  abstract =     "There is an increasing awareness that rivers need more
                 room in order to safeguard flood safety under climate
                 change conditions. Contemporary river management is
                 creating room in the floodplains and allowing, within
                 certain bounds, natural processes of sedimentation and
                 erosion. One of the aims is to restore dynamic
                 conditions, so as to get a sustainable and more diverse
                 river ecosystem that can cope with floods. This new
                 approach requires understanding of the interaction
                 between the biotic and abiotic components of river
                 systems. More specifically, it requires a better
                 understanding of the interaction between flora and
                 fauna and geomorphological factors. This is the object
                 of investigation of the interdiscipline of
                 biogeomorphology. Modelling biogeomorphological
                 processes in river floodplains is the topic of this

                 To reduce flood risks in the Netherlands, measures to
                 increase the flood conveyance capacity of the Rhine
                 River will be implemented. However, it is expected that
                 floodplain sedimentation and softwood forest
                 development in rehabilitated floodplains will gradually
                 reduce the conveyance capacity and the biodiversity.
                 Moreover, in regulated rivers, such as the Rhine River,
                 erosion and sedimentation processes caused by channel
                 migration, which periodically interrupt vegetation
                 succession, cannot be allowed. Therefore, a floodplain
                 management strategy was proposed that would meet both
                 flood protection and nature rehabilitation objectives.
                 This strategy, 'Cyclic Floodplain Rejuvenation (CFR)',
                 aims at mimicking the effects of channel migration by
                 removal of softwood forests, by lowering floodplains or
                 by (re)constructing secondary channels. In chapter 2,
                 the effects of CFR measures on reducing flood levels
                 and enhancing biodiversity along the Waal River were
                 assessed. A one-dimensional hydraulic modelling system,
                 SOBEK, was applied together with rule-based models for
                 floodplain vegetation succession and floodplain
                 sedimentation. The model simulations demonstrated that
                 the flood management strategy of Cyclic Floodplain
                 Rejuvenation is able to sustain safe flood levels in
                 the Waal River. Rejuvenation is then needed every 25 to
                 35 years on average, each time in an area of about
                 15percent of the total floodplain area. The
                 rejuvenation strategy led to a diverse floodplain
                 vegetation distribution that largely complies to the
                 historical reference for the Waal River. Cyclic
                 Floodplain Rejuvenation may be the appropriate answer
                 to find symbiosis between flood protection and nature
                 rehabilitation in highly regulated rivers.
