Abstract

Spatial variability of soil heterogeneity is important to consider for soil water and solute transport. The results of the present work indicated that spatial heterogeneity affects all investigated soils (soils in Japan, Sweden, Tunisia, and China). Experimental data indicated a high degree of bypass or preferential flow within small plots and non-sigmoid breakthrough curves suggesting tailing phenomena and immobile fractions of soil water. The present work supports the dual-porosity hypothesis. But findings also indicate that the observation scale is important to consider when averaging the process in time and space.
