In this research the complex spatial patterns of sediment transport and deposition are studied at the temporal scale of individual inundations and spatial scale of a small tidal creek basin (ca. 6 ha) within the salt Paulina marsh, Western Scheldt. Field measurements are used for the implementation and validation of 2-dimensional numerical models for tidal marsh sedimentation. Near the ...

However, there is no clear one on one relation between the intensity of human presence (population density) and the magnitude of impact on sediment transfers. Several thresholds have to be crossed for coupling between the various landscape elements in a river catchment to occur, ensuring that anthropogenic landscape disturbances impact ...

Soil Erosion in Europe, Oct 19, 2006
Soil erosion is a natural process, occurring over geological time, and most concerns about erosio... more Soil erosion is a natural process, occurring over geological time, and most concerns about erosion are related to accelerated erosion, where the natural rate has been significantly increased by human activity. Soil erosion poses severe limitations to sustainable agricultural land use, as it reduces on-farm soil productivity and causes the accumulation of sediments and agro-chemicals in waterways. In Europe, soil erosion is caused mainly by water and, to a lesser extent, by wind. Rill and inter-rill erosion affects the largest area, but evidence of ...

De alsmaar toenemende impact van menselijke activiteiten heeft echter geleid tot een nooit geziene afname van de diversiteit aan genen, soorten en ecosystemen. Soorten verdwijnen vandaag meer dan duizend keer sneller dan de afgelopen miljoenen jaren. De oorzaken zijn habitatverlies en-fragmentatie, vervuiling, de invasie van exotische soorten, overbejaging en-bevissing, en, eerder recent, klimaatsverandering. De dramatische ...

By removing the most fertile topsoil, erosion reduces soil productivity and can, where soils are shallow, lead to an irreversible loss of natural farmland. Severe erosion is commonly associated with the development of temporary or permanently eroded channels or gullies that can fragment farmland. The soil removed by runoff from the land, during a large storm, accumulates below the eroded areas, in severe cases blocking ...

Abstract The AnnAGNPS model, widely utilized as a practical tool for addressing erosion problems ... more Abstract The AnnAGNPS model, widely utilized as a practical tool for addressing erosion problems and land use planning, was implemented in a small agricultural watershed located in central Belgium, to assess its prediction capacity of runoff, peak flow and sediment yield in humid temperate conditions. Model performance was evaluated at the event scale by using a database reporting hydrological, geomorphologic and land use data collected during a 2-year period. Seventeen events were modelled and compared with the corresponding ...

This is crucial to assess the reliability of average SY values for a given measuring period (MP) and is of great geomorphic significance. This paper aims to bridge this research gap. Materials and methods A worldwide database was compiled with time series of measured SY values. ...

In this paper we date floodplain and colluvial deposition in the Belgian Dijle catchment using accelerator mass spectrometric radiocarbon and optical stimulated luminescence dating. Relative mass accumulation curves for the Holocene were constructed for three colluvial sites and 12 ...
