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.

Abstract. Integrated river-basin management for the Volga river requires understanding and modelling of the flow process in its macro-scale tributary catchments. At the example of the Kostroma catchment (16 000 km2), a method combining existing hydrologic simulation tools was developed that allows operational modelling even when data are scarce. Emphasis was placed on simulation of three processes: snow cover development using a snow-compaction model, runoff generation using a conceptual approach with parameters for seasonal antecedent moisture conditions, and runoff concentration using a regionalised unit hydrograph approach. Based on this method, specific regional characteristics of the precipitation-runoff process were identified, in particular a distinct threshold behaviour of runoff generation in catchments with clay-rich soils. With a plausible overall parameterisation of involved tools, spring flood events could successfully be simulated. Present paper mainly focuses on the simulation of a 16-year sample of snowmelt events in a meso-scale catchment. An example of regionalised simulation in the scope of the modelling system "Flussgebietsmodell" shows the capabilities of developed method for application in macro-scale tributary catchments of the Upper Volga basin.

In the Middle Holocene, favorable living conditions were formed environmental on the territory of the modern Upper Volga River, which, after the retreat of the latest glacier, abounded with a branched system of feeders. They contributed to the economic stability driven by hunting for elk and beaver, waterfowl and marsh birds, as well as intensive fishing. In the recent decades, it was considered proven that ceramics were perceived by the native population, and the Early Neolithic, thus, was developed on a local basis. The new data accumulated in recent years makes it possible to bring up this topic again. Natural, economic and cultural changes during the period from the end of the 7th to the beginning of the 6th millennium cal BC are considered on the example of the well-known multi-layer wetland site Zamostje 2, with preserved wooden fishing structures and a large number of bone and antler artefacts. The period of sharp climatic changes, known as the 8200 Cold Event, synchronous with the upper Mesolithic layer, influenced the site landscape, but, as it seems, did not affect the lifestyle of the local population. The comparison between the two main archaeological layers of the lake settlement — the Late Mesolithic Upper layer (LM UL) and the Early Neolithic (EN), represented by the Upper Volga culture (UVc), shows both clear traces of continuity, primarily in the structure of the economy and production toolkits as well as new cultural influences reflected in the types of projectile hunting weapons and fishing gear. The function of the Early Neolithic pots, reconstructed on the basis of lipid analysis, also indicates the preservation of the comprehensive Mesolithic diet.

We have undertaken extensive programs of natural radiocarbon measurement to date the evidence for various events buried in peat bogs. Two case studies are described here: 1) the chronological reconstruction of South Kamchatka volcanic eruptions and, 2) investigation of multi-layered archeological sites in the Upper Volga River Basin. Studies of sample composition and peat taphonomy allowed us to determine the source of 14C age deviations and to reconstruct the environmental history of organic matter accumulation. Data sets, obtained from different types of peat bog and containing traces of these Holocene events, are discussed.

В статье рассматриваются вопросы накопления тяжелых металлов в донных отложениях реки Волги в пределах Тверской области. Анализируются основные источники загрязняющих веществ. Дается характеристика концентраций тяжелых металлов в воде и донных отложениях. Приводится эколого-геохимическая оценка состояния донных грунтов Верхней Волги и Иваньковского водохранилища. The article deals with the accumulation of heavy metals in the bottom sediments of the Volga River within the Tver region. The main sources of pollutants are analyzed. The characteristics of the concentrations of heavy metals in water and bottom sediments are given. An ecological and geochemical assessment of the state of bottom soils of the Upper Volga and Ivankovskoye reservoir is given.

Abstract After the construction of the Volga Hydroelectric Station and other dams, migration routes of the Caspian lamprey were obstructed. The ecological niches vacated by this species attracted another lamprey of the genus Lampetra to the Upper Volga, which probably came from the Baltic Sea via the system of shipways developed in the 18 th and 19 th centuries. Based on collected samples and observations from sites in the Upper Volga basin, we provide diagnostic characters of adults, and information on spawning behavior. Silver coloration of Lampetra fluviatilis was noted for the first time and a new size-related subsample of “large” specimens was delimited, in addition to the previously described “dwarf”, “small” and “common” adult resident sizes categories. The three water systems: the Vyshnii Volochek, the Tikhvin and the Mariinskaya, are possible invasion pathways, based on the migration capabilities of the lampreys. Dispersal and colonization of the Caspian basin was likely a combination of upstream and downstreams migrations. First, the lampreys migrated upstream along the rivers of the Baltic basin until they reached the water-parting line, followed by mostly downstream dispersal into rivers of the Caspian basin. Dispersal in the Volga River was similar, in accordance with the migration cycle of this opportunistic lamprey species.
