Abstract Topical issues of modern geoecology related to the study of pollution of sediments of water bodies with heavy metals are considered. The Volga River basin, within which the research was carried out, is a rather heterogeneous picture, both in geological, geomophological and hydrological terms, and in technogenic development and use. A four-level taxonomy is presented in the selection of sites for monitoring, based on a combination of natural-landscape-climatic and technogenic factors. The highest taxon (areas of category I) includes the basins of reservoirs with the adjacent slopes and the residential and industrial-agricultural structures located within them. Within these areas, smaller taxa are distinguished - areas of category II - industrial and urban areas. Areas of category III are the small rivers without significant pollution and areas of category IV are for special observations. The principles of sampling sediments, the placement of observation points and the frequency of these events in time are considered. Examples of special observations when studying the intra-annual migration of heavy metals in the system "sediments - water column" at the Ivankovo reservoir of the Upper Volga are highlighted. The studies were carried out under conditions of a standard flow rate for a given reservoir and under conditions of slow water exchange.

The problems of modern geological ecology associated with the study of pollution of sediments of water bodies by heavy metals are considered. The Volga River basin is quite heterogeneous, both in geomorphological and hydrological terms, and in thechnogenical development and usage. A fourrank taxonomy is presented for the selection of sites for monitoring, based on a combination of natural, landscape, climatic and thechnogenical factors. To the largest – the highest taxon – sites of the Ist category – bowls of reservoirs with the slopes and the urban zones, industrial and agricultural structures located within them are carried. Within these areas are allocated to smaller taxa, areas category IInd are the industrial and urban zones, areas category IIIrd are the small rivers without significant contamination and areas category IVth to conduct special observations. The examples of special observations in the study of the annual migration of heavy metals in the system «bottom sediments – water column» on the Ivankovo reservoir are highlighted. The investigations were carried out under the conditions of the standard flow rate for this reservoir and in the conditions of slow water exchange.

The City

The latest special studies of the genus Synura in Russia were conducted in the 1970s. In the last decade, 14 new species of the genus were described based on molecular and morphological data. The total number of valid taxa of the genus has increased to 49. Only 18 taxa of Synura are known in Russia up to date, and the diver sity of the genus on this huge territory is strongly underestimated. Previous studies of the genus were focused mainly on large lakes or reservoirs. To reveal a more complete flora, it is necessary to include other habitats into account. Small urban rivers can be prospective habitats for interesting taxa including synuralean algae. Our study focuses on the taxonomic composition of the genus Synura in four small rivers in Nizhniy Novgorod (European Russia): Chyornaya, Levinka, Borzovka and Rzhavka. All the rivers flow in the city and fall under strong anthropogenic impact. The genus Synura was studied by means of transmission and scanning electron microscopy during 2011, 2012, 2014, 2015. In total, eight species and one form of Synura have been found: S. conopea, S. curtispina, S. echinulata, S. glabra, S. macropora, S. petersenii, S. spinosa f. spinosa, S. spinosa f. longispina, S. uvella. All nine taxa were observed in the river Chyornaya. Five taxa were found in the rivers Levinka, Borzovka and Rzhavka. One species (Synura conopea) is a new record to the flora of Russia. It was found in all studied rivers. Four taxa (S. conopea, S. glabra, S. macropora, S. spinosa f. longispina) are new records to the Middle Volga river basin.

Resource Data

The Water Problem Institute of the Russian Academy of Science and the Tennessee Valley Authority are participating in a joint project to demonstrate the use of geographic information systems (GIS) in managing water resources under the changing economic system in Russia. The purpose is to improve decisions by better organizing, analyzing, and presenting water resource data and management options. Results to date include development of a conceptual approach and review of existing data. The project area includes the Upper Volga River Basin which encompasses the Moscow metropolitan area. Data are being managed at three levels depending on the scale and detail (i.e., regional, watershed, and local). Initial conclusions indicate a great potential for this technology, but many obstacles due to the current economic situation.
