Abstract:Zervakis (2015) has developed a physics based model that approximates bed level in single river branches, based on parameters like: river slope, discharge, river curvature and river width. This physics based model is developed to support the interpolation of measured data. Fusing results from interpolation and the physics based model reduces the necessary amount of measured data to get bed level approximation with certain accuracy. This thesis study has focussed on extending the rapid assessment tool in such a way that the bed level at river bifurcations can be approximated. Two main goals set: Firstly, describe a bifurcation quantitatively and assessing which parameters are affecting the bed level around a bifurcation. Secondly, assess the performance of interpolation methods that describe the bed level around a bifurcation. The main research question of this thesis is: What is a method to approximate the bed level of an alluvial river bifurcation if data are scarce and how well does this method perform?
