Where measured data are unavailable, numerical models emerge as valuable tools for predicting flash floods. Recent applications of various hydrological and hydrodynamic models to predict overland flow have highlighted the need for improved representations of the complex flow processes that are inherent in flash floods. This study aimed to identify an optimal modeling approach for characterizing leaf litter losses during flash floods. At a gauged watershed in the Hidegvíz Valley in Hungary, a physical-based model was calibrated using two distinct rainfall–runoff events. Two modeling methodologies were implemented, integrating canopy interception and leaf litter storage, to understand their contributions during flash flood events. The results from the model’s calibration demonstrated this approach’s effectiveness in determining the impact of leaf litter on steep-sloped watersheds. Soil parameters can estimate the behavior of leaf litter during flash flood events. In this study, hydraulic conductivity and initial water content emerged as critical factors for effective parametrization. The findings underscore the potential of a hydrodynamic model to explore the relationship between leaf litter and flash flood events, providing a framework for future studies in watershed management and risk-mitigation strategies.}, year = {2024}, eissn = {2073-4441}, orcid-numbers = {Ámon, Gergely/0000-0002-3125-1473; Bene, Katalin/0000-0001-9285-9477; Gribovszki, Zoltán/0000-0003-3061-8912; Kalicz, Péter/0000-0003-0010-9519} } @CONFERENCE{MTMT:34589191, title = {A Methodology for Life-Cycle Assessment of Blue-Green Infrastructure in the Green City Development Program}, url = {https://m2.mtmt.hu/api/publication/34589191}, author = {Kálmán, Attila and Bene, Katalin}, booktitle = {Waste Management, Circular Economy and Business 2023}, unique-id = {34589191}, year = {2023}, pages = {109-109}, orcid-numbers = {Kálmán, Attila/0000-0002-0674-6415; Bene, Katalin/0000-0001-9285-9477} } @{MTMT:34574687, title = {Infiltration and soil moisture measurements in an experimental parcel}, url = {https://m2.mtmt.hu/api/publication/34574687}, author = {Koch, Dániel and Majer, Fruzsina Kata and Dobos, Endre and Bene, Katalin}, booktitle = {HydroCarpath 2023 : Hydrology of the Carpathian Basin: Catchment Experiments and Modeling for Improved Description and Prediction of Hydrological Processes}, unique-id = {34574687}, abstract = {With changing weather conditions, understanding the infiltration process is increasingly important. The Faculty of Water Sciences of the University of Public Service in Hungary created an experimental catchment area in the East Mecsek Hill along the Völgységi stream to measure the elements of the rainfall-runoff process. An infiltration experiment was recently carried out in the irrigation parcel to determine the infiltration curve and better understand the infiltration process. During the infiltration experiment, measurements were combined with multi-level soil moisture probes to determine the water content in different soil layers. Throughout the infiltration measurements, two multi-level soil moisture meters were placed within the experimental plot to collect soil moisture data at 10, 20, 30, 40, 60, and 100 cm depths. The results show that the top soil layer has the highest moisture content. There is a clay layer at a depth of about 30–40 cm a with better water-holding capacity and lower water conductivity. Between 60 and 100 cm, the sandy soil-forming rock still receives a small water recharge when intense rainfall occurs, but this layer is slow to respond to surface inputs. In situ and laboratory samples were taken to determine the soil hydraulic parameters.

Recently, an extreme drought caused record low water levels in Lake Velence, Hungary, that undermined recreational tourism around the lake, thereby triggering conflicts between water users within the catchment. Water managers’ efforts to find solutions require reliable lake water level predictions. This poster invites researchers, engineers, and enthusiasts to participate in a scientific challenge of predicting the water levels of Lake Velence at the beginning of each month during 2024. To participate in the challenge, one must estimate the daily water levels for the upcoming month. Past data for the 2002-2022 period will be provided, including catchment characteristics and the operational rules of the hydraulic structures, stage and flow measurement in the catchment area, and the lake’s current official water budget calculation method. Considering the known uncertainties of the current calculation method, participants are encouraged to develop their own unique method to determine lake water levels. Initial water levels and meteorological forecasts for the basin area will be given at the beginning of each month. The monthly winner is the one whose prediction results in the lowest root mean squared error. The overall champion of the challenge is the one with the most monthly wins throughout the year.}, year = {2023}, orcid-numbers = {Bene, Katalin/0000-0001-9285-9477} } @inproceedings{MTMT:34219726, title = {A Velencei-tavi vízmérlegszámítás záróhibáinak elemzése és a számítási módszertan felülvizsgálata}, url = {https://m2.mtmt.hu/api/publication/34219726}, author = {Chappon, Máté and Bene, Katalin}, booktitle = {Magyar Hidrológiai Társaság XL.

Jelen kutatásban az elmúlt 37 évre rendelkezésre álló havi rendszerességű vízmérleg számítás adataiból indulunk ki. A számítás záróhibája a számított és a megfigyelt tóbeli vízszint különbségeként kerül meghatározásra. A záróhibák vizsgálatából kiderült, hogy az 1970-es évek végén kidolgozott és jelenleg is alkalmazásban levő számítási módszertan több bizonytalansággal terhelt. E bizonytalanságok hatására a záróhibák jellemzően negatív értéket vesznek fel, azaz a számított vízszintek jellemzően alacsonyabbak, mint az agárdi vízmércén mért szintek. A tanulmányban feltárjuk a vízmérlegszámítás záróhibáinak lehetséges okait és javaslatot teszünk a módszertan továbbfejlesztésére.
