Abstract

This study focuses on the impact of land consolidation and changes in landscape structure on medium term soil erosion and landscape morphology within a field located in a part of the Quincampoix watershed, southwestern Parisian Basin, France. The area was consolidated in 1967 and the AA. used the 137Cs-technique to quantify soil erosion for the period (1954-2009). The results showed that tillage processes dominated the soil redistribution in the study area for the last 55 years. Furthermore, the AA. demonstrated that soil redistribution was largely affected by the presence of current and also former field borders. They also showed that the use of an accurate DEM resulting from LIDAR data, based on present-day topography, leads to the underestimation of soil redistribution rates by the model, especially in this landscape submitted to recent and important morphological changes. These results have important implications for the simulation of tillage erosion processes and the understanding of soil redistribution processes in complex cultivated areas
