    Simulating of multicomponent diffusion at industrial-waste migration in a heterogeneously layered medium (2015)
    Springer
    Details
    Publication Date: 2015-12-25
    Description: In most cases, the migration of groundwater from pollution sources takes place in heterogeneous media, the storage of which is mostly determined by nearly impermeable blocks of porous rocks, while the advection takes place through canals of small storage. The exchange between the blocks and the canals is commonly described by Fick’s law for each solution component separately. Nine-component solutions at waste disposal sites at Tomsk and Dimitrovgrad are used as examples to demonstrate the effects arising at such migration and making the results to differ (sometimes, considerably) from those derived from a model of independent diffusion.

    Groundwater resources in the Kolyma River valley and their changes caused by the operation of the Kolyma hydropower plant (2015)
    Springer
    Details
    Publication Date: 2015-12-25
    Description: The transformation of the formation conditions of natural freshwater resources caused by the construction of a water reservoir in the Kolyma River valley is considered. Water resources in the winter low-water season downstream the dam were found to increase many times, and a new groundwater recharge area appeared in the river valley between reservoir upper reaches and Ust’-Srednekan Settl. An increase in seepage loss from the reservoir cannot be ruled out, the more so after the construction of the Ust-Srednekansk Hydropower Plant.

    Active porosity and its effect on the physical mechanical properties of clay (2015)
    Springer
    Details
    Publication Date: 2015-12-25
    Description: The definition of active porosity given by B.N. Gumenskii is revised. The active porosity is taken to mean the bulk porosity less the pore space volume occupied by adsorbed water. The methods of calculating the active porosity discussed in the paper are based on finding the adsorbed-water volume at the maximal airdry moisture of soil and subtracting this value from the bulk porosity. The active porosity is shown to be important for assessing the reservoir and infiltration soil properties and a number of other characteristics used in soil mechanics.

    Assessing the dynamic parameters of exogenous geological processes based on one-time remote sensing data (2015)
    Springer
    Details
    Publication Date: 2015-12-25
    Description: A proof is given to a principal statement that even one remote sensing survey gives information on the quantitative dynamic parameters of exogenous geological processes. The models of mathematical morphology of landscape are shown to be a tool for obtaining such parameters. Methods for evaluating the dynamic parameters in the form of a series of special quantitative characteristics are identified; expressions for the dynamic parameters were obtained for lake–thermokarst, thermokarst–erosion, and alluvial plains.

    Principles of GIS support of geoenvironmental mapping at a regional level (2015)
    Springer
    Details
    Publication Date: 2015-12-25
    Description: The basic principles of the geoenvironmental mapping of a region are discussed. These include: (i) the informational software must comply with the intended purpose of geoenvironmental maps for territory-management and planning organizations; (ii) the mapping represents a sequential process—the result of each previous step is the input for the next step, and the result of the work is a set of maps. The database structure is proposed for the input and output mapping and statistical data. The geoenvironmental mapping is based on GIS software packages, which are used for assessing geosystems conditions and regional environmental planning.

    Evaluating the runoff of global-fallout cesium-137 from landscapes of the Ob river basin (2015)
    Springer
    Details
    Publication Date: 2015-12-25
    Description: The activity of cesium-137 from global atmospheric fallouts was studied in the soils of three 1 st order catchment basins in the taiga, subtaiga, and forest-steppe zones in the Ob basin. Cesium-137 runoff from those catchment basins was evaluated to give 0.48–5.0 in the taiga, 14.9–15.3 in the subtaiga, and 14.1–15.7 mCi km –2 . in the forest-steppe zones. The published data on sediment delivery coefficients and the leveloped typification of river basins were used to extrapolate the obtained data on 137 Cs runoff to the area of developed semihumid and humid river basins under natural vegetation. The runoff of global-fallout 137 Cs from the Ob Basin never exceeds 4% of its total reserves.

    Hydrogeochemical features of water-rock interaction in Verkhnekamskiy Saliferous Basin (2015)
    Springer
    Details
    Publication Date: 2015-12-25
    Description: The hydrogeochemical features of water interaction with soluble minerals are considered in the case of salt strata in Solikamsk Depression in natural (the area of the anticipated Verchnekamskaya Hydropower Plant) and technogenically transformed (the area of Berezniki T.) environments. The preservation of rock and potash salt is shown to be possible only upon maintaining the hydrogeochemical groundwater regime that provides the stability of gypsum facially replaced by salt. The gypsum protects the latter from contact with highly aggressive groundwater and, thus, from intense dissolution.

    Hydrogeological prerequisites for industrial waste injection during the development of priority area of the Yurubcheno–Tokhomo field (2015)
    Springer
    Details
    Publication Date: 2015-12-25
    Description: Detailed analysis of the geological and hydrogeological conditions in the Yurubcheno–Tokhomo zone of oil and gas accumulations showed the osinskii horizon of the Lower Cambrian to be of greatest interest for the disposal of large volumes of bottom and effluent water. Numerical physicochemical simulation of hydrogeochemical processes using a 3D model of groundwater flow between the injection well and the reservoir gave an estimate of the effect of industrial waste injection. The resulting changes in the mineralogical composition of the reservoir rock and its porosity-permeability are shown to be most considerable in the case of disposal of treated effluent water. The zone of technogenic metasomatosis, developing in the reservoir bed under the effect of waste disposal, was found to reach 800–840 m by the end of the fifth year of disposal site operation.
