Two Awards at the ERB Conference 2026 in Hungary

At the 20th Biennial Conference of the Euro-Mediterranean Network of Experimental and Representative Basins (ERB), held from 7 to 10 July 2026 at the Faculty of Water Sciences of the Ludovika University of Public Service in Baja, Hungary, two contributions from researchers at the Institute of Hydraulic Engineering and Water Resources Management at TU Wien were awarded.

The conference focused on the role of small experimental catchments in research and education, as well as on the exchange of recent developments in the fields of hydrological monitoring, modelling, erosion, and sediment transport.

Borbála Szeles received the award for the best presentation for her contribution Rain Drop Size Distribution Linked to Soil Erosion in the Hydrological Open Air Laboratory (HOAL), Austria. The study investigates the relationship between rainfall characteristics, particularly raindrop size distribution, and soil erosion in the Hydrological Open Air Laboratory (HOAL), a 66 ha densely instrumented and tile-drained agricultural research catchment located in Lower Austria.

The results show that, during winter, rainfall events with low kinetic energy can still lead to high sediment loads due to bare and saturated soils. In spring and summer, larger and faster raindrops, as well as land use and soil moisture conditions, play an important role in erosion processes. Furthermore, the study highlights the potential of disdrometer measurements for investigating rainfall characteristics relevant to erosion.

Dušan Marjanović received the award for the best poster for his contribution Evaluation of Grassed Waterways in a Small Austrian Catchment through Hydrodynamic Modelling. Grassed waterways are a nature-based solution to reduce surface runoff and soil erosion in agricultural catchments. The study investigates their effectiveness in the HOAL using a hydrodynamic modelling approach.

The grassed waterways were installed in early 2023 along the natural drainage pathways of the agricultural hillslopes. Using a calibrated coupled surface-subsurface HydroGeoSphere (HGS) model, rainfall events before and after the installation were analysed to quantify the impact of these measures on flow behaviour, sediment retention, and water storage within the catchment. The study aims to investigate the influence of different initial, antecedent, and land-use conditions in order to improve the understanding of grassed waterway behaviour.
