Validation of a Novel, Shear Reynolds Number Based Bed Load Transport Calculation Method for Mixed Sediments against Field Measurements
Autor: Gergely T. Török, János Józsa, Sándor Baranya
Publikováno v: Water, Vol 11, Iss 10, p 2051 (2019)
In this study, the field measurement-based validation of a novel sediment transport calculation method is presented. River sections with complex bed topography and inhomogeneous bed material composition highlight the need for an improved sediment tra

A Shear Reynolds Number-Based Classification Method of the Nonuniform Bed Load Transport
Autor: Gergely T. Török, János Józsa, Sándor Baranya
Publikováno v: Water, Vol 11, Iss 1, p 73 (2019)
The aim of this study is to introduce a novel method which can separate sand- or gravel-dominated bed load transport in rivers with mixed-size bed material. When dealing with large rivers with complex hydrodynamics and morphodynamics, the bed load tr

2D vs. 3D Numerical Approaches for Fish Habitat Evaluation of a Large River — Is 2D Modeling Sufficient?
Autor: János Józsa, Vivien Füstös, Tibor Erős
Publikováno v: Periodica Polytechnica Civil Engineering.
Computational Fluid Dynamics is an effective tool for assessing non-present conditions, thus also in habitat evaluation within ecohydraulics. Deciding whether to apply a one-, two- or three-dimensional numerical approach, is an optimization that need

Investigation of the Effects of Ship Induced Waves on the Littoral Zone with Field Measurements and CFD Modeling
Autor: Gábor Fleit, Sándor Baranya, Nils Rüther, Hans Bihs, Tamás Krámer, János Józsa
Publikováno v: Water, Vol 8, Iss 7, p 300 (2016)
Waves induced by ship movement might be harmful for the habitat in the littoral zone of rivers due to the temporally increasing bed shear stress, the high-energy breaking waves and the consequently related detachment of benthic animals. In order to u

Assessment of CFD Model Performance for Flows around a Hydraulic Structure of Complex Geometry
Autor: Péter Grivalszki, Gábor Fleit, Sándor Baranya, János Józsa
Publikováno v: Periodica Polytechnica Civil Engineering.
Computational Fluid Dynamics (CFD) modeling has become a widely used research tool in the hydraulic engineering community, however, for many problems the numerical model setup and even the selection of the suitable hydrodynamic solver is still a chal
