“…The fractionations include NaOH-extractable P, HCl-extractable P, organic P, inorganic P and concentrated-HCl-P (Ruban et al, 1999(Ruban et al, , 2001. The SMT protocol has been used to understand the origin and solubility of sedimentary P by the limnological and marine geochemists, and also applied to analyzed the P fractions in soil and sewage sludge samples (González Medeiros et al, 2005;Lair et al, 2009;Zehetner et al, 2008;Xie et al, 2011;Zhu et al, 2013). This method has the advantages of simple operation, easy accessible reagent, and less interference between various forms.…”

“…In previous studies on a young floodplain at the Danube River in Austria, we found trends of P transformation and sorption (Lair et al, 2009a) as well as Cu and Cd retention (Graf et al, 2007;Lair et al, 2008) along with changes of Fe oxide crystallinity. More recently, we linked Fe oxide crystallinity to measured soil age (Lair et al, 2009b), which allows calculation of process rates.…”

“…The age of individual soil depth layers was estimated using a chronofunction that relates Fe oxide crystallinity in the soils (Fe o /Fe d ) 1 to soil age measured with 137 Cs and optically stimulated luminescence ( Fig. 2; Lair et al, 2009b). The studied soil profiles revealed various episodes of sediment deposition and soil formation.…”

Rates of biogeochemical phosphorus and copper redistribution in young floodplain soils

et al. 2009

Abstract. Nutrients and trace metals in river-floodplain systems may originate from anthropogenic activities and/or geogenic sources. Here, we analyze a soil chronosequence (2 to approximately 600 years) on a floodplain at the Danube River (Austria) to quantify the rates of P and Cu redistribution among biogeochemical pools during early soil formation under temperate continental climate. While bulk and clay mineralogy remained unchanged over the studied age gradient, we found considerable (mostly non-linear) redistribution of P and Cu among biogeochemical pools. The calcium-associated P and Cu fractions decreased rapidly during the initial decades of soil formation. The dissolution of calcium-associated P was mirrored by marked accumulation of organic P. Copper incorporated within resistant minerals showed a relative enrichment with soil age. The mean dissolution rates of calcium-associated (primary mineral) P decreased exponentially with increasing soil age from ∼1.6 g m −2 yr −1 over ∼15 years to ∼0.04 g m −2 yr −1 over ∼550 years, and were almost an order of magnitude higher than rates reported for tropical environments. Our study demonstrates that on riverine floodplains, rapid biogeochemical transformations can occur within the first centuries of soil formation under temperate climatic conditions.

“…Hydromorphological dynamics, chemical pollutions and depositional processes were strongly impacted by diking along the main channel and disconnecting of lateral channels since the beginning of the 19 th century (Tümmers, 1999). Several studies have focused on the storage and remobilization of heavy metals (Ciszewski and Gryar, 2016;Falkowska et al, 2016;Grygar and Popelka, 2016;Schulz-Zunkel and Krueger, 2009) and/or organic pollutants in major floodplains worldwide (Berger and Schwarzbauer, 2016;Zimmer et al, 20 2010;Lair et al, 2009). Most studies concerned with the Rhine focused on the industrializes Lower Rhine region including the Rhine-Meuse Delta (de Boer et al, 2010;Evers et al, 1988;Goth et al, 2001;Middelkoop, 2000).…”

Abstract. While the history of a fluvial hydrosystem can provide essential knowledge on present functioning, historical context remains rarely considered in river restoration. Here we show the relevance of an interdisciplinary study for improving 15 restoration within the framework of a European LIFE+ project on the French side of the Upper-Rhine (Rohrschollen Island).Planimetric evolution combined with historical high flow data enabled to reconstruct pre-disturbance hydromorphological functioning and major changes that occurred on the reach. A deposition frequency assessment combining vertical evolution of the Rhine thalweg, chronology of deposits in the floodplain and a hydrological model revealed that the period of vertical incision in the main channel corresponded to high rates of narrowing and lateral channel filling. The analysis of filling 20 processes by Passega diagram and IRLS dating highlight that periods of engineering works were closely related to fine sediment deposition, which present also concomitant heavy metal accumulation. In fact, current fluvial forms, processes and sediment chemistry around the Rohrschollen Island directly reflect the disturbances that occurred during past correction works, and up to today. Our results underscore the advantage of combining functional restoration with detailed knowledge of pasttrajectory to: (i) understand the functioning of the hydrosystem prior anthropogenic disturbances, (ii) characterize the human-25 driven morphodynamic adjustments during the two last centuries, (iii) characterize physio-chemical sediment properties to trace anthropogenic activities and evaluate the potential impact of the restoration on pollutant remobilization, (iv) deduce postrestoration evolution and (v) evaluate efficiency and sustainability of the restoration effects. We anticipate our approach to expand the toolbox of decision-makers and help orientating functional restoration actions in the future.
