This article deals with assessment of changes in ice cover duration and maximum ice cover thickness for the last three decades compared with the previous period by the example of observation data for 28 hydrometric stations on rivers and 10 hydrological stations on lakes. Estimations of homogeneity and trends of long term serious of above mentioned...
A method for calculating the mean monthly sum of evaporation from the water surface using data from the continental GGI-3000 evaporation pan is proposed. It is based on zonal characteristic features of evaporation. A latitude was used as a zonality indicator. This method allows for calculating evaporation from the water surface for the months of Ju...
Department of hydrology, St. Petersburg State University, is the ancestor of higher hydrological education in the Russian Federation. The article presents the history of the hydrology department from its foundation to the present day, the role of outstanding scientists in the development of the department and the training of highly qualified specia...

At each of five fixed locations along the ground tracks of JASON-1 and ENVISAT, a repeat-track analysis of 1-Hz sea surface height (SSH) data has been conducted to assess the performance of wavefoim retrackers over Lake Baikal in Siberia, Russia. This simple analysis of time series at each point location is needed to minimize the effect of the rang...
Freshwater ice dominates the Arctic terrestrial environment and significantly impacts bio-physical and socio-economic systems.
Unlike other major cryospheric components that either blanket large expanses (e.g., snow, permafrost, sea ice) or are concentrated
in specific locations, lake and river ice are interwoven into the terrestrial landscape thro...
Climatic changes to freshwater ice in the Arctic are projected to produce a variety of effects on hydrologic, ecological,
and socio-economic systems. Key hydrologic impacts include changes to low flows, lake evaporation regimes and water levels,
and river-ice break-up severity and timing. The latter are of particular concern because of their effect...
Paleolimnological evidence from some Arctic lakes suggests that longer ice-free seasons have been experienced since the beginning
of the nineteenth century. It has been inferred from some additional records that many Arctic lakes may have crossed an important
ecological threshold as a result of recent warming. In the instrumental record, long-term...
The southern mountainous taiga of eastern Siberia has a sparse larch canopy and an understory dominated by a thick moss layer. The physiology of moss is very different from that of other plants, as mosses lack roots and vascular systems and take up water directly. During May 2002, we conducted hydrological and meteorological measurements in the tai...
More than 60% of river runoff from the Lena River basin originates in the southern mountainous region of eastern Siberia within the permafrost zone. We studied the transport of dissolved organic carbon (DOC) and particulate organic carbon (POC) within the Mogot Experimental Watershed, which is close to the drainage divide between the Lena and Amur...
The southern mountainous taiga region of eastern Siberia is the runoff source area of the basins of the rivers Lena and Amur, where snowmelt discharge is an important hydrological process. To evaluate the effect of the sparse larch forest canopy on snow ablation and energy balance in the snow-pack, meteorological conditions and snow ablation were o...
We attempted to clarify the runoff characteristics of a permafrost watershed in the southern mountainous region of eastern Siberia using hydrological and meteorological data obtained by the State Hydrological Institute in Russia from 1976 to 1985. We analysed seasonal changes in the direct runoff ratio and recession gradient during the permafrost t...
Snowmelt runoff is one of the most important discharge events in the southern mountainous taiga of eastern Siberia. The present study was conducted in order to understand the interannual variations in snowmelt infiltration into the frozen ground and in snowmelt runoff generation during the snowmelt period in the southern mountainous taiga in easter...
Snowmelt runoff is one of the most important discharge events in the southern mountainous taiga of eastern Siberia. The present study was conducted in order to understand the interannual variations in snowmelt infiltration into the frozen ground and in snowmelt runoff generation during the snowmelt period in the southern mountainous taiga in easter...
The freshwater discharge from the Arctic river basin to the Arctic Ocean is important for two connected reasons: (i) the extension of sea ice will occur in proportion to the amount of freshwater discharged, and (ii) climate change will occur due to variations in albedo effect as the amount of sea ice varies. Snowmelt runoff is the one of the most i...
The state-of-the-art of the hydrological network for the study of river-ice regimes in the Russian Arctic is reviewed as well as the regularly published documents that characterize specific features of ice events. The dates of the beginning of different ice events (e.g. ice drift, ice-cover formation, frazil ice drift, etc.) are analysed as well as...
On the basis of the hydrological observation data from the ROSHYDROMET network, a specialised database of ice events and ice thickness for the largest freshwater lakes and reservoirs of Russia has been established at the State Hydrological Institute. Observation periods vary between 116–118 years (for Lakes Onega and Ladoga, respectively) to 20 yea...
Freeze and breakup dates of ice on lakes and rivers provide consistent evidence of later freezing and earlier breakup around
the Northern Hemisphere from 1846 to 1995. Over these 150 years, changes in freeze dates averaged 5.8 days per 100 years later,
and changes in breakup dates averaged 6.5 days per 100 years earlier; these translate to increasi...
Though the history of reservoir construction is long enough, the effect of reservoirs on the environment has been studied quite insufficiently. This is evident from the errors made during reservoir design and construction that result in adverse ecological effects in the adjacent terrain. As far as the appearance of reservoirs on a historical scale...
A higher accuracy for a computation of individual balance components is attained by using up-to-date methodologies based, in particular, on the use multi-dimensional analysis methods. The report shows the results of applying a method of hydrometeorological fields separation into natural orthogonal components to compute precipitation onto the lake s...
Construction of large reservoirs on rivers causes major hydro- logical changes. Three typical zones are distinguished: the zone of filling, the shore zone with shallow water table around the reservoir, and the zone adjacent to the river channel downstream of the power plant, including the delta area of the river. In the first zone, runoff losses ar...
These changes are subdivided into temporary (observed during the period of reservoir filling and during the first years of its operation) and permanent (observed during the whole period of reservoir operation). The main types of temporary water resouces changes are runoff losses for filling the permanent pool and for groundwater recharge in bottom...
The results from electric analogue modelling the hydrodynamic conditions for formation of seepage loss from reservoirs are presented. A scheme of formation of the zone of seepage water accumulation in reservoir shores and a method quantitatively estimating the seepage loss are considered. Comparison is made between data on the saturation loss in th...
This section describes long-term observed climatic changes in atmospheric parameters. The focus is on surface climate conditions,
but changes in atmospheric circulation are discussed as they often are behind climatic variability seen on regional and local
scales. For a summary introduction on mean atmospheric states and conditions in the Baltic Sea...
The southern mountain taiga region is the water source of the Lena and Bikal basins. Ma et al. (2000) showed that most of the water in these rivers flows from south-eastern Siberia, which has heavy rain, especially in the summer. From August 2000 to May 2002, we made long-term observations of the water, energy, and carbon cycles on a catchment scal...
To understand water and energy cycle in Siberia, an intensive field campaign was carried out at a small watershed on the watershed-divide of the Lena and Amur rivers. The amounts of precipitation, discharge, evapotranspiration and interception loss, in the warm period from April 19 to October 13, 2001 (178 days) were 434.5mm, 204.7mm, 127.5mm, and...
The network for hydrological observations on small basins in the European Territory of Russia (ETR), described in this paper, is mainly intended to give information on the principal water cycle compo-nents for these basins. It will also allow the laws of interaction between water balance components to be established and will resolve some metho-dolo...
