Das Projekt "Effects of human impact on floodplain soil functioning. Roles of fungi, fauna and soil organic matter on soil structure functioning in restored alluvial soils" wird vom Umweltbundesamt gefördert und von Universite de Lausanne, Institut de Geologie et Paleontologie durchgeführt. In the present project, we aim to study the very first processes of soil structuring to evaluate river restoration that plays a major role in environmental management and policy decisions, mainly due to increasing flood events. Agreement on what constitutes a successful restoration project continues to be lacking, and the relevant and novel approach proposed here will be the association of morphological and biological aspects of the soil structure. While the morphological approach (study of macro- and microstructure by the use of thin plates, soil aggregate stability measurements) takes into account the evolution of the soil in relation to the general climate, the biological one (fungal communities, earthworms, enchytraeids, organic matter) may help us to understanding soil organic matter incorporation. Moreover, we propose to validate these considerations by comparing them with the evolution of relatively undisturbed systems that may be considered as close approximations of conditions prior canalization.
