We participated the river restoration conference in Cracow

Tomáš Galia, Jan Hradecký and Václav Škarpich participated the conference 'Towards the Best Practice of River Restoration and Maintenance', which took place 20-23/9 in Cracow (PL) under organisation of Ab Ovo Association, Institute of Water Engineering and Water Management, Krakow University of Technology, University of Agriculture in Krakow, Institute of Nature Conservation, Polish Academy of Sciences in Krakow, Institute of Geography, Pedagogical University of Krakow and Regional Water Management Board in Krakow. Tomáš Galia spoked about effects of check-dams on channel morphologies and bed sediment parameters and he also presented some possibilities to restore such type of managed streams. Václav Škarpich discussed the role of human impact connected with the increase in stream power in managed gravel-bed rivers. Many interesting topics were presented through the conference, which dealt with natural function of rivers, ecosystem services and river restorations (see the book of abstracts free available for download).  

The 3-day field trip took place immediately after the conference in a smaller group of scientists. Colleagues from Poland showed us their study locations (e.g. Czarny Dunajec, Kamienica, Biala, Bialka), where we could see incision tendencies of Carpathian gravel-bed rivers as same as 'close-to-natural' reaches with wandering river patterns and development of islands or a mountain stream with log-jams. Also the approaches of local river restorations or a flood hazard by instream wood transport were illustratively demonstrated in the field. This trip was held in a very friendly atmosphere, giving us a great opportunity to discuss (not only) the issues of gravel-bed streams with well-known colleagues from abroad. We would like to thank especially to Bartek Wyzga and Joanna Zawiejska for the preparation and organisation of this field trip and conference.
