“…Pore water total phosphorus is an important indicator of its release from sediments, which may be site specific (Thornton et al 2013) and must be monitored to calculate reasonable load estimates. Phosphate turnover and circulation may be influenced by hydrological dynamics, perhaps becoming the driving force, as reported for some Polish reservoirs (Trojanowska & Jezierski 2011). Seasonal and spatial phosphorus concentration variations in pore waters are significant, with their impacts on internal loading having been reported for another Polish lake, Swarz Edzkie (Kowalczewska-Madura & Goldyn 2011) and for Baiyangdian Lake in North China (Dong et al 2011). Internal phosphorus loading Nurnberg (1994) made the first attempt to classify lakes based on their anoxic sediment surfaces especially prone to high internal phosphorus loading.…”

This study examines sedimentation rate and its consequences on the bathymetry, capacity and internal phosphorus loading of Krishnagiri Reservoir in Tamil Nadu, South India, utilizing an acoustic Doppler profiler and remote sensing data in an ArcGIS environment. There was a significant change in the reservoir bathymetry for the year 2012, compared with the 2007. The sedimentation rate was 0.818 MCM from 1960 to 1990 and 0.83 MCM over past 5 years. The present reservoir volume is 35.57 MCM, having been reduced to nearly half of its original capacity over a 55 year span, pointing to a seriously threatened lifespan. The sediment total phosphorus (TP) load spatially varied from 6.84 to 23 394 kg, depending on the sediment deposition zones. Sequential extraction indicated the dominance of phosphate fractions to be Al‐P> Fe‐P> Ca‐P> SRP, with an average TP value of 27.27 mg g−1 dry weight. Aluminium‐ (35%) and iron(25%)‐bound forms are the major sediment phosphorus fractions, suggesting temperature, pH and redox or related chemical reactions may be important means of sediment P release in Krishnagiri Reservoir. The sediment phosphorus load in Krishnagiri Reservoir is estimated to be 44.50 tons, with an average TP release of 40.97 mg m−2 (range of 10.22–70 mg m−2). The measured pore water TP concentration and calculated sediment phosphate release exhibited a linear relation. Even with a reduced external P load, the eutrophication of Krishnagiri Reservoir cannot be reduced immediately because of its high internal load and nutrient remobilization.

“…The highest concentrations occurs mainly in the northern part of reservoir, which is also the deepest one. Al and Fe can affect incorporation and liberation of P from sediments, which is related to phosphorus retention in sediment and its realease into the water column [Trojanowska and Jezierski 2011]. It is the main reason why Al and Fe should be monitored along with the content of phosphorus.…”

The aim of this study was to determine the content of phosphorus and nitrogen in the bottom sediments of the Poraj Reservoir located on the Warta River, along with defining their spatial distribution and the relationship between these elements and organic matter, aluminum and iron. Samples of bottom sediments were collected on the basis of regular measurement grid of 46 points located in the area of the water reservoir Poraj. The collected samples were analyzed in terms of content of following elements, which values are in range: total phosphorus (TP) 0.06 -5.06 g/kg, total nitrogen (TN) 0.17 -9.66 g/kg, organic matter (OM) 0.49 -28.41% of solid content, aluminum (Al) 2.44 -145.15 g/kg and iron (Fe) 0.28 -16.50 g/kg. By using of GIS system, spatial distribution of obtained results of laboratory analyzes were interpolated (Inverse Distance Weighted method was used). On basis of spatial distribution it was noted that in northern part of water reservoir bottom sediments have greater values of TP, TN and OM than in southern part. The study also included calculation of correlation between: OM and TN (n=46, R 2 = 0.9335), TN and Fe (n=46, R 2 = 0.8782), TN and Al (n=46, R 2 = 0.8629), OM and Fe (n=46, R 2 = 0.8243), OM and Al (n=46, R 2 = 0.7981), TP and Fe (n=46, R 2 = 0.7456), TP and Al (n=46, R 2 = 0.6209). The presented pilot studies show that the potential content of phosphorus, nitrogen and organic matter in the sediments of the water reservoir Poraj can reach a significant level. The need to plan and carry out further research allowing the evaluation of the properties of the analyzed elements and examining their potential impact on water quality in the tested water reservoir was stated.

The specific of water management in the urbanized ares (regulation of watercourses, discharges of municipal and industrial effluents etc.) have resulted in the transformation of the natural drainage system of the basin of Kłodnica, in which Dzierżno Duże water reservoir is located. The main goal of this study was to designate the content of total phosphorus and total nitrogen, and relations between these elements and organic matter, level of depth, aluminum and iron in the bottom sediments of the Dzierżno Duże water reservoir. Bottom sediments samplings consisted of grid measurement network planning, on which bottom sediments samples were collected. The collected samples were analyzed in laboratory in terms of content of chosen elements. Values of these elements are in range: total phosphorus 0.08÷6.02 g/kg, total nitrogen 0.15÷9.03 g/kg, organic matter 0.20÷50.90% of solid content, aluminum 0.48÷39.32 g/kg and iron 0.82÷25.42 g/kg. To improve quality of performed analysis, by using Geographic Information System the spatial distributions (the Inverse Distance Method was used) of studied elements were generated. Generated spatial distributions enabled to determine sites with highest and lowest values. Bottom sediments of Dzierżno Duże water reservoir have greater values of total phosphorus, total nitrogen and organic matter in central regions than in coastal zone. The study also included calculation of correlation between: organic matter and total nitrogen (R 2 = 0.6), total nitrogen and Fe (R 2 = 0.44), total nitrogen and Al (R 2 = 0.5), organic matter and Fe (R 2 = 0.39), organic matter and Al (R 2 = 0.55), total phosphorus and Fe (R 2 = 0.57), total phosphorus and Al (R 2 = 0.56). The presented pilot studies may provide a basis for identifying harmful human activities and planning methods of counters measures. Dzierżno Duże water reservoir, among other functions, is a spot (mainly for local residents), therefore it should be monitored constantly.Keywords: bottom sediments, spatial distribution, biogenic substances Wprowadzenie Głównymi pierwiastkami biogennymi, które w znacznej mierze przyczyniają się do zwiększenia żyzności zbiorników wodnych i szybkiego postępu eutrofizacji, są azot i fosfor.
