“…However, high level of Cu in the sediment could be potentially toxic and this may pose concern because of bioaccumulation once in the food chain. The high level of Cu found in the sediment could be due to both natural origins and man-induced activities which are widely reported in the literature (Christensen and Juracek, 2001 (2009), who recorded the Pb concentration of 35 ± 16.17 ìg/g dry weights. Compared to our study, there is a slight reduction in the Pb concentration in Kuah station was apparent during 2009 though it is not statistically significant (p > 0.05).…”

The coastal zone is an important area as it affects the global environments through the interaction between land and ocean (Kremer et al., 2005). Metal concentrations in sediments usually exceed those of the overlying water column (Caroline et al., 2002). As a consequence, metals originating from human activities can often be identified more readily by analysis of sediment than by the quantification of metal concentrations present in water (Haynes et al., 2006). Kevin et al., (2006) has reported the ability of the sediments in integrating the temporal variability of metals that are originating from human sources. He also

“…Individual sites are ''strongly'' or ''excessively contaminated'' with Cd and generally ''moderately/strongly contaminated'' with Zn, Pb, and Cu. The maximum Cd, Pb, and Zn values frequently exceed the ''Probable Effect Level'' (PEL), defined by the U.S. Environmental Protection Agency (EPA) as the level above which metals have the potential to produce toxic biological effects (Christensen and Juracek, 2001).…”

“…Vibracoring is a common approach for obtaining undisturbed cores of unconsolidated sediment in saturated or nearly saturated conditions (Lanesky et al, 1979;Smith, 1984). Gravity corers also have been successfully used to obtain sediment cores within reservoirs (Van Metre et al, 1997, 1998Callender and Rice, 2000;Christensen and Juracek, 2001). This system, which costs approximately $15,000, uses a 1-HP motor that drives a pair of weights (masses) eccentrically mounted on two shafts, and it is housed within a watertight aluminum chamber so it can be immersed in water.…”

Since the dam was constructed in 1955 and the first 137Cs was observed in 1954 ± 2, the sand and gravel layers located stratigraphically below the silt and clay layers with depleted concentrations of 137Cs are interpreted as parent (preconstruction) et al (1997, 1998) and Christensen and Juracek (2001) also utilized 137Cs to determine stratigraphic timelines and uncorrected linear sedimentation rates within reservoirs.…”

The Challenges of Dam Removal and River Restoration

Flood-control reservoirs designed and built by federal agencies have been extremely effective in reducing the ravages of floods nationwide. Yet some structures are being removed for a variety of reasons, while others are aging rapidly and require either rehabilitation or decommissioning. The focus of the paper is to summarize collaborative research activities to assess sedimentation issues within aging flood-control reservoirs and to provide guidance on such tools and technologies. Ten flood-control reservoirs located in Oklahoma, Mississippi, and Wisconsin have been examined using vibracoring, stratigraphic, geochronologic, geophysical, chemical, and geochemical techniques and analyses. These techniques and analyses facilitated: (1) the demarcation of the pre-reservoir sediment horizon within the deposited reservoir sediment, (2) definition of the textural and stratigraphic characteristics of the sediment over time and space, (3) the accurate determination of the remaining reservoir storage capacity, (4) the quantification of sediment quality with respect to agrichemicals and environmentally important trace elements over both time and space, and (5) the determination of geochemical conditions within the deposited sediment and the potential mobility of associated elements. The techniques employed and discussed here have proven to be successful in the assessment of sediment deposited within aging flood-control reservoirs, and it is envisioned that these same approaches could be adopted by federal agencies as part of their national reservoir management programs.
