About article:
This contribution deals with the evaluation of bed silts permeability in Komárňanský channel, the biggest channel from channel network at Žitný ostrov (ŽO). The bed silts permeability in ŽO channel network significantly impacts the mutual interaction between channel network and groundwater at ŽO and is expressed by parameter of their saturated hydraulic conductivity. The paper compares the values of saturated hydraulic conductivity of bed silts which were extracted from Komárňanský channel at ŽO during period 1993–2016. The bed silts were extracted and obtained by two ways, as disturbed samples and as undisturbed samples. From disturbed samples in Komárňanský channel were obtained saturated hydraulic conductivity values of bed silts calculated according to Bayer-Schweiger and Špaček – Tab. 1, the valid values Kp reach from 1,917.10-06 – 6,094.10-05 m.s-1. From undisturbed samples of silts which were extracted along Komárňanský channel from top, middle and bottom layer of silts, were determined values of saturated hydraulic conductivity Kn measured in laboratory - by falling head method. These values for Komárňanský channel in 2016 are illustrated in Tab. 2. The values Kn for Komárňanský channel reached values from 4,721.10-07 – 1,255.10-05 m.s-1.
