“…In 1995-2008 the nutrient load calculated on the monitoring basis was lower (13% for the Vistula River and 19% for the Oder River) than calculated with the MONERIS model [PASTUSZAK, IGRAS 2012]. The MONERIS research hypothesis argues that drainage and ground waters discharge part of the excess of nitrogen from the soil calculated according to OECD, which in the drainage basin of the Weser would be equivalent to a high area specific load of 13.4 kg N·ha [KREINS et al 2010], whereas groundwater and drainage water runoff amounted to as much as 72.3% N and 41.6% P respectively.…”

The research methodology for determining the sources of nutrients responsible for the eutrophication of rivers and seas, as well as the extent of their load in particular drainage basins, has for many years been at the centre of vigorous discussion. In the Oder and Vistula river basin, apart from the calculation of monthly and annual loads of nitrogen and phosphorus, based on the discharge and chemical monitoring data of waters, the MONERIS (Modeling Nutrient Emissions in River Systems) model has also been applied in determining nutrient sources. This article, on the basis of a comprehensive review of the professional literature, shall cast a critical eye over six issues that have been at the centre of past robust discussion: 1) determining the balance of N and P in agriculture, 2) the effects of a significant improvement in sewage treatment, 3) impact of technology on agriculture, 4) determination of nutrient retention in drainage basins, 5) impact of tile drainage practices on the leaching of nutrients, 6) as well as the accuracy of calculations made according to the MONERIS model. It would appear that for practical purposes it is sufficient to determine given loads of N and P from the drainage basins of particular rivers, as well as to adjust the above mentioned model, or indeed -resign from the unproven methodology of determining nutrient sources in rivers.

“…70% of nitrogen emission was via groundwater and tile drainage. The contribution of the tile drained area in the Oder River Basin was much higher (48% N, 8% P) than in the Vistula River Basin (29% N, 4% P) [KOWALKOWSKI et al 2012].…”

“…In addition, this analysis shows that the mean nutrient concentrations in some of the gauges were significantly greater in 2000-2005 than in 2006-2011. The first decade of the twentieth century in Poland has been marked by rapid development in the number of sewage treatment plants and by an increasing treatment level [60]. Because the majority of the input data used to build the model setup were valid for 2010 or later and may represent the period of 2000-2005, we hypothesized that this finding could partially explain the poor model performance during validation.…”

The objective of this paper was to spatially quantify diffuse pollution sources and estimate the potential efficiency of applying riparian buffer zones as a conservation practice for mitigating chemical pollutant losses. This study was conducted using a semi-distributed Soil and Water Assessment Tool (SWAT) model that underwent extensive calibration and validation in the Sulejów Reservoir catchment (SRC), which occupies 4900 km 2 in central Poland. The model was calibrated and validated against daily discharges (10 gauges), NO 3 -N and TP loads (7 gauges). Overall, the model generally performed well during the calibration period but not during the validation period for simulating discharge and loading of NO 3 -N and TP. Diffuse agricultural sources appeared to be the main contributors to the elevated NO 3 -N and TP loads in the streams. The existing, default representation of buffer zones in SWAT uses a VFS sub-model that only affects the contaminants present in surface runoff.Water 2015, 7 1890The results of an extensive monitoring program carried out in 2011-2013 in the SRC suggest that buffer zones are highly efficient for reducing NO 3 -N and TP concentrations in shallow groundwater. On average, reductions of 56% and 76% were observed, respectively. An improved simulation of buffer zones in SWAT was achieved through empirical upscaling of the measurement results. The mean values of the sub-basin level reductions are 0.16 kg NO 3 /ha (5.9%) and 0.03 kg TP/ha (19.4%). The buffer zones simulated using this approach contributed 24% for NO 3 -N and 54% for TP to the total achieved mean reduction at the sub-basin level. This result suggests that additional measures are needed to achieve acceptable water quality status in all water bodies of the SRC, despite the fact that the buffer zones have a high potential for reducing contaminant emissions.

“…In the latter half of the 20 th century the Vistula River was heavily polluted, However increased sewage plant capacity, which reduced the organic pollution, resulted in the 1990s in the gradual improvement of water quality which was recorded in research carried out since 1986 (Kentzer 2009;Pastuszek et al 2012;Kowalkowski et al 2012). In most cases (Mieszczankin 2009), the values of physical and chemical water parameters (T, pH, O 2 , BOD 5 , N-NH 4 , Cond., Salinity, P-PO 4 , TP and Chl-a) correspond to I class and rarely to II class by ecological state of water quality in accordance with the requirements for surface flowing waters (DzU 2008) of Poland.…”

The diversity and longitudinal variation of zooplankton in the lower Vistula River were analyzed. Samples were taken from 40 stations located along a 272-km long section of the lower river course. During the study the unique technique of taking samples from "the same water" was used. The zooplankton community was dominated by rotifers and naupliilarval stages of copepods. The most abundant species were: Brachionus angularis, Brachionus calyciflorus and Brachionus budapestiensis. The zooplankton species diversity in the main channel of the lower Vistula River was similar to other large European rivers; however, its abundance was lower. The diversity, abundance and biomass of potamoplankton steadily decreased downstream. This could be related both to scarcity of storage zones for potamoplankton development in the river due to the extensive regulation processes, and changes in hydrological conditions of the main channel (by the straightening of riverbed) where the samples were collected.
