Measurement and calculation of the seepage between river and fluvial sediments

EN This diploma thesis deals with the measurement of seepage between the river and fluvial sediments using seepage meters. Although this is not a new method, it has never been widely used to measure seepage in our country. The Morava River and its side channels (Malá Voda and Mlýnský potok) in the Litovelské Pomoraví region were chosen as the test location for this measurement. In this locality, conflict of interests between groundwater extraction and the protection of the of floodplain forests habitat has been ongoing for a long time. Data of the seepage intensity would be very helpful for the overall understanding of the groundwater flow and influence of water from rivers in this territory. The work also includes a numerical model of groundwater flow, which was used to verify the measured seepage values. Due to the overall complexity of the geological structure and groundwater flow, the model includes a wide area around the site of interest. In addition to the scope of the work, two more control measurement campaigns were carried out to verify the overall functionality of the devices. First of them took place on the Morava River near Kojetín, on the occasion of a pumping test carried out as part of the VUV TGM project. The bottom of the river is at a depth of 3.5 m below the surface, the aim of..
