Samenvatting (EN)

PROJECT AIM: River flow within undulated flood planes is difficult to forcast because of the complex flow geometry founded by main channel and groyne fields. In the flood plane there are many obstacles and landforms, which requires high demand for numerical modeling. Due to large computational domain and limitation of computer capacity, complete details can generally not be resolved. This study focuses on correct representation of resistance elements in a numerical simulation and consistent behavior towards high water stages. A number of prosesses related to vegetation, weirs and bed- forms will be studied in great detail in order to come to an improved implementation of physical processes.
