Description	Within the framework of the research of preferential flow in clay-loam soil at Valecov site in Bohemo-Moravian highland, field ponded infiltration experiment monitored by TDR and resistivity tomography. TDR method was able to detect slow water content increase throughout the infiltration; however, it was not able to detect all the water added to the soil right from the start of the experiment. The resistivity tomography was performed using ARES system. The results imply that the measuring technique in its present state is not suitable for the clay soil. The outputs of the geophysical methods were found inconclusive. At the end of the infiltration experiment, a dye tracer and excavation was used to visualize the flow paths. The tracer was found to infiltrate about 4 times deeper than predicted based on the tracer volume, assuming flow in fully saturated soil. The findings from the field measurements were validated in laboratory experiments using undisturbed samples of the soil.
