A Critical Evaluation of Single Extractions from the SMT Program to Determine Trace Element Mobility in Sediments
Published 2012-01-01“…Two commonly applied single extractions procedures, namely extractions with ammonium-EDTA and acetic acid, were evaluated based on the analysis of 72 samples from alluvial sediments. For most trace elements (Cu, Zn, Cd, Ni, As, and Pb), a significant linear relationship could be established between their ammonium-EDTA or acetic acid extractable concentrations and their total concentrations, the organic carbon content, pH, and Fe , Al, and/or Ca content in the sediments. …”

Subsurface geology of the Torino metropolitan area (Westernmost Po Plain, NW Italy)
Published 2024-12-01“…Our results demonstrate that the deposition of the lower Piacenzian shallow marine succession and then of the Piacenzian to Calabrian alluvial record was controlled by the stepwise propagation of the THF, and suggest that this thrust was apparently sealed by the late Early Pleistocene unconformity. …”

Le port antique de Chelles (Seine-et-Marne) : une course après la rivière
Published 2020-12-01“…The general development reflects a rapid decline in activity in connection with the gradual flooding of the Marne channel, due to massive alluvial inflows. The latter are related to erosion due to the development of agriculture across the Marne watershed, which also led to the establishment of an increasingly marked flood regime. …”

The paradox when managing the riparian zones of rivers with engineered embankments in The French prealps
Published 2014-07-01“…The current management of these embankments often excludes woody plants for safety reasons. However, alluvial vegetation and riparian zones can play important ecological roles by providing often very biodiverse environments and acting as biological corridors.There is a paradox when managing these embankments between the security requirement to exclude woody plants and the ecological imperative to add vegetation. …”
