Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The objective of this study was to investigate chemical contaminants penetrated into groundwater through macropores in the vazone zone. A total of 4 experiments with various ponding depths were conducted. With a combined method, dye and iodine-starch staining were used to visualize soil macropore and soil water flow patterns, respectively. Flow patterns with a low infiltration amount were similar to the macropore patterns and macropores were the main factor to control the flow patterns. As the infiltration amount increased, flow patterns were influenced by both macropores and boundary conditions. Soil water flow patterns became more heterogeneous as the heterogeneity of macropores increased. Stained patterns played a much important role in redistribution of infiltration water than the soil saturation change in the stained region. The contaminants concentration decreased dramatically in the upper depth and then the decreasing trend was slowed down.
