    Monitoring Preferential Flow During Infiltration Experiments

  • Original language description

    A study of the spatial and temporal variability of soil infiltration properties was conducted at the Liz experimental site, Sumava Mts., Southern Bohemia. The preferential flow occurring during the infiltration experiment was monitored by means of invasive and non-invasive visualization of flow paths. For the noninvasive visualization two geophysical methods were tested, namely TDR and ERT. In ERT images, the evolution of infiltration processes is clearly visible, however information about the preferential character of the flow is lost, due to the averaging nature of the method. This is clear from the comparison of ERT images with the images of Brilliant Blue dye distribution taken from the dug-out horizons at the end of infiltration.

    Sledování preferenčního proudění během infiltračního experimentu

  • Czech description

    V rámci studia časoprostorové variability infiltračních vlastností jsou prováděny infiltrační experimenty na experimentální ploše Liz, Šumava. Průběh infiltrace byl sledován užitím invasivních a neinvazivních metod. Zatímco invasivní metody jednoznačně potvrzují přítomnost preferenčního proudění, užité neinvazivní metody nejsou schopny tento fenomén zachytit adekvátně. Dvě geofyzikální neinvazivní metody byly testovány, ERT a TDR.
