Abstract
Discharge dynamics in natural streams can be influenced by aquatic vegetation, therefore its precise evaluation is crucial for effective river management especially in lowland environments. This paper investigates the accuracy of discharge measurements in lowland natural streams with aquatic vegetation using an Acoustic Doppler Current Profiler (ADCP). The research highlights the challenges and issues of using ADCP in areas with aquatic vegetation, which cause measurement inaccuracies and deviations in the measuring sections. Field measurements carried out on the Gabčíkovo – Topoľníky canal stream during the growing seasons of 2018 and 2023 recorded differences in accuracy and calculated discharges and flow velocity attributes due to denser vegetation.
