“…In the profundal zone, where clayey sediments dominate, assimilation of heavy metals in finer deposits is generally higher than in sandy sediments [43]. The texture of the bottom sediments in the Ninjing River and Lake Taihu, which is supplied by that river, was correlated with heavy metal concentrations (mostly with the clay fraction and the sand fraction) [44]. The bottom sediments of the lake were moderately contaminated, mostly with Pb and Ni, but the noted heavy metal concentrations did not pose a threat to living organisms, although toxic effects on aquatic organisms is already observed at a concentration of 0.1 ppm [45].…”

River-lake systems most often behave as hydrographic units, which undergo complex interactions, especially in the contact zone. One such interaction pertains to the role of a river in the dispersal of trace elements carried into and out of a lake. In this study, we aimed to assess the impact of rivers on the accumulation of heavy metals in bottom sediments of natural lakes comprised in postglacial river-lake systems. The results showed that a river flowing through a lake is a key factor responsible for the input of the majority of available fraction of heavy metals (Zn, Mn, Cd and Ni) into the water body and for their accumulation along the flow of river water in the lake. The origin of other accumulated elements were the linear and point sources in catchments. In turn, the Pb content was associated with the location of roads in the direct catchment, while the sediment structure (especially size of fraction and density) could have affected the accumulation of Cr and Zn, which indicated correlations between these metals and fine fraction. Our results suggest that lakes act as filters and contribute to the self-purification of water that flows through them. As a result, the content of most metals in lake sediments showed a decrease by approx. 75% between the upstream (inflow) and downstream (outflow) sections. The increased content of two metals only, such as chromium and cadmium (higher by 2.0 and 2.5 times, respectively, after passing through the lake), was due to the correlation of the metals with fine sand. Both the content and distribution pattern of heavy metals in lake sediments are indicative of the natural response of aquatic ecosystems to environmental stressors, such as pollutant import with river water or climate change. The complex elements creating the water ecosystem of each lake can counteract stress by temporarily removing pollutants such as toxic metals form circulation and depositing them mostly around the delta.

“…In very dry sediments, smallscale variability of moisture content tends to be the lowest; it increases gradually with the amount of moisture, but it starts to drop and reaches the lowest values in very wet sediments (Edwards, 2013). Previous studies reported spatial variability with respect to both organic matter (Szczuciński et al, 2013;Yuan et al, 2014) and pH (Diab et al, 2014;Yuan et al, 2014) for sediments along the deposition areas.…”

IntroductionSediment is described as solid particles generated by the disintegration process of organic and inorganic materials (Bortone, 2006). These particles, found in various shapes and sizes, can be transported by water, wind, glaciers, and other natural causes (Montgomery et al., 2000). Sediment deposited in deltas and reservoirs are generally fine-grained (sand, silt, and clay) (Kamarudin et al., 2009;Tigrek and Aras, 2011). The sedimentation process depends on the flow regime and flow rate of the river (Kamarudin et al., 2009). Natural rivers are considered balanced with respect to sediment and water inflow and outflow. However, when rivers are controlled, especially by the construction of large dams, this balance can be dramatically changed (Morris and Fan, 1998). The alteration of the natural flow regime leads to changes to the hydrological, geomorphological, and ecological conditions both upstream and downstream (Galay, 1983;Graf, 2006;Magilligan et al., 2013;Csiki and Rhoads, 2014;. Dam construction in rivers decreases velocity, causing a sedimentation increase upstream of the dam. This reduces the storage capacity of reservoirs, thus negatively influencing other benefits of large dams, such as water supply, power production, and flood control (Morris and Fan, 1998). Sedimentation can change geomorphological conditions upstream of reservoir areas. For example, sediments deposited along riverbanks due to reduced flow will narrow the cross-section of a river before it reaches the reservoir, while the accumulated sediments can change the terrain of the bottom of the reservoir (Ryan, 1991;Csiki and Rhoads, 2014). Changes in the amount and composition of sediment, carrying

“…Principal component analysis (PCA) and correlation test (CT) have been conducted by researchers worldwide to make groundwater management decisions [43][44][45][46]. For instance, Guo [44] used PCA to identify the relationship among heavy metals of flood slack water deposits and their possible sources; and Zhang [46] used PCA to determine factors that influence the composition of groundwater.…”

Water shortage is severe in the North China Plain (NCP). In addition to a deficiency of water resources, deterioration of groundwater quality should be of great concern. In this study, hydrogeological analysis was conducted in combination with principal component analysis, correlation analysis and the co-kriging method to identify factors controlling the content of major ions and total dissolved solids (TDS) in areal shallow and deep groundwater and to assess groundwater evolution in Cangzhou, China. The results suggested that groundwater quality degradation occurred and developed in the study area, as indicated by increasing concentrations of major ions, TDS and hardness in both shallow and deep groundwater. In shallow groundwater, whose hydrochemical water types changed from HCO3-Ca.Na.Mg and HCO3.Cl-Na in the west (Zone II) to Cl.SO4-Na and Cl-Na in the east (Zone III). Areas with TDS concentrations between 1500 and 2000 mg/L occupied 79.76% of the total in the 1980s, while areas with a TDS concentration ranging from 2500 to 3000 mg/L comprised 59.11% of the total in the 2010s. In deep groundwater, the area with TDS over 1000 mg/L expanded from 5366.39 km groundwater. Dissolution of dolomite, calcite, feldspar and gypsum were the primary sources of major ions in groundwater, and the ion exchange reaction had a strong effect on the cation content, especially for deep groundwater.
