Field measurements with Polish colleagues in the Morávka River

The research of the Morávka Canyon continued during the first week of August, when colleagues from the Cracow Agricultural University, namely Prof. Radecki-Pawlik and Dr. Plesinski visited this locality. We focused on detailed hydraulic measurements and geodetic survey of channel-reaches containing large artificial boulders (mainly from destroyed rip-rap structures). This could help us to answer the question, whether these boulders prevent from further erosion or potentially accelerate erosion processes via concentration of water flows. Additional measurements of present bed sediments and old gravels hanging on canyon walls provided information about changes in the river transport capacity.
