Toelichting (Engels) A large part of the total sediment transport in a river occurs as fine sediment transport. During its transport through the river system fine sediment can be temporarily stored on the floodplain or in the channel bed. Besides playing a large part in the sediment budget of a river, storage of fine sediment in the gravel bed can also affect the ecology of a river. There can be contaminants attached to the sediment and infiltration of fine sediment in the gravel bed can reduce oxygen levels and limit nutrient exchange by clogging the pores. In this study, the infiltration and storage of fine sediment in a gravel bed was measured in the Geul River catchment in Limburg, the Netherlands. In addition, the distribution of zinc and lead contamination in the catchment was assessed. The fine sediment, transported by the Geul River, contains zinc and lead, due to historical mining activities.
