Following the flood in 2002 at the Kamp river in Lower Austria, this thesis was written in order to derive a better estimation of the influence of vegetation on hydraulics during floods. Therefore different vegetation scenarios were examined in a physical model. This work specially deals with the construction and measuring technology of the physical model (innovative model-construction-concept) and the hydrodynamic-numerical modelling. New and uncommon materials which offer some advantages over a conventional type of construction were used. In the physical model thirteen vegetation scenarios were analysed using three different slopes (1 ‰, 2 ‰ and 4 ‰) and three different flood-discharges (HQ30, HQ50 and HQ100). With the numerical model control- and additional calculations were carried out. For modelling the vegetation, different approaches were used. In order to be able to quantify the velocity distribution in a cross section during a flood event in a better way, water velocities were measured and graphically represented. It was shown that a numerical model can also be used for small systems like hydraulic scale models. With reference to the innovative model-construction-concept, important knowledge and experience has been collected. Numerical models, if well calibrated, can represent useful tools for modelling real-world systems. If possible, physical and numerical models should not exclude themselves, but rather be used simultaneously.
