“…Moreover, higher water levels in May reduced the ability of wind to disturb sediment surface. Thus, the results of the present study, which revealed a mainly increasing effect of wind on TP values in a period after the 180 th Julian day, and reducing influences in the preceding period, are in close agreement with the results obtained from a sediment-trap field survey (Tammeorg et al, 2013). Therefore, the results of the present study suggest severe implications of climate change on the lake ecosystems such as an increase of internal phosphorus loading, since a higher frequency of extreme wind events can be expected in the future (Jeppesen et al, 2009 …”

“…In a recent study on sediment resuspension in large shallow waters of Lake Peipsi, wind was identified to be the main driving force behind the variations in sediment resuspension (Tammeorg et al, 2013). The effect of wind was found to be particularly pronounced at lower water levels in September, when the highest rates of sediment resuspension, and when the highest concentrations of suspended solids, TP, and Chl a were measured.…”

“…Bottom sediments play an important role in the accumulation of nutrients (Kowalczewska-Madura et al 2010). Nitrogen and phosphorus compounds accumulated in sediments can be released as a result of water overturn caused by wind waves (de Vicente et al 2009, Tammeorg et al 2013 as well as by human activity. Yousef et al (1980) proved that mixing of water above sediments and disturbances in their structure induced by cabin cruisers sailing on shallow lakes (average depth 1.8 -4 m) increased the release of orthophosphates from bottom sediments and their concentration was by 16 -73% higher.…”

This study presents the directions and the rate of changes occurring in the coastal lakes Jamno and Bukowo, located in northern Poland. Based on the cartographic materials and aerial photographs of those water bodies, it was established that in 1909-2012, the area of the lakes decreased by 183.6 ha (7.7%) and 250.7 ha (13.6%) for Jamno and Bukowo, respectively. Another component of lake disappearance − shallowing of lake basins − was analyzed using bathymetric plans. It turned out that water supplies of Jamno during more than 100 years decreased by 2.4 million m 3 (5.9%), while in the case of Bukowo, it was 5.9 million (17.5%). Unfavorable location (inflow of pollutants from the basin) and morphometry of both lakes should be considered as the main causes of such major changes. The lakes are polymictic with a considerable area of the shallowest zone (1 m depth). This favors the vegetation succession and, consequently, shallowing of the lake basins. Moreover, direct connection with the Baltic Sea contributes to the fact that the materials of marine * Corresponding author: Agnieszka-Strzelczak@zut.edu.pl origin deposited in the form of a reverse delta also contribute to a decrease in the open water surface area.

“…Sediment resuspension is an important process for oxygen and nutrient dynamics in aquatic ecosystems (Schallenberg and Burns, 2004;You et al, 2007b;Tammeorg et al, 2013). Tubificid worms and other benthic animals also significantly influence the oxygen and nutrient dynamics in the water, sediment and across the sediment-water interface (Lewandowski and Hupfer, 2005;Mermillod-Blondin et al, 2005;Zhang et al, 2010).…”

“…The increase of particles in the water column causes light attenuation and decreases the water transparency (James et al, 2004;Sorokina and Kulygin, 2013). Accompanying sediment resuspension are an enhanced exchange between the porewater and overlying water and the adsorption and desorption of resuspended particles, factors that influence phosphorus and nitrogen cycling across the sediment-water interface (You et al, 2007b;de Vicente et al, 2010;Kalnejais et al, 2010;Couceiro et al, 2013;Tammeorg et al, 2013). Consequently, the plankton and ecological structure in aquatic ecosystems are also changed (Schallenberg and Burns, 2004;Song et al, 2010;Kang et al, 2013).…”

-Sediment resuspension is an important internal lake process in regulating nutrient cycling and ecosystem structure. Tubificid worms are widely and abundantly distributed in freshwater ecosystems and are able to alter the sediment characteristics. This study was conducted to verify the hypothesis that the alteration of sediments by tubificids may substantially influence the sediment resuspension process. Specifically, we investigated the influence of Limnodrilus hoffmeisteri (Tubificidae) on sediment resuspension using an apparatus designed to simulate the sediment resuspension process in Lake Taihu (China). We examined L. hoffmeisteri according to its density (30 000 ind.m x2 ) in Lake Taihu and simulated the light ) wind processes present in Lake Taihu. Tubificids loosened the sediment through their feeding and defecation activities and increased the sediment water content. The appearance of tubificids increased the suspended solids (SS) in a 1.6 m water column under all three wind processes. During the sedimentation process, SS decreased rapidly in both the control and tubificid treatments. The total SS in the water column was significantly increased by tubificids and it changed significantly with time. In addition, the small size particles of the SS in the tubificid treatment were higher than that in the control. So, the appearance of tubificid worms (L. hoffmeisteri) enhanced sediment resuspension and raised the proportion of small size particles in SS.
