“…As for the effect of the floodplain period on dissolved oxygen, the average value before the flood was 7.7-9 mg/L ( 74.28-93.26 %), whereas it was 7.7-11.4 mg /L (89.78-115.6 %) during the floodplain period, and 7-10 mg /L (90.9-132.1%) and after the floodplain period ( Table-3). This may be due to the fact that the nutrients that are transferred with floodplain water can promote the growth of algae and water plants, which are responsible for producing oxygen in water [45].…”

The current study was conducted on the southern part of Gharaf River in order to define the physical-chemical properties and the impact of the Tigris River’s floodplain water on its ecological characteristics during 2019. Four sites were selected along the southern part of the river. The findings showed a strong connection between the temperature of air and water at all sites. A value ranging from 4.85 - 84.65 NTU was reported for turbidity. The water was found to be oligohaline, low alkaline, and well ventilated due to high dissolved oxygen concentrations. Gharaf River is considered to be of questionable clean water, according to the results of BOD5. The total alkalinity values were recorded to be in the range of 92-292.8 mg /L, which are higher than the acceptable limits of 20-200 mg /L CaCO3 for the Iraqi and international water standards. It was also found that Gharaf River water was very hard, but still within the allowable natural water limits (200 mg /L Ca and 150 mg /L Mg). Concentrations of sulphate ranged 50-200 mg / L, while levels of bicarbonate ranged 140-230 mg /L. On the other hand, ranges of 3354-855 mg / L and 3-85 mg / L, respectively, were recorded for TDS and TSS. In addition, nitrates values were found to be in the range of 0.04-5.14 mg / L, being below the permissible limits for Iraqi water (15 mg / L). Other values observed for phosphates were 0.004-0.085 mg / L. Overall, the results demonstrated different effects on the properties of Gharaf River water during and after the floodplain period.

“…Together with the collection of zooplankton samples, physical and chemical parameters of water were studied, such as pH, conductivity (EC), total phosphorus (TP), mineral nitrogen (N min ), organic nitrogen (N org ), particulate matter (PM), organic matter (OM) and chlorophyll a. The physical and chemical methodology was described by Golterman (1971), Greenberg et al (1992), Mieszczankin (2000), Mieszczankin (2009) and Operacz et al (2011).…”

The aim of the study was to determine changes in potamoplankton structure caused by lakes in the fluvial system of the small River Wel. The river flows through 10 lakes. The study was conducted in 2007 and 2008. The selection of sites enabled the assessment of the impact exerted by hydrological conditions of the river on zooplankton, as well as the determination of the effect of lakes situated within the river course on the analysed assemblage of organisms. In total 95 species were determined with an average abundance 1026 ind. 10 dm-3. Rotifers dominated qualitatively and quantitatively and among crustaceans - Copepods. Lakes seem to be the main source of zooplankton in the fluvial system of the Wel River. The lakes disturb the river continuum, but their impact on the structure of zooplankton is short-lived. Due to the presence of flow-through lakes along the river, species richness of zooplankton in the Wel River is similar to that in large rivers.

“…At the studied part of the river there were no significant inflows of the other rivers. The effluents fed to the river were sufficiently treated so that they did not change the quality of the water in main channel of the river (Mieszczankin 2009). According to RCC and assumed that hydrological condition change slowly along the Vistula River (G logowska 2000) we decided to turn our attention to the hydrological conditions and their influence on zooplankton.…”

“…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. However, the lower Vistula River, as moderately eutrophic river (Table 5), still could provides the advantageous conditions for a distinct longitudinal zooplankton development.…”

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.
