Abstract:In 2005 the water boards Velt and Vecht (now Vechtstromen) and Groot Salland (now Drents Overijsselse Delta) took over the management and maintenance of the Overijsselse Vecht from Rijkswaterstaat (Ministry of Infrastructure and the Environment). Since that moment the water boards have obligated themselves to meet the guidelines for the Vecht according to inter alia the Water Framework Directive WFD and Natura 2000. This obligation was proposed in 2009 in the ‘Vechtvisie 2009’, which is about the redevelopment of the canalised Vecht into a living half-natural lowland river. This includes meandering, sedimentation and erosion processes. After implementation of several measures more dynamics will be created. Based on several different alternatives (Wolfert et al., 2009a) and hydraulic simulations, a preferred alternative was accomplished. Water board Vechtstromen wanted an indication of the amount of sedimentation and erosion, where these processes would take place in the preferred situation over a period of 35 years and what the effect is on the prerequisites for safety and recreational navigability. The main objective of this research is: Analysing and understanding the morphological processes in the Overijsselse Vecht and quantifying the morphological consequences for bed and water level changes for the preferred alternative by using a SOBEK 3 model.
