Modeling hydraulic resistance of floodplain vegetation

In this thesis, methods are investigated that describe the impact of vegetation on a flow field, and their potential for application in river-reach hydraulic computational models. This field of research is of great importance to river flood studies, as vegetation-covered foodplains commonly become part of the river flow section during high-discharge conditions. In this respect, the obstruction of vegetation to flow needs to be taken into account if trying to predict overall flow behavior. To describe the impact of vegetation on a river-reach scale, ob- structing vegetation should be incorporated in terms of easily measurable input parameters and require only minimal additional computational effort. In the current work, such a method is proposed.
