“…Storage of fluvial sediments on inundated floodplains has been documented to constitute an important component of river basin sediment budgets (Mitsch et al, 1979; Kuenzler et al, 1980; Johnston et al, 1984; Cooper et al, 1987; He and Walling, 1997; Walling, 1999; Kronvang et al, 2002; Sweet et al, 2003; Owens and Walling, 2003; Walling and Owens, 2003). The evidence of deposition of P on inundated riparian floodplains is not as widely documented, but the existing results demonstrate that sedimentation is an important mechanism in riparian floodplains (Table 7).…”

Phosphorus Retention in Riparian Buffers: Review of Their Efficiency

Ground water and surface water interactions are of fundamental importance for the biogeochemical processes governing phosphorus (P) dynamics in riparian buffers. The four most important conceptual hydrological pathways for P losses from and P retention in riparian buffers are reviewed in this paper: (i) The diffuse flow path with ground water flow through the riparian aquifer, (ii) the overland flow path across the riparian buffer with water coming from adjacent agricultural fields, (iii) irrigation of the riparian buffer with tile drainage water from agricultural fields where disconnected tile drains irrigate the riparian buffer, and (iv) inundation of the riparian buffer (floodplain) with river water during short or longer periods. We have examined how the different flow paths in the riparian buffer influence P retention mechanisms theoretically and from empirical evidence. The different hydrological flow paths determine where and how water-borne P compounds meet and interact with iron and aluminum oxides or other minerals in the geochemical cycling of P in the complex and dynamic environment that constitutes a riparian buffer. The main physical process in the riparian buffer-sedimentation-is active along several flow paths and may account for P retention rates of up to 128 kg P ha(-1) yr(-1), while plant uptake may temporarily immobilize up to 15 kg P ha(-1) yr(-1). Retention of dissolved P in riparian buffers is not as pronounced as retention of particulate P and is often below 0.5 kg P ha(-1) yr(-1). Several studies show significant release of dissolved P (i.e., up to 8 kg P ha(-1) yr(-1)).

“…The most detailed and, at the same time, spatially distributed investigations of the river floodplain overbank sedimentation for the last 50–100 years have been undertaken by D.E. Walling with colleagues in the UK over the last two decades (Walling and Bradley, ; Walling and He, , ; Walling et al ., , , ; Owens and Walling, , ; Du and Walling, ). Nevertheless, information on downstream variation of floodplain sedimentation rates along a particular river is rarely available.…”

Floodplain sedimentation is one of the most dynamic geomorphic processes within plain and lowland landscapes. There is generally a good understanding of longer term floodplain evolution, but quantitative information on overbank deposition rates for recent shorter timescales is lacking. This paper describes the application of Chernobyl-derived 137 Cs to quantify floodplain aggradation rates for the River Plava (a small river draining a severely contaminated part of the upland region of Central European Russia), based on detailed sampling of four representative floodplain study sites. Two approaches have been employed for estimating post-Chernobyl (1986-2009) floodplain accumulation rates. The first was based simply on locating the Chernobyl fallout-associated 137 Cs peak in overbank sediment sections. The second involved quantification of the increase in the total 137 Cs inventory at individual sampling points associated with the post-Chernobyl deposition of contaminated suspended sediment. It has been shown that considerable local-scale variability of overbank deposition rates exists, with aggradation rates on the low level floodplain (6 AE 1.2-14 AE 2.8 mm year À1 ) exceeding by 1.5-3 times the values for the middle level floodplain (2 AE 0.4-9 AE 1.8 mm year À1 ) and by 3-6 times the values for the upper level floodplain (1 AE 0.2-5 AE 1.0 mm year À1 ) floodplain levels. Combining these estimates with information on the areas occupied by different floodplain levels within the 54 km long valley section, derived from detailed geomorphic surveys of the selected reaches, it has been estimated that about 9700 AE 1950 t of sediment have been stored on floodplain during the 1986-2009 period. The role of floodplain storage in the overall basin sediment budget and conveyance losses within the main channel system have been evaluated. a First figure -assuming maximum rate of downward migration for the 1986 peak, second figure -assuming minimum rate of downward migration for the 1986 peak. 816 V.

“…Moreover, metal redistribution in vertical profiles, which reflects to some extent metal transfer from sediments to surface waters, is also related to changes in redox conditions and precipitation with Fe hydroxides (Cappuyns and Swennen 2004;Kraus and Wiegand 2006). Investigations of metal mine-contaminated catchments indicate the role of channel and floodplain sediments as an important diffuse metal source (Owens and Walling 2003;Mighanetara et al 2009). This should be recognised in the context of their spatial variability and the rate of post-depositional metal migration, so as to formulate management and site remediation strategies (Hudson-Edwards et al 1998).…”

Purpose The Matylda catchment, in southern Poland, was polluted by the discharge of mine waters from a lead and zinc mine that inundated parts of a valley floor and caused the accumulation of metal-polluted sediments. After a partial reclamation of the mine site in the early 1980s, polluted sediments continue to accumulate on downstream floodplains and in fishponds. The aim of this study was to reconstruct the changes in metal dispersal during 100 years of mining and during the 40-year post-mining period and to propose a strategy for pollution mitigation in the area. Materials and methods Analyses of Cu, Cd, Pb, Zn, Mn, Ca, Mg and Fe concentrations, speciation of heavy metals and mineralogical analyses were undertaken on overbank sediment cores and in stream sediments. Concentrations of the same elements and macro-ions soluble in stream waters were also determined. Results and discussion Concentrations of Zn, Cd and Pb in the sediment profiles vary between 40,000 and 55,000, 300 and 600 and 30,000 and 50,000 mg kg -1 , respectively. Changes of metal concentrations and the stratigraphy of sediments from the floodplains, stream channels and fishponds suggest rapid changes of metal loads migrating downstream during both the mining and post-mining periods. Since the time of mine closure, fine-grained, mine-derived sediments (ca. 12 cm thick) have been the main source of pollution of post-mining sediments and surface waters. Closure of the mine was followed by a relatively short period of rapid redistribution of sediment-associated heavy metals in the stream channel. Since the 1980s, the floodplain and fishponds have received a constant supply of metals. It contrasts with the slow sediment accretion rate and a rapid decrease of metal concentrations in floodplain pools due to dilution by decomposed leaf litter. A fivefold increase of Cd content in waters over the 4.6 km reach of the Matylda stream indicates continuous leaching of this element from the contaminated valley floor. Conclusions Unsuccessful mine site rehabilitation is due to leaching of mine-originated sediments dispersed over the valley bottom. However, the rate of metal remobilization over the last 40 years is low because of the small thickness and widespread anoxic conditions that prevail within both recent and mine-originated sediments and the alkaline pH of stream water, which reduces metal mobility. Distribution of the contaminated layer over a large area of the valley bottom precludes cost-efficient catchment rehabilitation.
