Abstract:
This thesis analyses the morphology and fish habitats of two typical sections of the river Kamp in Lower Austria with different modelling software. The Kammern section is an epipotamal part of the Kamp. The consequences of anthropogenic actions for the habitat quality are analysed by modelling the geometries before and after the flood in 2002. In addition two historical geometries, one from 1890 representing the natural state of the river and one from the time after 1909, representing a regulated river, were simulated. The modelling was done with the models HEC-RAS and CASIMIR. This is the first time a complete numerical habitat simulation of a historical geometry was performed. The thesis is an important step to build a ¿Leitbild¿ of the Kamp river. Comparing the habitat quality for the nase and barbel in those four geometries, significant differences were found. The Stallegg section is an example for the hyporhithral. During the 2002 flood an anabranch was formed, the ecological impacts of which were analysed. By simulating this section with the programs CASIMIR and RIVER 2D the extremely positive ecological effect of the anabranch could be quantified and proved. It also turned out, that the two programs deliver similar results concerning the usable areas. The two dimensional hydrodynamic numeric model RIVER 2D shows a more realistic simulation and delivers more precise results.
