by precipitation in a given year. Water table fluctuations were characterized by a clearly visible temporal structure and low values of random variability. The range of time correlation of water table was dependent on the relief and was shorter in soils located in lower parts of the topohydrosequence and longer in wells in the higher part. The contribution of the nugget effect in variance was also dependent on the location of wells on the slope. The obtained values of the fractal dimension (D) show a distinct relationship between D and the location of soil in the topohydrosequence. The values of multivariate analysis indicated that the statistical and geostatistical parameters applied to assess temporal variability of water table depth were dependent on the soil (well) location in the relief.
