Abstract
The paper evaluates the impact of river training works designed to address problems associated with fooding on the braided-wandering Belá River in Slovakian Carpathians. This impact was investigated after the food event in July 2018 on 11 river reaches where the river engineering and management intervention was applied. We analyzed its impact by spatio-temporal variations in river morphology (12 channel parameters) and changes in cross-section and hydraulic parameters (fow velocity, shear stress, stream power, W/D ratio) between pre- and post-food management periods. The research hypotheses related to decreasing geodiversity in managed river reaches, a rapid increase in fow velocity during an extreme food in river reaches where there is no sufcient foodplain inundation due to artifcially high banks built by river training works, and increasing erosive force in the channel zone thanks to river management intervention were confrmed. The intervention in the braidplain area of the Belá River resulted in an undesirable simplifcation of the river pattern, loss of geomorphic diversity, loss of channel–foodplain connectivity, and disturbance and restraint of hydromorphological continuity. Identifcation of main conficts of the Belá River management is important for clarifying the diferent approaches of stakeholders in the study area and aims to provide an objective illustration of their consequences. The presented analyses could help in future management issues as well as in the more critical decision-making process in vulnerable and rare braided river systems on the present when we are losing so many natural rivers by human decisions.
