The influence of macrogeographical on hydrochemical data for cherek reservoir

The paper considers the influence of individual formations of macrogeographical in the period of their vegetation to some hydrochemical data for Cherek reservoir. The main plant species affecting the hydrochemical parameters of reservoir macrophytes: reed (Phragmites communis), narrowleaved cattail (Typha august folia), Soucek umbrella (Butomus umbelatus), floating pondweed (Potamogeton natans). Identified three group formation: air-water, floating, and submerged vegetation. Our research shows, that some formations have a significant influence on the hydrochemical composition of the Cherek reservoir. The pH value in the daytime (the period of maximum photosynthesis) in the estuaries of rivers, in the southern and the Northern part is higher than in the open part of the reservoir. The high values observed in the southern part, where is a large number of developed Susak umbrella. A consequence of changes in pH in the direction of its increase in certain conditions promotes the formation of carbonate, calcium and its deposition on the surface of plants. The least concentration of calcium observed in the Northern zone, where the variability was 10.9-12,2 mg/l. Diurnal variation of dissolved oxygen concentration was different. In the southern zone in the daytime maximum (6,89-6, 93 mg/l). In the open part of the reservoir these parameters were minimal (6,42-4,75 mg/l). The level of individual ingredients largely depends on the location of the sampling sites and the availability of vegetation and its species composition the number of sulfate ions ranges from 10 to 37, bicarbonates from 139 to 206,8 mg/l. are particularly large fluctuations in the content of trace elements, iron, copper, zinc, manganese.
