Diagnostic modelling of within-water processes in reservoirs

The objectives of diagnostic calculations using mathematical models of reservoirs are formulated. The structure of a box hydrological model GMV-MGU is described, and the results of calculation of daily water balance, internal heat exchange structure, and heat balance of individual areas in the Mozhaisk and Rybinsk reservoirs are given. First results of calculation of variations in mean daily phytoplankton biomass in the near-dam pool of a weakly eutrophic water body in period of spring (diatoms) and summer (blue-green) blooming are presented.     

On the evaluation of displacement and deformation in tidal waves according to digital records of STS-2 and KSESh-R seismometers

A procedure for eliciting displacements in tidal waves from seismograms of broadband velocimeters like STS-2 and KSESH-R and the evaluation conversion of these displacements into vertical or volumetric deformation is proposed.     

Heavy metal concentrations in water and bivalved mollusks in different channel reaches of the Southern Bug River

Variations in Cd, Cr, Cu, and Fe concentrations in water and the soft tissues of bivalved mollusks Anodonta anatina and Unio tumidus along the Southern Bug River channel are examined. Fe concentration was found to be somewhat higher than the MAC. Cd, Cr, and Cu concentrations in water met the drinking water standards. The comparison of individual reaches of the channel in terms of heavy metal concentrations in mollusks allowed polluted river reaches to be identified. The highest Fe concentrations in the soft tissues of mollusks were recorded near the river source. The mollusks in the middle and lower reaches of the Southern Bug featured high accumulation of Cd, Cr, and Cu.     

Bottom sediments of the oldest reservoir in Moscow region

The methodological features and results of two soil surveys of the Senezh Reservoir carried out in 1992 and 2006 as a part of multidisciplinary limnological studies of this large recreation water body with the aim to monitor its ecological state and prepare recommendations for water protection measures are analyzed     

Multifunctional broad-band seismic assemblage SEP-1

Results of research and development of three velocimeter components in the form of an assemblage of mechanical seismic detector and boards of electronics, realizing stabilization of inertial mass zero point and formation of amplitude-frequency characteristic, are presented. Original electromagnetic system of mass suspension for the vertical variant is applied in the seismic detector; it gives a possibility of mass reduction to the variant of horizontal seismic detector without change of the general design. The suspension system consists of two cylindrical magnets and a ferromagnetic shunt. On the basis of the developed seismic detectors, design of the multifunctional seismic assemblage SEP-1 is realized allowing its application for solution of a wide variety of seismologic problems at measurements both in base variant and in wellholes.
