Abstract:[en] Accurate dating is necessary to get insight in the temporal variations in sediment deposition in floodplains. The interpretation of such dates is however dependent on the fluvial architecture of the floodplain. In this study we discuss the fluvial architecture of three contrasting Belgian catchments (Dijle, Geul and Amblève catchment) and how this influences the dating possibilities of net floodplain sediment storage.

Abstract Carbon exchange associated with accelerated erosion following land cover change is an important component of the global C cycle. In current assessments, however, this component is not accounted for. Here, we integrate the effects of accelerated C erosion across point, hillslope, and catchment scale for the 780-km 2 Dijle River catchment over the period 4000 BC to AD 2000 to demonstrate that accelerated erosion results in a net C sink.

Abstract Holocene floodplain deposits are often used as environmental archives of terrestrial ecosystems, but often radiocarbon dating is problematic due to the absence of datable material. One of the possible alternatives is the use of floodplain contaminants, where the presence of contaminants in sediment indicates that these sediments were deposited after the initiation of contamination. The Geul river catchment (350 km²) is located in the loess region of eastern Belgium and southern Netherlands. Lead was probably mined since ...

In the Ardenne massif, several periods of increased sediment deposition have been identified during the last millennia. They can be correlated to increasing anthropogenic land use pressure. The majority of the sediments found in floodplains were deposited in the last 4000 years, and in many cases even in the last 1000 years.

Abstract Soil erosion and sediment deposition are important geomorphic processes in the central European loess belt. Several studies have shown that important changes in the rates of soil erosion and sediment deposition occurred during the Holocene. Sediment budget approaches are ideal tools to understand such complex system behavior during the Holocene. Within this study a temporal differentiated Holocene sediment budget based on field data was constructed for the Belgian Dijle catchment (870 km²), and compared with a ...

Abstract Processes like lateral river bed migration (meandering) and changes in width and depth of its bed are an essential part of the sediment dynamics of a river system. For a given time period, these processes can either be a net sediment source or sink within the catchments sediment budget. They also have a large influence on the preservation potential of floodplain deposits, and thus also on the value of river valleys as an environmental archive. This study concerns the importance of river channel processes within the Dijle ...

Recently, LIDAR imagery has become a very attractive tool to provide detailed information on fluvial morphology. This is especially the case were high-resolution imagery is recorded during local case studies. However, for several regions, LIDAR imagery with less-optimal conditions is now available. Here we tested the possibility to extract quantitative information on fluvial morphology and fluvial dynamics from regionally available LIDAR images for the River Dijle (Belgium). Two regional LIDAR datasets with different quality were available ...

Bodemerosie, en het transport en de afzetting van sediment zijn in veel gematigde streken belangrijke geomorfologische processen tijdens het Hol oceen, en riviersystemen zorgen hierbij voor een essentiële link tussen continenten en oceanen voor het transport van sediment. Diverse studies van West-en Centraal-Europese rivierbekkens tonen de dominante invloed van landbedekking op de sedimentdynamiek, terwijl de rol van klimatologi sche variaties onduidelijk is. De meeste van deze studies leggen relatie s ...

Sediment deposition in floodplains is an essential part of the sediment dynamics of a catchment. These sediment dynamics can vary largely on a Holocene time scale under the influence of driving forces such as land use and climatic variations. In this paper we review the Holocene floodplain sediment deposition history of rivers in West and Central Europe, with special attention to the influence of climate and land use variability. During the early Holocene (Preboreal to Atlantic Period), most floodplains were rather stable with limited ...
