Toelichting (Engels) Lowland streams are being restored to their natural situation throughout Europe. However, a lot of projects do not meet their goals. Furthermore, there is a knowledge gap on the restoration demands and the current understanding on the morphodynamics of low-energy streams. The focus of this thesis is on the morphodynamic evolution of the lowland stream the Dommel, in The Netherlands. The Dommel is located in the Roer Valley Graben and flows in the sandy deposits of the Boxtel formation. Due to the subsidence of the Roer Valley Graben, it is a good location to study sediment deposits. The used methods, are a combination of literature, Ground Penetrating Radar (GPR), auguring and Optical Stimulated Luminescence (OSL) dating. The results indicate a succession that started with a braided system during the Pleniglacial, to a large meandering system in the Late Glacial. Towards the end of the Younger Dryas the large meanders were abandoned and the system shifted to a lower energetic meandering system and eventually an immobile system. The stream kept its immobile river pattern until anthropogenic land use affected the stream by increasing the stream power, causing the Dommel to transit to a more energetic meandering pattern during the Bronze Age (Late Subboreal). It is concluded that the Dommel would have remain lateral immobile, if there were no anthropogenic influences in the catchment.
