“…The elevated Ti values (Fig. 5) indicate high erosional input ) most likely from the river floodplain and runoff from the surrounding agricultural catchment, causing the rapid infilling (Hudson et al 2008) of the lake basin with exceptionally high sedimentation rates of *2.3 cm year -1 . In addition to the high sedimentation rates, the lake exhibits fluctuating diatom concentrations and abrupt changes in the dominant hypertrophic diatom taxa (Fig.…”

“…Lake De Waay is situated to the east of the Diefdijk, a secondary dike that prevents flooding of agricultural land in westerly polders and that prevents drainage of the easterly polder Tielerwaard. In the past this repeatedly resulted in prolonged flooding of the Tielerwaard polder and Lake De Waay after river dike breaches (Middelkoop 1997;van Hemmen et al 2007;Hudson et al 2008). The lake itself was formed in the fifteenth century by a dike breach of the Diefdijk, likely as a result of damage by floating ice in winter (van Hemmen et al 2007).…”

“…In the Middle Ages a new type of lake was formed due to dike breaches caused by high floods of the river Rhine. These dike-breach lakes have been strongly regulated by the development of a channel system and agriculture (Berendsen and Stouthamer 2001;Hudson et al 2008). Despite several sedimentological, hydrological, and biological observations in the delta region (Lammens et al 2008), the flooding history and ecology of these floodplain lakes have rarely been studied.…”

500 years of trophic-state history of a hypertrophic Dutch dike-breach lake

We present a palaeolimnological study encompassing five centuries of trophic-state change of the dike-breach lake De Waay located on the RhineMeuse delta (the Netherlands). Diatom-inferred total phosphorus (TP) concentrations indicate hypertrophic epilimnetic conditions ([300 lg l -1 TP) since the formation of the lake in the fifteenth century until the end of the eighteenth century. Cladocera data support the reconstructed trophic state and indicate turbid conditions in lake De Waay during this period. High inferred TP concentrations as well as the amount of Ti in the sediment reflect numerous flooding events. From the nineteenth century onwards reconstructed TP concentrations decreased to 40-150 lg l -1 due to improvements in sewage and dike systems that considerably diminished direct river flooding and seepage-derived nutrients. As a consequence, the increased stability of littoral habitats led to an increased diversity of the Cladocera assemblages.The most significant decrease in TP concentrations to *40 lg l -1 occurred between about 1900 and 1930. This mesotrophic phase was a consequence of the isolation of the lake from catchment drainage and the introduction of a highly elaborate flood control during this period. However, since the mid twentieth century a eutrophication trend is preserved in the record, likely related to increased agricultural activity in the vicinity of the lake. Our results emphasize that landuse and trophic-state history must be taken into account when evaluating the ecological status of lakes for water management and protection actions, especially for lakes in landscapes that are strongly modified by human action.

Abstract:Before 1900, the Missouri-Mississippi River system transported an estimated 400 million metric tons per year of sediment from the interior of the United States to coastal Louisiana. During the last two decades (1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006), this transport has averaged 145 million metric tons per year. The cause for this substantial decrease in sediment has been attributed to the trapping characteristics of dams constructed on the muddy part of the Missouri River during the 1950s. However, reexamination of more than 60 years of water-and sediment-discharge data indicates that the dams alone are not the sole cause. These dams trap about 100-150 million metric tons per year, which represent about half the decrease in sediment discharge near the mouth of the Mississippi. Changes in relations between water discharge and suspended-sediment concentration suggest that the Missouri-Mississippi has been transformed from a transport-limited to a supply-limited system. Thus, other engineering activities such as meander cutoffs, river-training structures, and bank revetments as well as soil erosion controls have trapped sediment, eliminated sediment sources, or protected sediment that was once available for transport episodically throughout the year. Removing major engineering structures such as dams probably would not restore sediment discharges to pre-1900 state, mainly because of the numerous smaller engineering structures and other soil-retention works throughout the Missouri-Mississippi system.

“…Although these structures successfully reduce flood risks, they disrupt morphodynamic processes and ecological functioning of the system and involve high costs for construction and maintenance (Hudson et al 2008). Therefore, it is now often considered to shift the management to soft engineering measures that aim at a more natural and multifunctional system where dynamic hydrological, morphological, and ecological processes are restored.…”

Factors controlling sediment trapping in two freshwater tidal wetlands in the Biesbosch area, The Netherlands

Purpose A thorough understanding of mechanisms controlling sedimentation and erosion is vital for a proper assessment of the effectiveness of delta restoration. Only few field-based studies have been undertaken in freshwater tidal wetlands. Furthermore, studies that measured sediment deposition in newly created wetlands are also sparse. This paper aims to identify the factors controlling the sediment trapping of two newly created freshwater tidal wetlands. Materials and methods Two recently re-opened polder areas in the Biesbosch, The Netherlands are used as study area. Field measurements of water levels, flow velocities, and turbidity at both the in-and outlet of the areas were carried out to determine the sediment budgets and trapping efficiencies under varying conditions of river discharge, tide, and wind in the period 2014-2016. Results and discussion Short-term sediment fluxes of the two study areas varied due to river discharge, tide, and wind. A positive sediment budget and trapping efficiency was found for the first study area, which has a continuing supply of river water and sediment. Sediment was lost from the second study area which lies further from the river and had a lower sediment supply. The daily sediment budget is positively related to upstream river discharge, and in general, export takes place during ebb and import during flood. However, strong wind events overrule this pattern, and trapping efficiencies decrease for increasing wind strengths at mid-range river discharges and for the highest river discharges due to increased shear stress. Conclusions Delta restoration, based on sedimentation to compensate for sea-level rise and soil subsidence, could only be effective when there is a sufficient supply of water and sediment. Management to enhance the trapping efficiency of the incoming sediment should focus on directing sufficient river flow into the wetland, ensuring the supply of water and sediment within the system during a tidal cycle, creating sufficiently large residence time of water within the polder areas for sediment settling, and decreasing wave shear stress by the establishment of vegetation or topographic irregularities.
