The dynamics of anthropogenic activity and anthropogenic sources of nutrients in the Republic of Bashkortostan have been analyzed. Statistical analysis of many-year data of hydrochemical monitoring have been used to establish the year-to-year and annual regularities in the variations of N compound concentrations in watercourses. Maps of the mean annual N concentration in its forms (ammonium, nitrites, and nitrates) have been constructed. The fitness of river water to different types of water use have been assessed. Probability distributions of the concentrations of hydrochemical components have been constructed for different phases of stream water regimes. The exceedance probabilities have been evaluated for MAC values of N compounds in watercourses. 相似文献

The semi-distributed physically-based model ECOMAG-HM was developed to simulate cycling of heavy metals in large river basins: on the surface, and in soil, groundwater and river water. The model was applied to study the spatial distribution and temporal dynamics of copper concentrations in watercourses of the Nizhnekamskoe Reservoir watershed in Russia. This watershed is characterized by high background concentrations of heavy metals due to wide occurrence of ore deposits and considerable concentrations of ore-parent elements in rocks. The model was found to adequately reproduce the spatial variation of the mean annual copper concentrations at different monitoring points of the river network. The mean annual specific copper washoff, with the surface and subsurface components of river runoff, and the total copper washoff from the watershed into the river network were calculated and mapped. The contributions of natural and anthropogenic factors to river water pollution by copper were evaluated. 相似文献

Spatiotemporal regularities of changes in mean annual air temperature and annual precipitation amount values for the Belaya
River basin were revealed on the basis of the analysis of statistical homogeneity of their long-term series. It is established
that warming has occurred by now and the increase in precipitation amount is registered in the Belaya River basin. Revealed
was the contribution of mean seasonal air temperature and precipitation changes to the changes in their mean long-term values. 相似文献

The decomposition of water quality formation of city watercourse was carried out. The ratio of natural and anthropogenic (local and transit) components of the watercourse water quality were determined in the case of the Belaya River. The mass of pollutants entering the water body from Ufa City territory through sources of different categories, including point and non-point, was estimated. It was established that the ratio of pollutant masses from point and non-point sources varies in different phases of water regime, depending on the pollutant type. In the study, it is shown that the system of river water quality monitoring should be improved taking into account the features of its formation within urban territory. 相似文献
