SUMMARYSixteen strains of leptospires were isolated from surface water (14 in England and 2 in Italy) and were classified. They were all saprophytic, and nine of them belonged to known serovars: the others were found to represent new serovars within already known serogroups.

Key Terms

The author reveals key terms of water law — water fund and water objects in c ontext of various relationships. The author discloses correlation of these terms with the concepts of real estate, watersectoral complex; understands said terms through the prism of state surveillance, account and zoning of water fund. Water objects of common usage are also inspected by the author. The following methods of scientific research are used: historic retrospective, comparative analyze and extrapolation. Experience of EU, CIS and other countries is taken into account. The article exposes the views and breakthrough ideas of leading scientists of modern jurisprudence (T. Y. Khabrieva, Yu. A. Tikhomirov, M. M. Brinchuk, S. A. Bogolyubov, O. S. Kolbasov, O. I. Krassov), some representatives of the natural sciences and mass media. Russian water fund is not only a basis of water sector, but also is a permanent basis of all economy. Degradation of quality and reduction of quantity of water resources inevitably would harm the wellbeing of the Russian society. Norms of Soviet and Russian legislation are presented by the author in a critical manner. The author inspects the classification of water objects, which is important for the state water fund. As it is stated in article 5 of Russian Water Code, depending on the features of the regime, geographical, morphometric and other features, water objects have complicated gradation. For the purposes of this article, first of all it is important to divide the surface and underground water objects. According to the article 5 of Russian Water Code, the term “surface water object” includes not only water masses, but also covered land within the coastline. These are the necessary features of surface water objects — connection of land and water. In this regard, a difficult question is attended to as of whether the surface water objects have in their structure real estate.

Management Plans

Abstract Water management plans require comprehensive knowledge of physical processes and principles controlling water resources. These mechanisms, subject to limitations, can interact in complex ways, which makes it challenging to design guidelines to achieve optimum water resources use, taking into account economic, social and environmental factors. The relationship between rivers and aquifers defines different forms of interaction between superficial water and groundwater. These processes have great relevance in inland water management and protection against pollution, as well as dependent ecosystems. Under the current legislative framework in Europe, i.e., the Water Framework Directive 2000/60/EC (WFD) and the Groundwater Directive 2006/118/EC, calculation of flow direction and exchange rates between groundwater bodies and associated surface systems are key aspects of river basin management plans. This paper examines conditioning factors of exchange processes, related basic physical principles, and criteria for establishing different conceptual models, providing a typology for systematic classification of groundwater–surface water interactions.

Abstract. Surface water concentrations of CO2, CH4, and N2O have rarely been measured simultaneously in river systems modified by human activities, contributing to large uncertainties in estimating global riverine emissions of greenhouse gases (GHGs). Basin-wide surveys of the three GHGs were combined with a small number of measurements of C isotope ratios in dissolved organic matter (DOM), CO2, and CH4 in the Han River basin, South Korea, to examine how longitudinal patterns of the three gases and DOM are affected by four cascade dams along a middle section of the North Han River (hereafter termed “middle reach”) and treated wastewater discharged to the lower Han River (“lower reach”) traversing the Seoul metropolitan area. Monthly monitoring and two-season comparison were conducted at 6 and 15 sites, respectively, to measure surface water gas concentrations and ancillary water quality parameters including concentrations of dissolved organic carbon (DOC) and optical properties of DOM. The basin-wide surveys were complemented with a sampling cruise along the lower reach and synoptic samplings along an urban tributary delivering effluents from a large wastewater treatment plant (WWTP) to the lower reach. The levels of pCO2 were relatively low in the middle reach (51–2465 µatm), particularly at the four dam sites (51–761 µatm), compared with those found in the largely forested upper basin with scattered patches of croplands (163–2539 µatm), the lower reach (78–11298 µatm), and three urban tributaries (2120–11970 µatm). The upper and middle reaches displayed generally low concentration ranges of CH4 and N2O, with some local peaks influenced by agricultural runoff and impoundments. By comparison, the lower reach exhibited exceptionally high concentrations of CH4 (1.2–15766 nmol L−1) and N2O (7.5–1396 nmol L−1), which were significantly correlated with different sets of variables such as DO and PO43- for CH4 and NH4+ and NO3- for N2O. Downriver increases in the levels of DOC and optical properties such as fluorescence index (FI) and protein-like fluorescence indicated an increasing DOM fraction of anthropogenic and microbial origin. The concentrations of the three GHGs and DOC were similar in magnitude and temporal variation at a WWTP discharge and the receiving tributary, indicating a disproportionate contribution of the WWTP effluents to the tributary gas and DOC exports to the lower reach. The values of δ13C in surface water CO2 and CH4 measured during the sampling cruise along the lower reach, combined with δ13C and Δ14C in DOM sampled across the basin, implied a strong influence of the wastewater-derived gases and aged DOM delivered by the urban tributaries. The downstream enrichment of 13C in CO2 and CH4 suggested that the spatial distribution of these gases across the eutrophic lower reach may also be constrained by multiple concomitant processes including outgassing, photosynthesis, and CH4 oxidation. The overall results suggest that dams and urban wastewater may create longitudinal discontinuities in riverine metabolic processes leading to large spatial variations in the three GHGs correlating with different combinations of DOM properties and nutrients. Further research is required to evaluate the relative contributions of anthropogenic and in-stream sources of the three gases and DOM in eutrophic urbanized river systems and constrain key factors for the contrasting impoundment effects such as autotrophy-driven decreases in pCO2 and in-lake production of CH4 and N2O.
