Carbon exchange associated with accelerated erosion following land cover change is an important component of the global C cycle. In current assessments, however, this not accounted for. Here, we integrate effects across point, hillslope, and catchment scale for 780-km 2 Dijle River over period 4000 B.C. to A.D. 2000 demonstrate that results in a net sink. We found long-term sink be equivalent 43% eroded have offset 39% (17–66%) emissions due anthropogenic since advent agriculture....
Abstract The potential for geomorphological mapping and quantitative calculations of light detection ranging (LiDAR) data within fluvial geomorphology was studied two river catchments Belgium (Dijle Amblève), which differ in physical settings floodplain morphology. Two commercial, of‐the‐shelf LiDAR datasets with different specifications (horizontal resolution vertical accuracy) were available parts the floodplains both catchments. Real‐time kinematic (RTK) Global Positioning System (GPS)...
Glacial−interglacial variations in CO 2 and methane polar ice cores have been attributed, part, to changes global wetland extent, but the distribution before Last Glacial Maximum (LGM, 21 ka 18 ka) remains virtually unknown. We present a study of peatland extent carbon (C) stocks through last glacial cycle (130 present) using newly compiled database 1,063 detailed stratigraphic records peat deposits buried by mineral sediments, as well model. Quantitative agreement between modeling...
Abstract Natural and human‐induced erosion supplies high amounts of soil organic carbon (OC) to terrestrial drainage networks. Yet OC fluxes in rivers were considered global budgets only recently. Modern estimates annual burial inland river sediments 0.6 Gt C, or 22% C transferred from ecosystems channels, consider lakes reservoirs disregard any long‐term hillslope floodplain sediments. Here we present the first assessment sediment‐bound storage Central Europe a synthesis ~1500 Holocene...
Abstract. Colluvial soils are enriched in soil organic carbon (SOC) comparison to the of upslope areas due deposition and progressive burial SOC. This SOC has important implications for global cycle, but long-term dynamics buried remain poorly constrained. We addressed this issue by determining efficiency (i.e. fraction originally deposited that is preserved colluvial deposits) as well stability soils. quantified turnover rate establishing sediment chronologies. The was derived from...
Fluvial architecture changed under the influence of increasing human impact throughout Holocene in many north-west European catchments. Typically, peat formation – a marshy environment during Early and Middle is replaced by clastic overbank deposition. In this study we show importance detailed chronology floodplain changes, with an example from Belgian Dijle catchment. total, 45 radiocarbon ages 15 alluvial sites were used. Cumulative probability functions made base (16 samples) top (29...
Abstract Floodplain deposition is an essential part of the Holocene sediment dynamics many catchments and a thorough dating control these floodplain deposits therefore to understand driving forces dynamics. In this paper we date colluvial in Belgian Dijle catchment using accelerator mass spectrometric radiocarbon optical stimulated luminescence dating. Relative accumulation curves for were constructed three sites 12 alluvial sites. A database was all available ages analysed relative rates...
Abstract Accurate dating is necessary to get insight in the temporal variations sediment deposition floodplains. The interpretation of such dates however dependent on fluvial architecture floodplain. In this study we discuss three contrasting Belgian catchments (Dijle, Geul and Amblève catchment) how influences possibilities net floodplain storage. Although vertical aggradation occurred all floodplains during last part Holocene, they differ importance lateral accretion entire Holocene....
Floodplain deposition rates have increased markedly under influence of human impact throughout the late Holocene in many western and central European catchments. Consequently geomorphology ecology floodplains changed. In this study we discuss its on floodplain geoecology during middle for headwaters Dijle catchment, located Belgian loess belt. The regional vegetation was reconstructed from sedimentological palynological analyses. An age–depth model studied sequences obtained using 17...
This study presents a Holocene sediment budget for the Valdaine Region, located at edge of southern French Pre-Alps. colluvial and alluvial deposition are quantified based on existing new field data. Average thickness values were calculated different landscape units, available chronological data used to make time-differentiated budget. Total in (334 km 2 ) amounts 167 × 10 6 m 3 , while Roubion Jabron catchments (in total 610 including their catchment upstream Valdaine) 177 . Especially, is...
